tuberculosis
an infectious disease caused by mycobacterium tuberculosis that usually attacks the lungs; also known as TB, it can also affect other parts of the body
80
Respiratory System
supplies the blood with oxygen for transportation to the cells in all parts of the body. Oxygen is vital to the survival and function of these cells. The respiratory system also removed carbon dioxide and some water waste from the body.
81
upper respiratory tract
consists of the nose (nostrils), mouth, pharynx, epiglottis, larynx and trachea
82
lower respiratory tract
consists of the bronchial tree and lungs. These structures are located within and protected by the thoracic cavity, or thorax, also known as the rib cage
83
the upper respiratory tract and the bronchial tree of the lower respiratory tract are sometimes referred to as the airway
84
nose
air enters the body through the nose and passes through the nasal cavity
85
nostrils
external openings of the nose
86
nasal septum
is a wall of cartilage that divides the nose into two equal sections.
87
septum
is a wall that separates two chambers
88
cilia
thin hairs located just inside the nostrils, filter incoming air to removing debris
89
mucous membranes
line the nose. These specialized tissues also line the digestive, reproductive, and urinary systems as well as other parts of the respiratory system
90
mucus
a slippery secretion produced by the mucous membranes that protect and lubricates these tissues. In the nose, the mucus helps moisten, warm, and filter the air as it enters.
91
mucous
name of the tissue
92
mucus
the secretion that flows from the tissue
93
olfactory receptors
are nerve endings that act as the receptors for the sense of smell. They are also important to the sense of taste. These receptors are located in the mucous membrane in the upper part of the nasal cavity - humans have 12 million receptor cells for smell in the upper extreme upper region of the nasal cavity (olfactory region)
94
tonsils and adenoids
help protect the body from infection coming through the nose or the mouth.
95
palatine tonsils
also known as the tonsils, are located at the back of the mouth
96
nasopharyngeal tonsils
also known as the adenoids, are higher up, behind the nose and the roof of the mouth
97
paranasal sinuses
air-filled cavities lined with mucous membrane, are located in the bones of the skull
98
sinus
can be a sac or cavity in any organ or tissue, however the term sinus more commonly refers to the paranasal sinusesf
99
functions of the sinuses are:
1. to make the bones of the skull lighter
2. to help produce sound by giving resonance to the voice
3. to produce mucus to provide lubrication for the tissues of the nasal cavity.
The sinuses are connected to the nasal cavity via short ducts. The four pairs of paranasal sinuses are located on either side of the nose and are named for the bones in which they are located
100
frontal sinuses
are located in the frontal bone just above the eyebrows. An infection here can cause severe pain in this area
101
sphenoid sinuses
are located in the sphenoid bone behind the eye and under the pituitary gland, are close to the optic nerves, and an infection here can damage vision
102
maxillary sinuses
are the largest of the paranasal sinuses, are located in the maxillary bones under the eyes. An infection in these sinuses can cause pain in the posterior maxillary teeth
103
ethmoid sinuses
are located in the ethmoid bones between the nose and the eyes, are irregularly shaped air cells that are separated from the orbital (eye) cavity by only a thin layer of bone
104
pharnyx
commonly known as the throat, receives the air after it passes through the nose or mouth, as well as food.
105
pharynx is made up of three division
nasopharynx
oropharynx
laryngopharynx
106
Nasopharynx
the first division, is posterior to the nasal cavity and continues downward to behind the mouth. This portion of the pharynx is used only by the respiratory system for the transport of air and opens into the oropharynx
107
oropharynx
which is the second division, is the portion that is visible when looking into the mouth. The oropharynx is shared by the respiratory and digestive systems and transports air, food, and fluids downward to the laryngopharynx
108
laryngopharynx
which is the third division, is also shared by both the respiratory and digestive systems. Air, food, and fluids continue downward to the openings of the esophagus and trachea where air enters the trachea and food and fluids flow into the esophagus.
109
larynx
also known as the voice box, is a triangular chamber located between the pharynx and the trachae
110
Thyroid cartilage
the largest in supporting the larynx, which is supported by a series of nine separate cartilages. The thyroid cartilage is also known as the Adam's apple
111
Larynx contains
the vocal cords. During breathing, the cords are separated to let air pass. During speech, they close together, and sound is produced as air is expelled from the lungs, causing the cords to vibrate against each other
112
Protective Swallowing Mechanisms
respiratory and digestive system share part of the pharynx. During swallowing, there is a risk of a blocked airway or aspiration pneumonia caused by food or water going into the trachea and entering the lungs instead of going into the esophagus. Two protective mechanisms act automatically during swallowing to ensure that only air goes into the lungs:
The soft plate, which is the muscular posterior portion of the roof of the mouth, moves up and backward during swallowing to close off the nasopharynx. This prevents food or liquid from going up the nose.
At the same time the epiglottis, which is a lid-like structure located at the base of the tongue, swings downward and closes off the laryngopharynx so that food does not enter the trachea and lungs
113
epiglottis
a lid-like structure located at the base of the tongue, swings downward and closes off the laryngopharynx so that food does not enter the trachea and lungs
114
trachea
is to transport air to and from the lungs. This tube, which is commonly known as the windpipe, is located directly in front of the esophagus
115
Trachea is held open
by a series of flexible C-shaped cartilage rings that make it possible for the trachea to compress so that food can pass down the esophagus
116
bronchi
are two large tubes, also known as primary bronchi, which branch out from the trachea and convey air into the two lungs (singular, bronchus). Because of the similarity of these structures to an inverted tree, this is referred to as the bronchial tree
Within the lung, each primary bronchus divides and subdivides into increasingly smaller bronchioles, which are the smallest branches of the bronchi
117
Alveoli
also known as air sacs, are the very small, grapelike clusters found at the end of each bronchiole (singular, alveolus). The alveoli are where the exchange of oxygen and carbon dioxide takes place. Each lung contains millions of alveoli.
During respiration, the alveoli are filled with air from the bronchioles.
A network of microscopic pulmonary capillaries surrounds the alveoli. Pulmonary means relating to or affecting the lungs.
The exchange of oxygen and carbon dioxide between the air inside the alveoli and the blood in the pulmonary capillaries occurs through the thing, elastic walls of the alveoli
The alveoli produce a detergent-like substance, known as surfactant, which reduces the surface tension of the fluid in the lungs. This makes the alveoli more stable so they do not collapse when an individual exhales. Premature babies often lack adequate surfactant
118
lungs
which are the essential organs of respiration, are divides into lobes.
The right lung is larger and has three lobes: the upper, middle, and lower (or superior, middle, and inferior)
The left lung has only two lobes, the upper and lower, due to space restrictions because the heart is located on that side of the body
119
mediastinum
is the middle section of the chest cavity and is located between the lungs. The cavity contains connective tissue and organs, including the heart and its veins and arteries, the esophagus, trachea, bronchi, the thymus gland, and lymph nodes
120
Pleura
allows the lungs to move smoothly within the chest
121
parietal pleura
is the outer layer of the pleura. It lines the walls of the thoracic cavity, covers the diaphragm, and forms the sac containing each lung. the parietal pleura is attached to the chest wall. Parietal means relating of the walls of a cavity.
122
visceral pleura
which is the inner layer of pleura that covers each lung, is attached directly to the lungs. Visceral means relating to the internal organs
123
pleural cavity
also known as the pleural space, is the thing, fluid-filled space between the parietal and visceral pleural membranes. The fluid acts as lubricant, allowing the membranes to slide easily over each other during respiration
124
diaphragm
also known as the thoracic diaphragm, is a dome-shaped sheet of muscle that separates the thoracic cavity from the abdomen. It is the contraction and relaxation of this muscle that makes breathing possible
125
phrenic nerves
stimulate the diaphragm and cause it to contract
126
diaphragm
refers to a dividing structure, so the term is also used to describe a contraceptive device that separates the vagina from the cervix
127
respiration
or breathing is the exchange of oxygen for carbon dioxide that is essential to life. A single respiration, or breath, consists of one inhalation and one exhalation. Ventilation is another word for moving air in and out of the lungs.
128
inhalation
is the act of taking in air as the diaphragm contracts and pulls downward. this action causes the thoracic cavity to expand. This produces a vacuum within the thoracic cavity that draws air into the lungs
129
exhalation
is the act of breathing out. As the diaphragm relaxes, it moves upward, causing the thoracic cavity to become narrower. This action forces air out of the lungs
130
external respiration
is the act of bringing air in and out of the lungs from the outside environment and, in the process, exchanging oxygen for carbon dioxide
-As air is inhaled into the alveoli, oxygen immediately passes into the surrounding capillaries and is carried by the erythrocytes (red blood cells) to all body cells.
-At the same time, the waste product carbon dioxide that has passed into the bloodstream is transported into the air spaces of the lungs to be exhaled
131
Internal respiration
also known as cellular respiration, is the exchange of gases within the cells of the blood and tissues
-In this process, oxygen passes from the bloodstream into the cells
-The cells give off the waste product carbon dioxide, which passes into the bloodstream
-The bloodstream transports the carbon dioxide to the lungs, where it is expelled during exhalation
132
otolaryngologist
also known as an ENT, is a physician with specialized training in the diagnosis and treatment of diseases and disorders of the head and neck
133
pulmonologist
is a physician who specializes in diagnosing and treating diseases and disorders of the respiratory system
134
thoracic surgeon
performs operations on the organs inside the thorax, or chest, including the heart, lungs, and esophagus
135
Chronic obstructive pulmonary disease (COPD)
is a group of lung diseases in which the bronchial airflow is obstructed, making it difficult to breathe out. COPD, which is most often caused by long-term smoking, is generally permanent and progressive. Most people with COPD suffer from two related conditions: chronic bronchitis and emphysema
136
Chronic bronchitis
is a disease in which the airways have become inflamed due to recurrent exposure to an inhaled irritant, usually cigarette smoke. An increase in the number and size of mucus-producing cells results in excessive mucus production and thickening of the walls of the air passages. This causes chronic coughing, difficulty getting air in and out of the lungs, and increased risk of bacterial lung infections
137
emphysema
is the progressive, long- term loss of lung function, usually due to smoking. Emphysema is characterized by a decrease in the total number of alveoli, enlargement of the remaining alveoli, and the progressive destruction of the walls of the remaining alveoli.
As the alveoli are destroyed, breathing becomes increasingly rapid, shallow, and difficult. In an effort to compensate for the loss of capacity, the lungs chronically over inflate, and the rib cage stays partially expanded all the time, resulting in a slightly rounded shape called a barrel chest.
138
Asthma
is a chronic inflammatory disease of the bronchial tubes, often triggered by an allergic reaction
139
Asthma attack
is characterized by episodes of severe breathing difficulty, coughing, and wheezing
140
Wheezing
is a breathing sound caused by a partially obstructed airway. The frequency and severity of asthma attacks are influenced by a variety of factors, including allergens, environmental agents, exercise, and infection

172
pneumothorax
is the accumulation of air in the pleural space resulting in a pressure imbalance that causes the lung to fully or partially collapse. This can have an external cause, such as a stab wound through the chest wall, or it can occur when there is a lung-disease-related rupture in the pleura that allows air to leak into the pleural space
173
acute respiratory distress syndrome (ARDS)
is a lung condition usually caused by trauma, pneumonia, smoke or fumes, inhaled vomit, or sepsis.
174

-TB occurs most commonly in individuals whose immune systems are weakened by another condition such as AIDS. A healthy individual can carry latent TB without showing symptoms of the disease. Latent means present but not active
181
Multidrug-resistant tuberculosis
is a dangerous form of the disease that can occur when the prescribed drug regimen is not strictly followed, rendering the treatment insufficient to destroy all the bacteria
182
pneumonia
is a serious inflammation of the lungs in which the alveoli and air passages fill with pus and other fluids
-Pneumonia is most commonly caused by an infection and often follows a cold, flu, chronic illness, or other condition, especially in the elderly, that weakens the immune system and its ability to stave off infection.
183
pneumon
means lung
184
There are two types of bacterial pneumonia named for the parts of the lungs affected, these are:
Bronchopneumonia and lobar pneumonia
185
bronchopneumonia
is a localized form of pneumonia that often affects the bronchioles. Bronchopneumonia often leads to lobar pneumonia
186
lobar pneumonia
affects larger areas of the lungs, often including one or more sections, or lobes, of a lung.
187
Double pneumonia
is lobar pneumonia involving both lungs and is usually a form of bacterial pneumonia
188
pneumonia named for the causative agent
as many as 30 causes of pneumonia have been identified; however, the most common causative agents are air pollution, bacteria, fungi, viruses, and inhaled liquid or chemicals
189
aspiration pneumonia
can occur when a foreign substance, such as vomit, is inhaled into the lungs. As used here, aspiration means inhaling or drawing a foreign substance into the upper respiratory tract
190
bacterial pneumonia
is almost commonly caused by streptococcus pneumonia.
191
pneumococcal pneumonia
is the only form of pneumonia that can be prevented through vaccination
192
community-acquired pneumonia (CAP)
is any pneumonia that results from contagious infection outside of a hospital or clinic. CAP may be bacterial pneumonia or be caused by a virus or fungi. This is the most common form of pneumonia, and it affect people of all ages
193
Hospital-acquired pneumonia
or nosocomial pneumonia, is a type of pneumonia contracted during a stay in the hospital when a patient's defenses are impaired. Patients on a ventilator are particularly at risk.
194
Nosocomial
means hospital-acquired
195
walking pneumonia
also known as mycoplasma pneumonia, is a milder but longer-lasting form of the disease caused by the bacteria Mycoplasma pneumoniae. It get its name from the fact that the patient is often not bedridden
196
pneumocystis pneumonia
is an opportunistic infection caused by the yeast-like fungus pneumocystis carinii.
197
Viral pneumonia
which can be caused by several different types of viruses, accounts from approximately a third of all pneumonias
198
interstitial lung disease
refers to a group of almost 200 disorders that cause inflammation and scarring of the alveoli and their supporting structures.
199
interstitial
means relating to spaces within or around a tissue or an organ. In these lung conditions the tissue around the alveoli becomes scarred or stiff, leading to a reduction of oxygen being transferred to the blood
200
pulmonary fibrosis
or interstitial fibrosis, is the progressive formation of scar tissue in the lung, resulting in decreased lung capacity and increased difficulty in breathing.
201
Fibrosis
is a condition in which normal tissue is replaced by fibrotic (hardened) tissue
-Many connective tissue diseases such as rheumatoid arthritis, scleroderma, and lupus can cause pulmonary fibrosis, as can environmental toxins such as asbestos and silica. Pulmonary fibrosis can also occur without a known cause

208
lung cancer
which is the leading cause of cancer death in the United States, is a condition in which cancer cells form in the tissues of the lung. Important risk factors for lung cancer are smoking and inhaling secondhand smoke
209
breathing disorders
describes abnormal changes in the rate or depth of breathing. Specific terms describe in greater detail the changes that are occuring.
210
Eupnea
is easy or normal breathing. This is the baseline for judging some breathing disorders. Eupnea is the opposite of apnea
211
apnea
is the temporary absence of spontaneous respiration. It is a common respiratory problem in premature infants. Apnea is the opposite of eupnea
212
bradypnea
is an abnormally slow rate of respiration, usually of less than 10 breaths per minute. Bradypnea is the opposite of tachypnea
213
Cheyne-Stokes respiration
is an irregular pattern of breathing characterized by alternating rapid or shallow respiration followed by slower respiration or apnea. This pattern sometimes occurs in comatose patients or those nearing death
214
tachypnea
is an abnormal rapid rate of respiration, usually of more than 20 breaths per minute. Tachypnea is the opposite of bradypnea
215
dyspnea
is also known as shortness of breath (SOB), is difficult or labored breathing. Shortness of breath is frequently one of the first symptoms of heart failure. It can also be caused by strenuous physical exertion or can be due to lung damage that produces dyspnea even at rest
216
hyperpnea
which is commonly associated with exertion, is breathing that is deeper and more rapid than is normal at rest. Hyperpnea may also occur at high altitude or be caused by anemia or sepsis. Hyperpnea is the opposite of hypopnea
217
hypopnea
is shallow or slow respiration. Opposite of nyperpnea
218
Hyperventilation
is an abnormally rapid rate of deep respiration that is usually associated with anxiety. This decreases the level of carbon dioxide in the blood, causing dizziness and tingling in the fingers and toes
219
sleep apnea
is a potentially serious disorder in which breathing repeatedly stops and starts during sleep for periods long enough to cause a measurable decrease in blood oxygen levels.
220
Obstructive sleep apnea (OSA)
is caused by the muscles at the back of the throat relaxing and narrowing the airways
221
snoring
which can be a symptom of sleep apnea, is noisy breathing caused by virbration of the soft palate
222
expectoration
is the act of coughing up and spitting out saliva, mucus, or other body fluid

224
airway obstruction
commonly known as choking, occurs when food or a foreign object partially or completely blocks the airway and prevents air from entering or leaving the lungs. This can be a life-threatening emergency requirement immediate action through the performance of abdominal thrusts. This is also known as the heimlich maneuver
225
anoxia
is the absence of oxygen from the body's tissues and organs even though there is an adequate flow of blood. If anoxia continues for more than 4 to 6 minutes, irreversible brain damage can occur
226
hypoxia
is the condition of having deficient oxygen levels in the body's tissues and organs; however, it is less severe than anoxia. This condition can be caused by a variety of factors, including head trauma, carbon monoxide poisoning, suffocation, and high altitudes. Compare with hypoxemia
227
Altitude hypoxia
also known as altitude sickness, is a condition that can be brought on by the decreased oxygen in the air at higher altitudes, usually above 8,000 feet
228
asphyxia
is the loss of consciousness that occurs when the body cannot get the oxygen it needs to functions. Asphyxia can be caused by chocking, suffocation, drowning, or inhaling gases such as carbon monoxide
229
asphyxiation
is a state of asphyxia or suffocation. in this life-threatening condition, oxygen levels in the blood drop quickly, carbon dioxide levels rise, and unless the patient's breathing is restored within a few minutes, death or serious brain damage follows
230
cyanosis
is a bluish discoloration of the skin and mucous membranes caused by a lack of adequate oxygen in the blood
231
hypercapnia
is the abnormal buildup of carbon dioxide in the blood
232
hypoxemia
is the condition of having low oxygen levels in the blood, usually due to respiratory disorders or heart conditions. compare with hypoxia
233
Respiratory failure (RF)
also known as respiratory acidosis, is a condition in which the level of oxygen in the blood becomes dangerously low (hypoxemia) or the level of carbon dioxide becomes dangerously high (hypercapnia). It is a medical emergency that can result from a chronic condition or develop suddenly
234
smoke inhalation
is damage to the lungs in which particles from a fire coat the alveoli and prevent the normal exchange of gases
235
Sudden infant death syndrome (SIDS)
is the sudden and unexplainable death of an apparently healthy sleeping infant between the ages of 2 and 6 months. Although the cause of SIDS is still unknown, the "Safe to Sleep" (formerly "Back to Sleep") campaign recommending that infants sleep on their back instead of facedown with no blankets, pillows, or toys in the crib has significantly reduced the incidence of SIDS
236
respiratory rate
which is an important vital sign, is a count of the number of breaths (one inhalation and one exhalation) per minute
237
Respiratory sounds
such as rales, rhonchi, and stridor provide information about the condition of the lungs and pleura.
238
bronchoscopy
is the visual examination of the bronchi using a bronchoscope.
239
A bronchoscope
is a flexible, fiberoptic device that is passed through the nose or mouth and down the airways. It can also be used for operative procedures, such as tissue repair or the removal of a foreign object
240
chest x-ray
also known as chest imaging, is a valuable tool for diagnosing pneumonia, lung cancer, pneumothorax, pleural effusion, tuberculosis, and emphysema
241
laryngoscopy
is the visual examination of the larynx and vocal cords using a flexible or rigid laryngoscope inserted through the mouth.

250
sputum
is phlegm ejected through the mouth that can be examined for diagnostic purposes
251
phlegm
is thick mucus secreted by the tissues lining the respiratory passages
252
The two kinds of tests to detect tuberculosis infection
tuberculin skin testing and blood tests
253
Tuberculin skin testing
also known as Mantoux PPD Skin test, is screening test for tuberculosis in which a very small amount of PPD tuberculin (a purified protein derivative) is injected just under the top layer of the skin on the forearm. The site is checked for a reaction 48-72 hours later.
-A positive result from either a skin or blood test indicates the possibility of exposure to the disease, and this response warrants further testing such as a chest x-ray and sputum cytology
254
antitussive

255
tuss
cough
256

257
bronchodilator
is an inhaled medication that relaxes and expands the bronchial passages into the lungs. Patients with asthma use short-acting bronchodilators as needed as rescue medications, while long-acting bronchodilators are used every day to control the condition
258
metered-dose inhaler (MDI)
administers a specific amount of a medication such as bronchodilator in aerosol form. A gas propellant mixes with the medicine to push it into the lungs
259
nebulizer
is an electronic device that pumps air or oxygen through a liquid medicine to turn it into a mist, which is then inhaled by the patient via a face mask or mouthpiece.
260
Most people with asthma take two kinds of medicine:
controller medicines
Quick-relief, or rescue medicines
261
controller medicines
such as inhaled corticosteroids, are long-acting medications taken daily to prevent attacks. These medications help control inflammation and stop the airways from reacting to the factors that trigger the asthma
262
quick-relief, or rescue medicines
are taken at the first sign of an attack to dilate the airways and make breathing easier. Corticosteroids may also be given intravenously during a severe attack
263
endotracheal intubation (ETT)
is the passage of a tube through the mouth into the trachea to establish or maintain an open airway, especially when a patient is on a ventilator.
264
Intubation
is the insertion of a tube, usually for the passage of air or fluids
265
Functional endoscopic sinus surgery (FESS)
is a procedure performed using an endoscope in which chronic sinusitis is treating by enlarging the opening between the nose and sinus
266
laryngectomy
is the surgical removal of the larynx
267
laryngotomy
is a surgical incision into the larynx, performed when the upper part of the airway is obstructed
268
Septoplasty
is the surgical repair or alteration of parts of the nasal septum
269
tracheostomy
is the surgical creation of a stoma into the trachea to insert a temporary or permanent tube to facilitate breathing. The term tracheostomy is used to refer to the surgical procedure and to the stoma itself.
270
stoma
means a surgically created opening on a body surface
271
tracheotomy
is a procedure in which an incision is made into the trachea to gain access to the airway below a blockage
272
pneumonectomy
is the surgical removal of all or part of a lung
273
lobectomy
is the surgical removal of a lobe of an organ, usually the lung, brain, or liver
274

is a surgery in which as small wedge-shaped piece of cancerous lung tissue is removed, along with a margin of healthy tissue around the cancer
275
thoracentesis
is the surgical puncture of the chest wall with a needle to obtain fluid from the pleural cavity. This procedure is performed to remove liquid (pleural effusion) or air (pneumothorax) from the pleural cavity
276
thoracotomy
is a surgical incision into the chest walls to open the pleural cavity for biopsy or treatment. A thoracotomy is used to gain access to the lungs, heart, esophagus, diaphragm, and other organs
277
video-assisted thoracic surgery (VATS)
is the use of a thoracoscope to view the inside of the pleural cavity through very small incisions.
278
thoracoscope
is a specialized endosscope used for treating the thorax. This procedure is used to remove small sections of cancerous tissue and to obtain biopsy specimens to diagnose certain types of pneumonia, infections, or tumors of the chest wall. It is also used to treat repeatedly collapsing lungs
279
Treatments for cystic fibrosis include:
pancreatic enzymes
chest percussion
280
pancreatic enzymes
to aid the digestive system as well as bronchodilators to keep airways open
281
chest percussion
which is a therapeutic technique to remove excess mucus from the lungs. This is often performed with the patient positioned at an angle to allow gravity to help drain the secretions
282
diaphragmatic breathing
also known as abdominal breathing, is a relaxation technique used to relieve anxiety
283
CPAP Machine
(continuous positive airway pressure) is a noninvasive ventilation device used in the treatment of sleep apnea. A face mask is connected to a pump that creates constant air pressure in the nasal passages, holding the airway open. Although this does not cure sleep apnea, it does reduce snoring and prevents dangerous apnea disturbances
284
BiPAP maachine
(bilevel positive airway pressure) is like a CPAP machine; however, it can be set at a higher pressure for inhaling and a lower pressure for exhaling. It is used for sleep apnea in patients with neuromuscular diseases or those who find the CPAP machine uncomfortable
285
Ambu bag or bag valve mask (BMV)
is an emergency resuscitator used to assist ventilation. A flexible air chamber is squeezed to force air through a face mask into the lungs of the patient, a process referred to as "bagging"
286
ventilator
is a mechanical device for artificial respiration that is used to replace or supplement the patient's natural breathing function. The ventilator forces air into the lungs; exhalation takes place passively as the lungs contract
287
supplemental oxygen
is administered when the patient is unable to maintain an adequate oxygen saturation level in the blood from breathing normal air. Oxygen is administered by using a compressor either flowing into a hood or tent or delivered directly to the patient using one of the following:
-Nasal cannula
-rebreather mask
-non-rebreather mask
288
nasal cannula
a small tube that divides into two nasal prongs
289
rebreather mask
allows the exhaled breath to be partially reused, delivering up to 60% oxygen
290
non-rebreather mask
allows higher levels of oxygen to be added to the air taken in by the patient
291
hyperbaric oxygen therapy
involves breathing pure oxygen in a special chamber that allows air pressure to be raised up to three times higher than normal. The lungs and the bloodstream are thus able to absorb more oxygen, which is delivered throughout the body to promote healing and fight infection

312
Common symptoms of lung cancer:
-cough
-wheezing
-SOB
-hempotysis (blood-tinged sputum)
-chest pain
-voice hoarseness
313
Two main categories of lung cancer
small cell lung cancer
non-small cell lung cancer
314
small cell lung cancer
is found in 10-15 percent of patients
315
non-small cell lung cancer
includes most other types of lung cancer and is found in the remaining 85-90 percent of patients. There are subcategories of non-small cell lung cancer, the most common of which are adenocarcinoma, squamous cell carcinoma, and large cell carcinoma
316
difference between small cell and non-small cell cancers
small cell cancers grow and metastasize differently. Small cell cancer tends to be more aggressive and can spread quickly. Small and non-small cancers have different treatment regimens for surgery, radiation and chemo
317
mesothelioma
is a tumor of the tissue that lines the pleura. It is a disease of people who worked at jobs where they inhaled asbestos particles. It can be benign or malignant. Treatment of malignant mesothelioma can involve surgery, radiation, and/or chemo
318
pneumoconiosis or black lung disease
is caused by inhaling coal dust and is common in coal miners. It causes inflammation and scarring of the lungs
319
Silicosis
caused by breathing in silica dust. This is a dust found in sandblasting operations and glass manufacturing facilities. IT causes scarring of the lungs and increases the risk for other lung diseases
320
asbestosis
this condition is caused when a person breathes in tiny asbestos fibers. Over time, this leads to scarring of the lungs and stiff lung tissue. It's often linked with construction and shipyard work. Patients have a high risk of developing mesothelioma
