Q

describe what exactly “aerosol therapy” is about

A

aerosol therapy use of an aerosol for respiratory care in the treatment of bronchopulmonary disease. The major purpose of this is the delivery of medications or humidity or both to the mucosa of the respiratory tract and pulmonary alveoli. Agents delivered by aerosol therapy may act in a number of ways: (1) to relieve spasm of the bronchial muscles and reduce edema of the mucous membranes, (2) to render bronchial secretions more liquid so that they are more easily removed, (3) to humidify the respiratory tract, and (4) to administer antibiotics locally by depositing them in the respiratory tract

25
why is the purpose of having serous fluid between the lungs pleural membranes
The main function of pleural membranes is to hold the two lungs within their pleural cavity. These membranes do this while ensuring that the lungs remain expanded during out-breaths and can move along each other smoothly during the process of breathing.
26
when teaching patients about their oxygen use why do we need to stress the importance not smoking, candle use, ungrounded electrial
Oxygen tanks are extremely dangerous in a sense that it can combust no smoking, no wool hoodies.
27
what is the use of accessory muscles indicate
in labored breathing, the use of muscles other than the diaphragm and intercostals. the sternocleidomastoid, spinal, neck, and abdominal muscles and even the platysma, may be used. their use is a sign of an abnormal or labored breathing pattern.
28
what exactly does the pulse oximetry tell us? how does it work?
it tells us the amount of oxygen circulating in the blood. It's a red light
29
what do ABG's tell us
An arterial blood gas (ABG) test measures the acidity (pH) and the levels of oxygen and carbon dioxide in the blood from an artery
30
what age related changes happen to the respiratory system
- lung capacity decreases - ability to cough is less effective - SOB on exertion - airway size decreases - kyphosis
31
define dyspnea
difficult breathing
32
define valsalva maneuvers
the action of attempting to exhale with the nostrils and mouth, or the glottis, closed. This increases pressure in the middle ear and the chest, as when bracing to lift heavy objects, and is used as a means of equalizing pressure in the ears.
33
define ventilation
Ventilation (breathing) is the mechanical process of respiration that moves air to and from the alveoli.
34
define perfusion
oxygenation. the passage of fluid through the circulatory system or lymphatic system to an organ or a tissue, usually referring to the delivery of blood to a capillary bed in tissue.
35
define inspiration
Breathing air in is called inhalation or inspiration
36
define vasovagal response
A sudden drop in heart rate and blood pressure leading to fainting, often in reaction to a stressful trigger. bradycardia
37
define eupnea
Normal respiration
38
define orthopnea
Difficulty breathing while lying down, relieved by sitting upright (orthopneic position)
39
define hyperpnea
Increase in depth of breaths; maybe increase in rate (no feeling of increased respiratory effort
40
define productive cough vs non productive cough
A cough is considered productive when it brings up and removes secretions, such as sputum and mucus, as well as exudates from a lung infection. A cough is considered nonproductive when it is dry and irritating and no secretions are produced.
41
define TCDB
Turning, Coughing, and Deep Breathing
42
define pulmonary function test (PFT)
The pulmonary function test (PFT) measures how much air a client inhales (inspiration) and exhales (expiration) in one breath and assesses the client’s general respiratory status.
43
define postural drainage
Postural drainage uses position and gravity to drain secretions and mucus from the individual’s lungs
44
define adventitious breath sounds
an abnormal lung sound
45
define respiratory excursion
excursion is when the diaphragm is moved up and the lungs can't get full expansion
46
define IPPB
intermittent positive pressure breathing (IPPB). IPPB is used almost exclusively for children with cystic fibrosis
47
define thoracentesis
removal of fluid from the thoracic cavity
48
define bronchoscopy
Bronchoscopy is an invasive procedure in which a bronchoscope (a lighted endoscope) is advanced through the pharynx into the trachea and bronchi. The purpose of this test may be to observe lung tissue, obtain a biopsy or bronchial washings, remove mucous plugs or foreign objects, or determine the location and extent of a mass (tumor).
49
define purse lip breathing
Pursed lip breathing (PLB) is a breathing technique that consists of exhaling through tightly pressed (pursed lips) and inhaling through the nose with the mouth closed. helps control respiratory rate
50
unless ordered, how much oxygen are we allowed to give to the patient and why
2L/min. standing order.
51
where does gas exchange take place, through what process
in the lungs between the alveoli and a network of tiny blood vessels called capillaries, which are located in the walls of the alveoli
52
describe exactly why we do the Airway, Breathing, and Circulation, disability and safety (ABCDE's)m in this order
Airway, breathing, and circulation, therefore work in a cascade; if the patient's airway is blocked, breathing will not be possible, and oxygen cannot reach the lungs and be transported around the body in the blood, which will result in hypoxia and cardiac arrest. Ensuring a clear airway is therefore the first step in treating any patient; once it is established that a patient's airway is clear, rescuers must evaluate a patient's breathing, as many other things besides a blockage of the airway could lead to an absence of breathing.
53
why is it so very important to make sure to give patients their ordered pain medication prior to starting any therapy such as ambulating
patients will ultimately be in some sort of pain following any movement post surgery.
54
How are PFT's done
LUNG FUNCTION TEST. Using a spirometer, client takes in maximal inhalation and then exhales forcefully and as rapidly as possible. Room air, helium, or 100% oxygen may be used. Peak flow: blowing outward hard
55
why is it so very important to stress the importance of NOT smoking at least 6-8 hours prior to its doing their pFT
Smoking before will alter the test results
56
describe what would you hear with each lung: coarse crackles stridor wheezing
crackles: sounds like a loud velcro being torn apart stridor: Stridor is a high-pitched wheezing sound caused by disrupted airflow wheezing: a sort of continuous sound, with a buzzing quality to it
57
describe what normal respirations would look like in your patient
Normal respirations is a count between 12-20 RPM. Note no distress while inhaling. The stomach should not be moving
58
what is the appropriate technique and supplies used to obtain a throat culture
cotton-tipped applicator and applied to a slide or culture medium
59
describe what a pt with a partial airway obstruction would be doing
The signs of partial airway obstruction includeunusual breath sounds, skin discoloration(cyanosis), or changes in breathing pattern. Theconscious patient will usually make clutching mo-tions toward the neck, even when the obstructiondews not prevent speech. For the conscious pa-tient with an apparent partial obstruction, en-courage him or her to cough
60
what types of oxygen masks are available for all types of patients
``` nasal cannula simple face mask partial facial mask nonrebreather venturi mask face tent ```
61
describe reasons why we might use a venturi mask vs a regular disposable mask
for the highest o2 quality.
62
what is the initial set up for 02 therapy via mask or nasal cannula
2L/min
63
your patient is receiving IPPB what are we constantly monitoring for during procedure and why?
ability to breath better
64
post bronchoscopy: what are you monitoring for and why
gag reflex. we use numbing ointment in the throat and patients can aspirate on food or water if they don't have it. lung sounds and respirations
65
What is the equipment and prep for insertion of a chest tube, as well as pt teaching we do?
``` insertion tray tube local anesthetic suturing supplies sterile gloves sterile water gauze suction setup and tubing chest tube collection system vaseline gauze silk tape ```
66
What is the chest tube care after insertion?
xray for placement, vitals, keep below chest level, cough and deep breath q2h, loc, lay on unaffected side
67
Why would a PCP request a chest X-Ray before and after placement of the chest tube?
to check and make sure the tube is in the right spot.
68
What type of mask would be used if your pt had pulmonary TB?
N95
69
What mask is used to deliver the highest concentration of oxygen?
venturi mask
70
Why encourage TCDB if you hear fine crackles during your pts assessment. Why?
will help loosen up phlegm in the lungs. could just be stagnant.
71
What does a Mediastinal shift have to do with a Thoracentesis?
The lung on the affected side collapses, and pressure on the mediastinum shifts the thoracic organs to the unaffected side of the chest, placing pressure on the opposite lung as well. Ventilation is severely compromised, and venous return to the heart is impaired. Hypotension and distended neck veins are evident as tension pneumothorax affects venous return and cardiac output. The mediastinal shift also displaces the trachea toward the unaffected side.
72
What supplies and equipment would be needed for a Thoracentesis?
``` insertion tray tube local anesthetic suturing supplies sterile gloves sterile water gauze suction setup and tubing chest tube collection system vaseline gauze silk tape ```
73
When removing a chest tube what do we instruct the pt to do PRIOR to removing and why?
they will take pain medication half hour prior to procedure. instruct client to take a deep breath, exhale, and bear down. valsalva maneuver. apply airtight petroleum jelly gauze dressing
74
If the tubing comes undone from the chest tube collection system what action do we do immediately and why?
If a chest tube is completely dislodged, cover the site immediately with a sterile gauze dressing. If you can hear air leaking out of the site, make sure the dressing is not occlusive. If it is, it can cause a tension pneumothorax.
75
How does the skin feel on a pt whose chest tube is leaking into his tissues?
subq emphysema crepitus. like bubble wrap
76
Airway suctioning for ADULTS is no longer than ------------- why?
10 seconds at a time followed by 1 minute intervals 3 times only.
77
What would you expect to see happen in the pt with a vasovagal experience?
BP and HR increase Abrupt fall of BP and HR Supine on floor
78
Why should pts cough deeply a AFTER postural drainage?
allows for air to fully expand the lungs
79
When is the best time to perform postural drainage
before eating to prevent vomiting up food.
80
How do we know that postural drainage is actually effective?
when patients can breath effectively and or cough up loose phlegm.
81
If your pt is unconscious what position should you place him/her in to facilitate drainage and avoid aspiration? Why?
semi fowlers on their side. allows fluid to leave the mouth | so they don't aspirate
82
Explain pulmonary circulation.
Pulmonary circulation is the portion of the cardiovascular system which carries deoxygenated blood away from the heart, to the lungs, and returns oxygenated (oxygen-rich) blood back to the heart.
83
What are the respiratory centers of the brain?
medulla and pons
84
Respiratory disorders using a CT scan.
allows you to see exactly where a problem is at
85
What is respiratory excursion?
Diaphragmatic excursion is the movement of the thoracic diaphragm during breathing
86
Difference between ventilation and respiration
respiration is an automatic process that allows for oxygen to be gained into red blood cells, through diffusion via either passive or active transport. ... The physical movement of pulling/pushing air throughout the body is breathing/ventilation
87
diffusion
gas exchange. alveoli
