Flashcards in Alterations of Pulmonary Function Deck (69):
Abnormal Breathing patters are adjustments made by the body to minimize the work of Resp. muscles...List some of these.
What type of respirations are brought about by strenuous exercise or metabolic acidosis (DKA) characterized by a slightly increased ventilatory rate, very large tidal volume, and no expiratory pause?
Kussmaul Respirations (Hyperpnea)
These respirations are characterized by alternating periods of deep and shallow breathing w/apnea lasting 15 to 60 sec. & followed by ventilations that increase in volume until a peak is reached, after which ventilation (TV) decreases again to apnea?
This ventilation pattern is due to decreased alveolar ventilation caused by airway obstruction, chest wall restriction, or altered neurologic control. It causes Respiratory Acidosis & increased PaCO2.
This ventilation pattern is increased alveolar ventilation produced by anxiety, head injury, or severe hypoxemia. It causes decreased PaCO2 & leads to Respiratory Alkalosis.
This is a bluish discoloration of the skin caused by desaturation of hemoglobin, polycythemia, or peripheral vasoconstriction. Insensitive measure of disease possibly indicative of Pulmonary disease
Cardiac disease, Cold & Anxiety.
This anatomical finding is associated with diseases that interfere w/oxygenation of the tissues & it involves the fingertips.
This is a protective reflex that expels secretions and irritants from the lower airways.
This is expectoration of bloody mucus that can be caused by bronchitis, TB, abscess, neoplasms, and other conditions that cause hemorrhage from damaged vessels.
What types of Anatomical Respiratory issues can produce Chest pain?
-Inflamed Pleurae, Trachea, Bronchi, or Respiratory muscles.
This is a term for increased PaCO2 caused by a decrease in minute volume (Respiratory rate x Tidal volume).
Hypoxemia is a reduced PaO2 possibly caused by what 5 things?
1) Decreased FIO2
3) Diffusion abnormality
4) V/Q mismatch
This is caused by inadequate gas exchange or ventilation (PaO2 /=50mmHg & pH >/= 7.25)
Acute Respiratory Failure

-High = impaired perfusion w/normal ventilation (i.e., Pulmonary Embolism)
-Low = normal perfusion w/impaired or blocked ventilation (i.e., shunt)
This is a passage of fluid and solid particles into the lung, usu from impaired swallowing and coughing. It frequently results in pneumonitis and pulmonary infection.
This is the collapse of alveoli resulting from compression of the lung tissue or absorption of gas from obstructed alveoli?
This is abnormal dilation of the bronchi secondary to another pulmonary disorder, usu infection or inflammation.
This is a disorder due to an excessive amount of connective tissue in the lung. It diminishes lung compliance and may be idiopathic or caused by disease.
Inhalation of ________ gases or prolonged exposure to high concentrations of _______ can damage the bronchial mucosa or alveolocapillary membrane and cause inflammation or Acute Respiratory _______.

-Results in IgG AB production & cellular immune activation w/inflammatory response.
-Granuloma formation is common.
This is excess water in the lung caused by disturbances of capillary hydrostatic pressure, capillary oncotic pressure, or capillary permeability.
What's a common cause that increases the hydrostatic pressure in the pulmonary circulation & subsequent pulmonary edema?
Left sided Heart Failure
This results from an acute, diffuse injury to the alveolocapillary membrane and decreased surfactant production, which increases membrane permeability and causes edema and atelectasis.
This is a category of pulmonary disease characterized by airway obstruction that causes difficult expiration.
Obstructive pulmonary disease
What are some examples of obstructive pulmonary diseases?
2) Chronic Bronchitis
This obstructive disease causes episodic attacks of bronchospasm, bronchial inflammation, mucosal edema, and increased mucus production.
This is the coexistence of Chronic Bronchitis & emphysema.
This obstructive disorder causes airway obstruction resulting from bronchial smooth muscle hypertrophy and production of thick, tenacious mucus.
This obstructive disorder is where septal destruction and loss of passive elastic recoil leads to airway collapse and obstruct gas flow during expiration.
Emphysema in which septal deterioration is caused by __-________ or old age tends to be panacinar.
Emphysema in which septal deterioration results from _______ tends to be centriacinar.
These are the most common cause of short-term disability in the US, including rhinitis (cold), pharyngitis, & laryngitis.
Upper Respiratory Tract Infections
What are two serious lower respiratory tract infections, which occur most often in older adults and individuals w/impaired immunity or underlying disease?
Pneumonia & TB
Pneumococcal pneumonia is an acute lung infection resulting in an inflammatory response with what four phases?
2) Red hepatization
3) Gray Hepatization
Viral pneumonia is an acute, self-limiting lung infection usu caused by?
TB is a lung infection caused by what organism?
In TB the inflammatory response isolates colonies of ______ by enclosing them in tubercles and surrounding the tubercles with ______ tissue.
What are the two possibilities that may occur during Bacilli invasion (TB)?
1) Remain Dormant
2) Recurrence of active disease
These are circumscribed areas of destruction of lung parenchyma w/suppuration usu resulting from aspiration pneumonia?
Pulmonary vascular diseases are caused by what?
2) HTN in pulmonary circulation
This is an occlusion of a portion of the pulmonary vascular bed by a thrombus, tissue fragment, or air bubble.
Depending on the size & location of the PE, the embolus can cause what to happen?
1) Hypoxic vasoconstriction
2) Pulmonary Edema
4) Pulmonary HTN
How is pulmonary HTN defined?
Pressure in pulmonary artery greater than 5-10 mmHg of normal
Pulmonary HTN can be caused by what?
1) Elevated Left Ventricular pressure
2) Increased blood flow through the pulmonary circulation
3) obliteration or obstruction of vascular bed
4) Active constriction of vascular bed produced by hypoxemia or acidosis
This is right ventricular enlargement caused by chronic pulmonary HTN & can progress to RVF if not reversed?
____ cancer is most common in men and represents about 1% of all cancers. In the most common cell type, ________ cell, metastasis is rare when lesions are Dx & Txt early.

What's the most common symptom associated w/pleural effusion?
This is an infected pleural effusion via presence of pus in the pleural space.
This is a pleural effusion of watery fluid that diffuses out of capillaries beneath the pleurae due to cardiovascular diseases that causes high blood pressure, kidney or liver disease that disrupts plasma protein production...
This type of effusion contains fluid rich in protein that migrates out of capillaries due to infection, inflammation, or malignancy of pleurae that stimulates MC's to release biochem. mediators that increase capillary permeability.
This pleural effusion is fluid of chyle (lymph & fat) that's dumped by lymphatic vessels into the pleural space instead of passing form the GI tract to the Thoracic duct via traumatic injury, infection, or disorder that disrupts lymphatic transport.
