Week 13 - Thoracic and Pulmonary Sx, Cardiac Sx Flashcards
Arterial blood gas (ABGs)
blood test that determines CO2 and O2 saturation, pH, and other important parameters of respiration and oxygen perfusion
Blebs
areas of over distention in lung tissue
Closed chest drainage
system of removing air or fluid from thoracic cavity and restoring negative pressure so lugs will expand properly after thoracic sx or penetrating trauma to chest wall
Diffusion (oxygen)
molecular passage of O2 across the alveoli and into the bloodstream
Dyspnea
difficulty breathing
Empyema
pus-filled area of the lung
Expiration
exhalation; act of breathing out
Hemoptysis
blood sputum or bleeding arising from the respiratory tract
Hemothorax
presence of blood in the thoracic cavity or between the pleural sac and lungs
Hypoxia
lower than normal perfusion
Inspiration
inhalation; act of taking a breath
Perfusion (oxygen)
distribution of O2 to tissues
Pneumothorax
air in the chest cavity; prevents lungs from expanding any may displace mediastinal structures
Pulmonary function test (PFTs)
tests performed to measure function and strength of the pulmonary system
Ventilation
process of inflating and deflating lungs during breathing
Apnea
cessation of respiration
Hyperventilation
abnormally fast rate of respiration
Hyperpnea
excessively deep respiration
Tidal volume
amount of air exhaled during normal respiration
Bronchoscopy
endoscopic examination trachea and bronchi
