Exchange of gases between inhaled air in alveoli and blood in pulmonary capillaries
Exchange of gases at cellular level between tissue cells and blood in systemic capillaries
Initially slow, shallow respirations that increase in rapidity and depth, then gradually decrease respirations the stops for 10-60 seconds
Prevents negative pressure within pleural space from pulling air in/tidaling of water
Most common airway obstruction which bronchiole blocked with secretions/alveoli distal collapse
Used to prevent clots from traveling from lower extremities to heart, lungs, and brain
Rapid fluid shift from plasma to interstitial and alveoli causing impaired gas exchange
Inflammed bronchial tree with excessive mucus leading to chest wall distention, and increased infections
Condition where airways become fibrotic, lose elasticity, and result in narrow lumen leading to barrel chest, hypercapnia, and hypoxia
Chronically dilated bronchi caused by pulmonary TB, chronic URI, or childhood infections due to cystic fibrosis
No communication between external environment and pleural space such as with broken rib
Direct communication between external environment and pleural space such as with gun shot or knife
Air enters pleural space on inspriation but unable to exit on expiration caused by mechanical ventilation or central lines
