Detailed explanation-1: -Lung and airway diseases such as asthma, cystic fibrosis, COPD, and interstitial lung diseases. Fluid buildup in the lungs or pulmonary embolism (a blood clot in your lungs) Infections in your brain or spinal cord (such as meningitis ), lungs (such as pneumonia), or airways (such as bronchiolitis)
Detailed explanation-2: -In emphysema, the inner walls of the lungs’ air sacs (alveoli) are damaged, causing them to eventually rupture. This creates one larger air space instead of many small ones and reduces the surface area available for gas exchange.
Detailed explanation-3: -Emphysema, the fourth leading cause of death in the United States, affects the walls of the millions of tiny air sacs in the lungs, which become inflamed and lose elasticity, causing the bronchioles to collapse.
Detailed explanation-4: -Type 1 (Hypoxemic )-PO2 < 50 mmHg on room air. Usually seen in patients with acute pulmonary edema or acute lung injury. Type 2 (Hypercapnic/ Ventilatory )-PCO2 > 50 mmHg (if not a chronic CO2 retainer). Type 3 (Peri-operative). Type 4 (Shock)-secondary to cardiovascular instability.
