What increases survival in COPD patients
Oxygen, smoking cessation
Pathophysiology behind ARDS, diagnostic criteria
Decreased lung compliance, increased WOB, severe V/Q mismatch- severe hypoxemia through intrapulmonary shunting, increased hypoxia pulmonary vasoconstriction- RV afterload, acute PHTN.
