frothy sputum is late sign

Pulmonary edema: feels like they are drowning on the inside. Intubate and vent so they
can breathe.

Right-sided heart failure ✅"cor pulmonale", the right ventricle has the oxygen depleted
blood and is supposed to move it to the lungs. Instead, it pools back out through the
