Pulmonary edema is a fluid collection of the pulmonary arteries. Mostly caused by Cardiac problems like CHF or right ventricle hypertrophy etc can also be caused by large pnumonias. Tends to respond to diuretics so water pill. This will help urinate the fluid to resolve the edema but causes needs to be investigated. In my experience it is typically diagnosed by ECG, Echo, CT thorax w/ contrast and w/o contrast, CBC,CRP, VBG, and blood/Mucus cultures. If there is a pnumonia w/ plural effusion = culture thorethenesis. If all neg might preform bronscopy.

Acute pulmonary edema is the condition in which fluid accumulates in lung tissue which leads to impaired gas exchange. It presents as sudden onset of dyspnea, orthopnea, ankle swelling, basal crepts, raised JVP and cough with productive pink, frothy sputum. It is divided into 2 types: cardiac and non-cardiac causes of acute pulmonary edema. Cardiac causes of acute pulmonary edema include: Acute coronary syndrome, cardiac arrhythmia like atrial fibrillation, valvular heart disease, hypertension, cardiomyopathy and cardiac tamponade. The non-cardiac causes of acute pulmonary edema include: negative ionotropic medication, fluid over load, high output cardiac failure, anemia, thyrotoxicosis, sepsis, ARDS, pneumonia, trauma, toxins, non-compliance with medication and renal artery stenosis.
