Are pulmonary edema and a pulmonary embolism the same?

No. Pulmonary edema refers to fluid in the lungs, most commonly as a result of a failing heart. Pulmonary emboli are blood clots that form somewhere in the body (usually the legs) and travel to the lungs.
No. The lung's job is to bring oxygen to blood and remove carbon dioxide from blood. The blood supply is the pulmonary artery. If there is a plug (embolism) in that artery, the blood cannot reach oxygen-rich lung, causing "dead space." with edema, the lung is flooded with fluid so oxygen is blocked from reaching artery, causing "shunt." basically, edema is a lung problem, embolism is vessel problem.
Pulm edema vs PE. No pulmonary edema is in essence water in the lungs, pulmonary emboli is clots.
No they are not. Pulmonary edema is "fluid" inside your lungs. This is usually caused by disfunction of the left side of the heart. Pulmonary emboli is a blood clott in the blood vessels of your lung. The problem is that clinically, the patient may feel the same symptoms of dyspnea, tiredness, fatigue, cough. Chest pain and unilateral peripheral edema tends to be associated more with pulmonary emboli.
