Pulmonary edema

Non-cardiogenic Pulmonary Edema

Etiology

Acute respiratory distress syndrome (ARDS) Such as
- sepsis, pneumonia,
- gastric aspiration,
- blood transfusion,
- pancreatitis,
- multisystem trauma or trauma to the chest wall,
fractures with fat embolism, burns, or head injury
High altitude pulmonary edema (HAPE)
Neurogenic pulmonary edema
Opioid overdose
Salicylate toxicity
Pulmonary embolism
Reexpansion pulmonary edema
Reperfusion pulmonary edema
Transfusion-related acute lung injury (TRALI)

Cardiogenic Pulmonary Edema

Cardiogenic pulmonary edema (CPE) is defined as pulmonary edema due to increased capillary hydrostatic pressure secondary to elevated pulmonary venous pressure caused by left heart disease Etiology Disorders that increase pressure in the left side of the heart and pooling of blood can cause cardiogenic pulmonary edema

Etiology

Coronary artery disease with left ventricular failure (myocardial infarction)
Congestive heart failure: left ventricular volume overload
Cardiomyopathy
Valvular heart diseases on the left side of the heart (stenosis and regurgitation)
Cardiac arrhythmias
Right to left shunts
