In cardiogenic causes increased pulmonary capillary pressure occurs due to left ventricular failure. While in non-cardiac causes the cause is injury to lung parenchyma occurs. cardiac causes of pulmonary edema include LVF and RVF. A left ventricular failure presents as: respiratory distress, tachypnea, bilateral basilar crepts, cardiac wheeze, tachycardia, displaced apex beat and prominent third heart sound. In RVF signs of edema present as: right heave, raised JVP, hepatomegaly and peripheral edema.
