Use of morphine sulfate in acute pulmonary edema reduces pulmonary venous return (preload reduction). The beneficial hemodynamic effect is probably due to anxiolysis, with a resulting decrease in catecholamine production and decrease in systemic vascular resistance.
However, it may also contribute to a decrease in cardiac output that may lead to a need for ICU admission and endotracheal intubation.

Pulmonary edema is an abnormal build up of fluid in the lungs, which leads to swelling. Usually pulmonary edema occurs when there is unstable angina or heart failure. The initial treatment for angina is nitroglycerin but when the symptoms are not relieved then Morphine Sulfate is the next drug of choice

Because it's a smooth muscle relaxant. It decreases myocardial oxygen demand and it reduces preload on the heart. It also reduces anxiety in the patient. Good link below.

Vasodilation causing decreased venous return to the right heart, lowering filling pressure and ultimately lowering left atrial pressure.

If you want to make sure they visit the ICU...it's a great idea :(
Seems like we often end up with pts who have a decreased cardiac output, then we have to tube them...
