What is an acute pulmonary edema considered?
Medical emergency
What causes pulmonary edema?
Anything that decrease the ability of the left ventricle to pump: MI, HTN, valvular disease, rapid arrhythmias
How should pulmonary edema be reasoned in terms of its effects on the heart>
This of it backwards: LV not pumping well, get stasis of blood from LV. Blood coming in from LA cannot get in. Back up in LA comes from the lungs. The pressure in the vessels of the lungs goes up. As pressure goes up the fluid builds up in capp and leaks into alveoli
