Pulmonary edema is a medical condition characterized by fluid accumulation in the lungs, leading to difficulty breathing and reduced oxygen levels in the blood. This condition can be caused by various factors such as heart failure, pneumonia, kidney failure, high altitude, or certain medications. Pulmonary edema can be a life-threatening condition if not treated promptly and properly. Treatment usually involves addressing the underlying cause, such as administering diuretics to remove excess fluid from the body or providing supplemental oxygen to improve breathing. Research in this area focuses on understanding the mechanisms of pulmonary edema, developing more effective treatments, and improving patient outcomes.
