What refers to the backup of fluid as a consequence of heart failure?

Pulmonary edema occurs when fluid accumulates in the lungs, which is often a direct result of heart failure. In heart failure, the heart is unable to effectively pump blood, leading to increased pressure in the blood vessels. This pressure can cause fluid to leak from the capillaries into the lung tissues and alveoli, resulting in pulmonary edema. Symptoms of this condition may include difficulty breathing, cough, and a feeling of suffocation, especially when lying down.

This situation is specifically linked to the impaired function of the heart, making pulmonary edema a prominent sign in patients with heart failure. Recognition and early management of pulmonary edema are crucial in emergency care settings to prevent more severe complications.
