What condition refers to the heart's inability to effectively pump blood, often resulting in fluid buildup in the lungs?

The condition described is congestive heart failure (CHF), which is characterized by the heart's inability to pump blood effectively. When the heart cannot maintain adequate blood flow, it can lead to increased pressure in the heart and the pulmonary circulation. This results in fluid leaking into the lungs, causing pulmonary congestion and difficulty breathing. Symptoms of CHF can include shortness of breath, fatigue, and fluid retention, which may manifest as swelling in the legs or abdomen.

CHF can result from various underlying issues affecting the heart, such as previous heart attacks, long-standing high blood pressure, or damage to the heart muscle. Understanding this condition is critical for providing appropriate care and management strategies in emergency settings.
