Why does pediatric pneumonia lead to right heart failure?

Pediatric pneumonia can lead to right heart failure because, in severe cases, the disease impairs oxygen exchange in the body, causing hypoxia and increasing the functional load on the heart. Therefore, if severe pneumonia persists, it may result in heart failure. Pediatric pneumonia affects the body's ventilation function, preventing sufficient oxygen intake, leading to decreased blood oxygen levels and reduced metabolic function in various tissues and organs. In particular, the heart must compensate by increasing heart rate and workload to meet the body's demand for blood supply.
