About

This video explains how the heart and lungs work together, especially during positive pressure ventilation. It describes the differences between mechanical and spontaneous breathing, focusing on preload, afterload, and contractility of the heart. Positive pressure can affect blood flow to the heart and change how well it pumps blood. The article also covers right and left ventricular functions in different conditions like asthma or muscular dystrophy. It highlights that while positive pressure helps some patients breathe better, it requires careful management to avoid problems with heart function when removed.
