WebOct 31, 2013 · CPAP provides additional benefits to patients suffering from the acute effects of cardiogenic pulmonary edema by reducing both the preload and afterload, thereby improving the body’s hemodynamics. WebDecreased afterload—anything that enhances the ejection of blood out of the heart will decrease both the end-systolic ventricular volume and the end-diastolic ventricular volume. This decreases the preload.
