WebApr 28, 2024 · Afterload is increased due to an increase in systemic vascular resistance and aortic pressure increase. An increase in the afterload leads to a decrease in the heart's stroke volume and an increase in the end-systolic volume. This also indirectly affects the heart's cardiac output due to a reduction in the stroke volume of the heart. WebSeveral cardiovascular effects are seen with NIPPV in this setting. Decreased venous return occurs, and the increased intrathoracic pressure can decrease afterload and thereby increase cardiac output. Figure 48-9 details the interaction of the effects of NIPPV on the cardiopulmonary system.
