Web25 de abr. de 2024 · Just prior to systole, the IABP is deflated, creating a void where the inflated balloon was, thus increasing forward flow into the aorta and to the periphery (b). Table 21.3 Hemodynamic effects of IABP therapy. Decreased left ventricular afterload. Decreased aortic SBP. Decreased pulmonary capillary wedge pressure. WebIncreased preload increases stroke volume, whereas decreased preload decreases stroke volume by altering the force of contraction of the cardiac muscle. The …
WebAfterload: Afterload describes the resistance that the heart has to overcome, during every beat, to send blood into the aorta.These resistive forces include vasoactivity and blood viscosity. Cardiac Index (CI): The amount of blood pumped by the heart, per minute, per meter square of body surface area. Cardiac Output (CO): The volume of blood pumped …
