Hemodynamic effects of lateral tilt before and after spinal anesthesia during cesarean delivery: An observational study

tailieu.vn

A significant decrease was reported in mean arterial pressure, cardiac output, stroke volume, and systemic vascular resistance after SAB (in supine position). When performing left lateral tilting, there was an increase in cardiac output, heart rate, and mean arterial pressure. Conclusions: Changing position of full term pregnant woman after SAB from supine to left lateral tilted position results increased cardiac output and mean arterial pressure.

Chapter 033. Dyspnea and Pulmonary Edema (Part 3)

tailieu.vn

High Cardiac Output. Mild to moderate anemia is associated with breathing discomfort during exercise. Left-to-right intracardiac shunts may lead to high cardiac output and dyspnea, although in their later stages these conditions may be complicated by the development of pulmonary hypertension, which contributes to dyspnea. The breathlessness associated with obesity is probably due to multiple mechanisms, including high cardiac output and impaired ventilatory pump function..
