Hemodynamic effects of continuous positive airway pressure as assessed by doppler echocardiography

Conclusions: Continuous positive airway pressures of 10 and 15 cm H2O generated reductions in right ventricular preload without changing either left ventricular preload or left ventricular afterload. There was also a decrease in cardiac output due to a reduction in heart rate. A strong correlation was observed between the mitral velocity-time integral and both stroke volume and cardiac output.
