Cardiovascular changes during and following 1-min exposure to +Gz stress.

Abstract

Magnitude and duration of cardiovascular responses following anesthetized dogs. During lower G forces (+1 to +3GZ), responses were variable. In most dogs during higher G forces (+4 or +5GZ), aortic pressure, cardiac output, left ventricular pressure, and dp/dt were dramatically compromised. These changes were observed whether the onset of the gravitational… (More)
