The effects of variations in the anti-G straining maneuver on blood pressure at +Gz acceleration.
Abstract
The increase in blood pressure provided by the standard AGSM is caused by both the contraction of the muscles of the lower body and by an increased intrathoracic pressure due to a respiratory straining (Valsalva) maneuver. This study examined the relative effectiveness and fatigability of the two components at +1 Gz and during +Gz acceleration in a human centrifuge. Brachial arterial pressure was recorded from a pressure-tip transducer in six …
