Characterization of Peak Inspiratory Flow and Alveolar Ventilation during MaximalArm Crank Exercise With and Without Inspiratory Airflow Resistance

摘要

The Army requires an accurate understanding of ventilatory requirements forcombat vehicle crewmen. This study was conducted to measure 3 specific ventilatory parameters in exercising soldiers so that (1) Army engineers would be able to optimize design specifications for tank air delivery systems, (2) strategists would be better able to develop doctrine regarding use of the disconnected protective mask apparatus (Mission Oriented Protective Posture Gear), and (3) military planners would be better able to predict carbon monoxide hazards for tank crewmen. The objective of the current protocol was to measure maximal human ventilatory parameters during upper body exercise to extend the application of observations made during a previous field study of tank crewman's requirements. This study will provide measurements of peak inspiratory flow V sub i peak), estimates of alveolar ventilation (v sub A), and understanding of respiratory muscle fatigue.
