How frequently does air exchange occur during AGSM?

Air Exchange during Aerobic/Glycolic Stress Management (AGSM) is a crucial aspect of maintaining oxygen levels and ensuring the body can effectively manage stress during flight operations. The correct frequency of air exchange during AGSM is every three seconds. This timing is based on physiological considerations that balance the need for oxygen intake and carbon dioxide removal during physical exertion.

AGSM techniques involve specific breathing patterns that aid in stabilizing blood pressure and reducing the risk of G-induced loss of consciousness (GLOC), especially in high-performance aircraft maneuvers. By practicing air exchange consistently every three seconds, pilots can efficiently manage their oxygen levels and maintain better control over their physiological response to the forces experienced during flight. This frequency allows for optimal ventilation to support the body’s heightened demands, particularly under G-load conditions.

In contrast, the other options present frequencies that do not align with effective AGSM practices, either being too quick or too slow for optimal oxygenation during physical exertion.
