Abstract : Baseline dynamic lung volume measurements were determined on four subjects seated upright or reclined, both with and without inflation of an anti-G suit (AGS). Additional measurements were made before and after exposing the subjects to double acceleration pulses using the NADC Dynamic Flight Simulator. During the acceleration exposures, the subjects were either seated upright or were reclined; they wore an inflated AGS and either did or did not perform the M-1 maneuver. Acceleration pulses lasted 20 or 40s, and ranged in magnitude from 3 to 7 G. The effects of body position, G-protective clothing, and acceleration exposure on pulmonary function measures derived from flow-volume loops are described.
