Prognozing of the Resistance to Hypoxia in Military Pilots by Cardiovascular and Respiratory Parameters.

摘要

The effect of hypoxic hypoxia on the autonomic cardiovascular response pattern and the prognosis of resistance to hypoxia were determined after exposure to hypoxic hypoxia in barochamber at simulated altitude 5000 m in 21 military pilots. Cardiovascular: heart rate variability (HRV) measures heart rate systolic and diastolic blood pressure and respiratory parameters: arterial oxygen saturation were examined in pre-hypoxic and post-hypoxic exposure. Although mean values of cardiovascular and respiratory parameters corresponded to referents, hypoxia caused significant effect on HRV measures, diastolic blood pressure, and arterial oxygen saturation.
