  • Chapter 17: Aeromedical Factors › Treatment of Hypoxia › Hyperventilation

    Hyperventilation Hyperventilation is the excessive rate and depth of respiration leading to abnormal loss of carbon dioxide from the blood. This condition occurs more often among pilots than is generally recognized. It seldom incapacitates completely, but it causes disturbing symptoms ... that can alarm the uninformed pilot. In such cases, increased breathing rate and anxiety further aggravate the problem. Hyperventilation can lead to unconsciousness due to the respiratory system’s overriding mechanism to regain control of breathing. Pilots encountering an unexpected…

    pressurized cabin altitudes. This takes into consideration the risk of aircraft decompression during flight. 8-1-3. Hyperventilation in Flight a. Hyperventilation, or an abnormal increase in the volume of air breathed in and out of the lungs, can occur ... subconsciously when a stressful situation is encountered in flight. As hyperventilation “blows off” excessive carbon dioxide from the body, a pilot can experience symptoms of lightheadedness, suffocation, drowsiness, tingling in the extremities, and coolness and react to them with even…

    controlled breathing in and out of a paper bag held over the nose and mouth. c. Early symptoms of hyperventilation and hypoxia are similar. Moreover, hyperventilation and hypoxia can occur at the same time. Therefore, if a pilot is using…

    factors can lead to inflight emergencies. Some important medical factors that a pilot should be aware of include hypoxia, hyperventilation, middle ear and sinus problems, spatial disorientation, motion sickness, carbon monoxide (CO) poisoning, stress and fatigue, dehydration, and heatstroke. Other…
