Distinguishing Between Dynamic Altitude Breathing Threats to Improve Training

Abstract

Breathing related adverse physiological conditions are a prominent Warfighter pilot problem (Inspector General 2020). As a result of an investigation citing multiple types of adverse physiological conditions with various causes and symptoms (DoN 2017), there have been changes to training requirements to broaden the focus to include Dynamic Altitude Breathing Threat Training (DoN 2020). However, there remain questions about symptom definitions, distinctiveness, and response procedures that influence the content of this new training. In order to investigate the effects of different breathing conditions, the authors propose a between subjects design with adjustments to breathing conditions (i.e., restricted oxygen, restricted inhalation, restricted exhalation) using a mask on breathing device. Dependent measures include physiological data and pilot symptomology. The objective of this investigation is to inform awareness training for dynamic altitude breathing threats by validating instructional strategies and standard operating procedures for training implementation.Authors Note.
