A Physiological and Human Factors Evaluation of a Novel Personal Helicopter Oxygen Delivery System
Abstract
In current U.S. Army operations, rotary-wing aircrew can be repeatedly exposed to moderately high altitude (up to 18,000 feet pressure altitude), making hypoxia, and its performance effects, a real hazard. The United States Army Aeromedical Research Laboratory (USAARL) was tasked by the Product Manager Air Warrior to evaluate a portable oxygen system for potential use by U.S. Army helicopter aircrew. The system described below provided capability for oxygen production, charging of the portable system, as well as in-flight use by aircrew. The system was tested for its compatibility with current Aircrew Assemblies, Night Vision Goggles, aircrew duties, and emergency egress. The system was also tested on pilot volunteers at altitude to determine efficacy. The Personal Helicopter Oxygen Delivery System (PHODS) was able to maintain aircrew blood oxygen at acceptable levels up to and including 18,000 feet.
