Book excerpt: 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 an oxygen mask for use with the Personal Helicopter Oxygen Delivery System (PHODS) for potential use by U.S. Army helicopter aircrew. The mask was tested on pilot volunteers at altitude to determine efficacy. The mask and PHODS was able to maintain aircrew blood oxygen at acceptable levels up to and including 18,000 feet.
