Effects of Wearing a Disposable Eye/Respiratory Protection (DERP) Mask inEnvironmental Extremes

摘要

The objective of this study was to evaluate three prototype DERP masks underconsideration for use by the U.S. Air Force. The evaluation included measurement of CO2 levels and breathing resistance inside these masks. Additionally, the thermal, physiological, and psychological effects of wearing the three masks during rest and exercise were measured during two 2-hr scenarios, once each under two different environmental conditions (heat and cold).
