Molecular sieve oxygen generating system: the argon question--a brief review
Aviation, Space, and Environmental Medicine
|September 1, 1979
Summary
Molecular sieve oxygen generating systems (MSOG) offer safer, more efficient aircraft oxygen supply. However, these systems also concentrate argon, raising questions about its physiological effects on aviators.
Area of Science:
- Aerospace Engineering
- Biomedical Engineering
- Environmental Science
Background:
- Molecular sieve oxygen generating systems (MSOG) are being evaluated to replace traditional oxygen supplies on aircraft.
- Onboard oxygen generation enhances flight safety and reduces logistical burdens.
- MSOG systems concentrate both oxygen and argon from engine bleed air, with typical outputs of 95% oxygen and 5% argon.
Purpose of the Study:
- To review existing literature on the physiological effects of argon as a minor component in breathing gas mixtures.
- To address concerns regarding the safety of breathing gas produced by MSOG systems.
Main Methods:
- Literature review of studies on argon in breathing gas systems (argon concentration <10%).
Main Results:
- Current MSOG systems produce breathing gas containing up to 5% argon.
- Limited data exists on the specific physiological impacts of argon at these concentrations in aviator breathing gas.
Conclusions:
- Further research is recommended to understand the physiological effects of argon before human compatibility testing of MSOG systems.
- Ensuring aviator safety requires comprehensive evaluation of argon's role in MSOG-generated breathing gas.
