Physiological Effects and Operational use of Positive Pressure Breathing for G-protection
Journal Title: The Polish Journal of Aviation Medicine, Bioengineering and Psychology - Year 2016, Vol 22, Issue 3
Abstract
In preparation for the study, a MedLine search was conducted to review the status quo of positive pressure breathing for G protection (PPG). Aside from protective clothing, positive pressure breathing is one of the central building blocks of today’s anti-G measures. PPG has been covered by quite a few reviews. Since a definite review by Fong and Fan in 1997, a number of articles have been published. The topics covered reflect the effects of the new capabilities of 4th and higher generation fighter aircraft, such as the high onset-rates and the high sustained Gz-loads, and the need for further anti-G protection concepts. Furthermore, an old anti-G suit concept has been revived and emerged in recent publications. Positive pressure breathing for Gz protection is reviewed in comparison with anti-G-straining maneuvers (AGSM) with regard to pressure schedules and with respect to the composition of the inspired gas mixture. In addition, operational considerations are reviewed, covering aspects that contribute to the successful deployment of anti-G gear. Particular focus was put on the reduction of unwanted side effects of anti-G suits and PPG. The work available on this topic and new technology anti-G suits suggest more work to be done, in particular in the field of undesirable side effects on the health of the pilots.
