Experimental observation of protection against acceleration induced arm pain by wearing pressure suit on upper body
Abstract：AIM:To observe pressure breathing for G(PBG) of subject in centrifuge runs or in flight and the character and degree of acceleration induced arm pain when wearing pressure suit on upper body,and to evaluate its protection. METHODS: Six subjects(male youth) were observed the character and degree of acceleration induced arm pain at 5.0,5.5,6.0,6.5 and 7.0 G for 15 s when they were exposured to the positive acceleration(+ Gz) and worn 65% extended coverage anti G suit(ECGS) and center pressure vest;after 10 min rest,the degree of remission were observed at 7.0 G for 15 s when objects worn pressure suit on upper body. RESULTS: Six objects accomplished the experience.Arm pain was developed at 6.0,6.5, 7.0 G, and probability and degree of pain increased with G titre by direct ratio.It was eliminated by using pressure suit on upper body at 7.0 G levels. CONCLUSIONS: The pressure suit on upper body is an effective method to protect against arm pain induced by + Gz and PBG.
