Metabolic consequences of garments worn to protect against post-spaceflight orthostatic intolerance.
Abstract
Astronauts have worn an inflatable antigravity suit (AGS) during Space Shuttle re-entry and landing to protect against hypotension and syncope, but ambulation with an inflated AGS requires significant effort and may prevent successful completion of an unaided emergency egress from the vehicle. NASA i...

Abstract
Although both garments successfully countered hypovolemia-induced orthostatic intolerance, the Kentavr provided protection by using lower levels of compression. Determining the optimal compression level required for protection of intolerance may improve crewmember comfort and decrease restrictions o...

Abstract
Training significantly improved (P < 0.05) RM strength after 6 wk of RMT measured in maximal expiratory pressures (RMT = 207.8 +/- 15.8 cmH2O; CON = 181.3 +/- 13.7 cmH2O) and maximal inspiratory pressures (RMT = -154.7 +/- 8.9 cmH2O; CON = -141.9 +/- 8.5 cmH2O). All other PFTs were unchanged. During...

Abstract
Compared with control, application of LBPP significantly reduced leg fluid volume (p<0.001) and increased neck circumference (p<0.001), both at 1 min and 5 min, and reduced UA-XSA after both 1 min (-0.15 cm2; 95% CI -0.23 to -0.09, p<0.001) and 5 min (-0.20 cm2; 95% CI -0.33 to -0.09, p<0.001).

Abstract
We concluded that the Kikuhime pressure sensor provides valid and reliable information and can be used in comparative clinical trials to evaluate pressure garments used in burn scar treatment. Secondly, elastic tricot garments in our study tended to have higher clinical pressures but both types of g...

Abstract
Pressure garments have been used prophylactically and to treat hypertrophic scars, resulting from serious burns, since the early 1970s. They are custom-made from elastic fabrics by commercial producers and hospital staff. However, no clear scientifically established method has ever been published fo...

Abstract
G protection in the 39 Gripen aircraft is provided by a full coverage anti-G suit, a pressure-breathing system, and anti-G straining maneuvers (AGSM). The purpose was to study (1) the interaction of pressure breathing and AGSM while wearing an anti-G suit; and (2) the G-protective properties of the...

Current recommendations state that pressure garments should be worn for up to 2 years for hypertrophic burn scars. Thermo-physiological properties of pressure garments were assessed by the thermo-physiological tests and a comparison of the fabric with a sportwool which is a single-jersey knitted fab...

Postpartum hemorrhage (PPH) is the main cause of maternal mortality. Yet, even though solutions have been identified, governments and donor countries have been slow to implement programs to contain the problem. While poverty and low educational level remain the underlying cause of PPH, the current l...

Five key themes surfaced: 1) GT as a concept is complex, and has different connotations for different users; 2) the term 'PC' likewise has a variety of meanings, and precise definitions are necessary to compare research results; 3) in examining the relationship between PC and GT, the roles of streng...

Pressure garments have been the mainstay of hypertrophic scar treatment since the 1970s. However, there are many problems associated with their use. This is the first in a series of papers on pressure garments that will review the literature published to date on the origins of pressure garments for...

We sought to determine to which pressure a full-coverage anti-G suit needs to be inflated in order to obtain the same stroke volume during a brief exposure to twice the normal gravity (2 G) as that at 1 G without anti-G suit inflation. Nine sitting subjects were studied at normal (1 G) and during 20...

Pressure breathing without a counter-pressure vest does not impair acceleration tolerance up to 9 G.
Abstract
Elimination of the COMBAT EDGE counter-pressure vest did not significantly reduce G-tolerance. During gradual onset G exposure, the mean G level reached with PBG was 8.4 G without the vest and 8.2 G with the vest. In comparison, 6.7 G was reached without PBG. Mean times at G with rapid onset G expos...
