Antishock trouser inflation and pulmonary vital capacity

Inflatable External Upper and Lower Leg Compression Improves Stroke Volume and Peripheral Perfusion During Central Hypovolemia in Healthy Volunteers

“…Although ELC has already been routinely introduced since its first use in frontline emergency care, its utility in the management of critically ill patients is still a matter of debate. Previous publications using ELC in hemorrhagic shock have reported ELCrelated complications, such as respiratory acidosis or decreased pulmonary vital capacity, due to abdominal compartment compression [12][13][14][15]. For this reason, ELC with abdominal compression has received many criticisms, and current clinical applications have been mainly limited to leg compression in very specific clinical conditions, such as in obstetric surgery [5,6], and in cardiac or vascular artery bypass surgery [11,16,17].…”

Military anti-shock garment: Historical relic or a device with unrealized potential?

“…[37] On healthy volunteers, prolonged use of MAST reduced the volunteers' forced expiratory capacity by twelve per cent, vital capacity by thirteen per cent, functional residual capacity by eighteen per cent and tidal volume by twenty five percent reductions. [38] In the case of trauma patients, one study found that out of 25 trauma patients recruited in the respiratory function study which followed application of MAST, three patients suffered severe acidosis while the rest suffered mild acidosis.…”

Medical (military) anti-shock trousers--a short review.

“…Ransom & McSwain (1978) concluded that although mechanical pulmonary function A person of small stature experiencing more respiratory embarrassment than a subject of larger size although in all subjects there was a reduction in forced expired volume (FEV1) and forced vital capacity (FVC) at MAST inflation pressures of 40 and 60 mm (equal pressures in all compartments) (Table 5). It has recently been demonstrated than an increase in the size of the abdominal compartment leads to greater reduction in vital capacity than the standard MAST suit inflated to the same pressure (100 mm Hg) (McCabe et al, 1983).…”
