Abstract:

Positive pressure breathing PPB term emergency protection against hypoxia in the event of cabin depressurization in military aircraft operating at altitudes exceeding 40,000 feet. PPB, however, causes significant disturbance to the normal function of the respiratory and circulatory systems, thus limiting the level and duration of pressure breathing that can be tolerated. The adverse effects of PPB can be lessened by the use of counter-pressure garments, which apply an external pressure to the surfaces of the trunk and the lower limbs. We investigated the potential benefits of increased lower limb counter-pressure as a measure to optimize cardiovascular function during PPB.
