title: The effect of the halovest and body position on pulmonary function in quadriplegia.
abstract: Pulmonary function (vital capacity) was measured in ten quadriplegics and ten normal subjects in the following situations: supine, sitting, supine with a halovest, and sitting with a halovest. When changing from the supine to sitting positions, vital capacity decreased in the quadriplegics and increased in normal subjects. The halovest significantly reduced the vital capacity in normal subjects, but had much less of a detrimental effect in quadriplegics. As a result of this prospective, controlled study, we conclude the following: (a) the compromised state of pulmonary function in quadriplegics is not a contraindication for the use of a halovest, (b) the halovest causes a significant (p less than 0.01) restriction in vital capacity in able bodied subjects, and (c) when tenuous pulmonary function exists in a quadriplegic, pulmonary mechanics are better in the supine position.
