STUDIES OF RESPIRATORY FUNCTION FOLLOWING THORACIC AND THORACO-ABDOMINAL INJURIES: 1. PULMONARY COMPLIANCE, 2. ALVEOLAR VENTILATION, 3. INSPIRED GAS DISTRIBUTION
Abstract
A large mobile equipment cart especially designed for bedside studies has been assembled. The cart carries a spirometer integrated with apparatus for the determination of residual volume, inspired air distribution, pulmonary compliance and airway resistance. The cart and the apparatus are described in detail in the report. With the modified apparatus 29 subjects including normals, medical patients and traumatic chest and thoracic surgical patients have been studied; the results are tabulated in the report. The value of the individual tests for the investigation of acute chest injuries has been considered. Minute ventilation, tidal volume, nitrogen washout (single breath) curves, airway resistance measurements, and arterial oxygen saturation and carbon dioxide tension determinations are the most reliable and instructive procedures for the patient who is acutely ill and whose cooperation is limited. The complicated methods which measure pulmonary diffusing capacity and compliance require a steady-state and full cooperation and are suitable only after the clinical situation has been stabilized. They are then valuable aids for studying recovery of function and response to treatment. (Author)
