title: [Investigation of the physiological effect of heated heliox on the human external respiration parameters].
abstract: The investigation was aimed at studying and comparison of the physiological effects of heated heliox and air on the human breathing function. Tests involved eight human subjects aged 24 +/- 4 who breathed gas mixtures and air heated to 58 +/- 5 degrees C for 21 minutes. Effects were evaluated by spontaneous pneometry and forced expiration using equipment Master Screen VIASYS. Heated heliox and air equally caused phase-by-phase growth of external breathing parameters. Conduction of the trachea and main bronchial tubes appear to increase considerably due to heated heliox rather than air.
