The use of warm heliox mixtures in rehabilitation after submaximal physical loads during production activity

: Thirty essentially healthy male gas-rescuers 21 to 53 years of age were treated with warm hellox following scheduled physically demanding repairs in open compressed air respiratory systems. Results of the actual test showed that a single heliox treatment makes for positive changes in the respiration and some psychophysiological parameters. The test allowed refinement of the warm hellox procedure of preventing extreme cooling, fatigue of and cardiovascular problems in gas-rescuers using respiratory systems at work place.
