The purpose of this study was to make a trial production of an atmospheric-pressure hyperoxia controlled room (APHCR) and to verify its possibility for application of therapeutic exercise for pulmonary disorder patient and elderly. This room was with a vinyl chloride air tent, and hyperoxia gas generated system was used by a separate system of the polyimide membrane. This system could control O_2 concentration from atmosphere to 35% variably. Physiological changes were observed at rest and during exercise in different conditions of 20.9% and 30% O_2 concentration. SpO_2 in 20.9% O_2 condition decreased from 98.1% at rest to 96.9% at exercise, but SpO_2 in 30% O_2 condition was not changed between rest and exercise. Significantly higher physical working capacity (Watts) was observed at the same physiological strain(120bpm in heart rate) in a condition of 30% O_2 (73.3 Watts) compared with that in 20.9% O_2 (94.1 Watts). The results suggest that this trial production of APHCR can be applied to patients who can not perform whole body exercise to keep and improve their physical fitness due to pulmonary dysfunction or aging in atmospheric condition.
