Effect of type WIYIS-6/90 plateau oxygen generating vehicle on high altitude spot / 医疗卫生装备

ABSTRACT

Objective To evaluate the effect of type WIYIS-6/90 plateau oxygen generating vehicle on the high altitude spot. Methods Totally 20 male soldiers during field training at 4 280 m altitude were involved in this trial. They were given administration of oxygen inhalation at 2 L/min by nasal cannula. Blood pressure, heart rate, blood oxygen saturation, vital capacity, left and right hand strength, digit span and discriminative reaction time were detected before and after oxygen inhalation for 20 minutes and finished for 10 minutes. Results After oxygen inhalation for 20 minutes, blood oxygen saturation, vital capacity, left and right hand strength, digit span and correct times increased and heart rate decreased compared with before oxygen inhalation (P<0.05,or P<0.01).Stopping oxygen inhalation for 10 minutes,vital capacity and right hand strength increased and response time decreased(P<0.05,or P<0.01).Conclusion Using type WIYIS-6/90 plateau oxygen generating vehicle for oxygen supply at high altitude can improve brain-body function and promote work ability.
