일산화탄소 위해에 관한 연구 제1편 호흡분석에 의한 HbCO 포화도의 실험적추정

Abstract

The deleterious effects of carbon monoxide on the human body have long been known. Recently increasing incidences of carbon monoxide poisoning since the wide-spread uses of the briquette have been a serious problems on the view point of the public health in this country. The necessity of the devolopment of a rapid, accurate method of screening human subjeects for possible carbon monoxide poisoning cann't too overevaluted. The author undertook the confirmative experiment on the method of estimating bloodHb-CO contents by expired air analysis and discussed the appilcability of this method for the large scale survey work. For the CO analysis of expired air the carbon monoxide detecting tube (made in Korea) was used. 12 subjects were asked to breathe a mixture of CO to build up a measurable CO concentration. Consumption of the gas mixture (approximately 400 ppm) ranged from 95 to 100 liters. The collection of the expired air was made by such a way in which each subject was asked to hold his inhaled breath for 15 seconds before inflating the soft rubber balloon. Then the open end of the CO indicating tube inserted into the rubber stopper attached to syringe which drawed 50
