급성일산화탄소중독에 있어서 호기분석에 의한 Carboxyhemoglobin 포화도의 추정

Abstract

A study was done to estimate the blood HbCO level by measuring the CO concentration in expired air of 47 acute CO poisoning patients at emergency room of Seoul Adventist Hospita l. The results are summarized as follows; 1. The correlation between CO concentration in expired air and blood HbCO level is shown by the regression equation of (% HbCO) = 10.315+0.203 (ppm CO) with its correlation coefficient 0.835 and standard error 5.6. 2. The correlation coeciffient in the cases having CO concentration below 100 ppm is 0.827 and that above 100 ppm, 0.573. It shows the higher correlation coefficient in lower CO concentration cases 3. Difference by sex is statistically insignificant. Close correlation is observed as age is increased. Another close correlation is observed as consciousness level at emergency room is poor. 4. It could be concluded that the estimation of blood HbCO level by measuring CO concentration in expired air is a suitable method for rapid and accurate assessment of CO poisoning.
