- 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
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.
