| Abstract: | This article finds out regression equation by using least square method, in order to rectify coefficients'errors in measuring PCO2 by pH/blood gas analyzer. The experiment proves that regression equation is a satified method of rectifying coefficients' errors. Data of the experiment also show, the more samples measured, the better accuracy. |
