The process of blood gas and ph measurement involves preheating the arterial blood sample to normal body temperature 37 c prior to measurement of ph partial pressure of oxygen p o 2 and partial pressure of carbon dioxide p co 2 this ensures that results reflect in vivo temperature condition. Table 1 illustrates changes in blood gases during alpha stat and ph stat regimens as body temperature decreases from 37c to 30c table 1 an example of chang es in blood gases during alpha stat and ph stat regimens as body temperature bt de creases from 37c to 30c bt 37c bt 30c alpha stat pco 2 mmhg 40 after rewarming to 37c in blood gas . Temperature adjustment of blood gases and ph nov 09 2020 posted by yasuo uchida library text id 244239c8 online pdf ebook epub library 213 i 108 1 i 16 1966 a slide rule is described whose scales yield direct solutions of the following blood gas problems r the whole blood oxygen dissociation curve of man with vari able temperature ph and base excess 2 the effect of anaero important question . Too acidic or a blood ph of less than 735 alkalosis refers to having blood that knowledge of the effect of temperature on blood ph facilitates the understanding that the normal blood ph at 34 c is 745 at 37 c is 740 and at 40 c is 735 the effect of temperature on blood ph is rarely recognized clinically because the blood sample is always
