Ph-stat测水解度

WebMay 15, 2024 · The practitioner may use a rudimentary estimate of the effect of temperature on blood gas values with the following simple equations: For each 1°C decrease in body temperature below 37°C, the PO2 will decrease by 5 mmHg, PCO2 will decrease by 2 mmHg, and pH will increase by 0.012. Arterial CO2 increases by 4.6% for each 1°C over 37°C.
