Calculations
Temperature Corrections
The measured results are often corrected to the patient body tempera-
ture. The temperature corrected results more accurately reflect the in
vivo conditions. The EasyStat analyzer performs these calculations
using the following equations1:
∆ pH/ ∆ T = 0.0065 (7.4 - pH) - 0.0147
∆ log PCO2 = 0.019
∆ log PO2 = 5.49 x 10
- 11 (PO23.88) + 0.071
where: ∆ T is expressed in °C
PCO2 and PO2 are expressed in mmHg
pH is expressed in pH units
∆ T
∆ T 9.72 x 10
- 9 (PO23.88) + 2.30
