Determines the corrected partial oxygen pressure (pO2) from the barometric pressure at current elevation in mmHg for EPOC Blood Gas Analyzers when running aqueous solutions.
Formula:
Corrected PO2 = PO2 reading + (2mmHg + 6% PO2 reading) x (760mmHg – Barometric pressure)/100mmHg
Principle:
PO2 readings will decrease by 2mmHg + 6% per 100mmHg barometric pressure under 760mmHg. Therefore, before comparing the gas readings with the published value assignments, the PO2 readings need to be corrected.
