A climber is coming down from the summit of Mt. Everest. At an altitude of 8,400m, he has a blood gas drawn while breathing ambient air as pa of a research project. The blood gas reveals pH 7.55, PCO2- 12, PO2 -30 and HCO3 -20. What does it demonstrate?
pH - 7.55 (alkaline) PCO2 - 12 (low) HCO3 - 20 (low) -Respiratory alkalosis * For every 10 mm | in CO2 -HCO3 to be | by 2 meq. * So PCO2 | ~ 30 mm Hg * HCO3 to be | by 2x3=6 * So 26-6 = 20 * But pH - | * So paially compensated compensation is paial because pH is not normalized(normal pH ranges 7.35-7.45)
Respiratory acidosis uncompensated
Respiratory alkalosis paially compensated
Respiratory alkalosis uncompensated
Respiratory acidosis paially compensated
