Following cardiac surgery, a 55 year old patient who has the following ABG results
pH 7.50 PaCO2 30 PaO2 62, HCO3 25,SaO2 92% Hb 14 BE +2.
Venous blood gas results are pH 7.39 PVC02 43 PVO2 37 SVO2 66%.
Calculate the C(a-v)O2
✓ ~~~ 5 vol %
calculate by calculating the CaO2 and CvO2
CaO2=(Hb x 1.34 x SaO2)/ PaO2 x0.003
