Venous PH


Q: During or immediately following CPR, and in hemodynamic shock which PH is more worthwhile to follow ?


A:
Venous PH

During shock state, venous blood is a more accurate reflection of metabolism in tissues. It may be of benefit to follow the trend in venous PH to measure the improvement of shock following CPR and hemodynamic instability.
