NaHCO3 administration during CPR
Should not be used until other proven interventions (ET tube, defibrillation, cardiac compression, adrenaline)
Estimated that this interventions required at least 10 min.

Guideline for NaHCO3 administration during CPR
Known preexisting metabolic acidosis with or without hyperkalemia
Known hypercalcemia
1 mEQ/kg then no more than half for subsequent dose
No more frequently than every 10 min
Postresuscitation phase, guideed by arterial blood gas

Alternate buffer agents during CPR
THAM (tromethamine), potent amine buffer
DCA (Dichloroacetate), stimulating pyruvate dehydrogenase (oxidative enzyme in step of lactate to pyruvate)
However, no alternate buffer agents improve survival during CPR
