Q: What is the target PETCO2 (Capnography) value during CPR?

Answer: Between 10 and 20 mm Hg.

If PETCO2 values less than 10 mm Hg or less measured after initiation of ACLS, it is associated with poor outcome. And, if value start rising abruptly, it indicates ROSC (Return Of Spontaneous Circulation).

PETCO2 is the maximum partial pressure of CO2 at the end a breath. It is about 36- 40 mm Hg in healthy adults.
