Capnography for ROSC patients

There was a case recently where a paramedic was working a code on a patient in PEA. During the code, the EtCO2 of the patient rose from 12mm to 27. The medic correctly assumed that his patient was a ROSC patient. He stated so to the ED staff when he turned the patient over to them. The doctor ignored the medic, and stated that the increased EtCO2 meant nothing, and declared the patient dead. Some time later, when the staff went in to prepare the patient's body for delivery to the morgue, they noticed the patient trying to breathe. The code was resumed, with the result that the patient finally expired several days later. Lawsuits are pending.

The evidence is overwhelming, capnography is a reliable predictor of ROSC in an arrest patient. Here are some studies to prove my point:
