Return of Spontaneous Circulation

Capnography is usually a more reliable indicator of ROSC than carotid or femoral arterial pulse palpation.[3] A sudden increase in EtCO2 (>35–40 mm Hg) suggests ROSC. Other indicators of ROSC include the presence of a palpable pulse, blood pressure, and arterial line waveforms.[3] Palpation of a pulse during chest compressions may reflect venous pulsation. If rescuers are concerned that the capnograph is malfunctioning, blowing into the sidestream CO2 collecting tube is a quick way to evaluate this.
