Splet2 USES DURING CPR 7 CONFIRM ADEQUACY OF CHEST COMPRESSIONS: •Measurement of a low ETCO 2 value (< 10 mmHg) during CPR in an intubated patient suggests that the quality of chest compressions needs improvement. •Ensure proper rate (approximately 100/min) •Ensure proper depth with adequate release/recoil of thorax (1/2 thorax or … SpletPETCO2 was measured during CPR in 27 patients. After 1 minute, PETCO2 was higher in patients who had on-scene ROSC than in patients without ROSC (23.0 +/- 7.4 versus 13.2 +/- 14.7 mm Hg, P = .0002). After 2 minutes, PETCO2 was higher in patients with ROSC (26.8 +/- 10.8 versus 15.4 +/- 5.7 mm Hg, P = .0019).

Splet2 during CPR may differ from that during the normal cardiac output state. However, to our knowledge, no study has evaluated the effect of one-lung ventilation on ETCO 2 during CPR.
