Physiological parameters at baseline.

<p>Note: Amp and AUC were calculated as the average of the data collected 30s before the detect time.</p><p>No statically significant differences were detected in any parameters between the two groups.</p><p>LQ group: low quality resuscitation group; HQ group: high quality resuscitation group; HR: heart rate; CPP: coronary perfusion pressure; P_ETCO₂: pressure of end-tidal carbon dioxide; AUC: area of under the curve; Amp: amplitude of POP; PVA: Pulse Oximeter Voltage Amplitude; PVPG: Pulse Oximeter Voltage Plehtysmography.</p><p>Physiological parameters at baseline.
