Table 2 Baseline characteristics in rats resuscitated from cardiac arrest.

	DHC only	DHC + atropine
Bodyweight (g)	504 ± 8	504 ± 8
PaO₂ (mmHg)	85 ± 4	81 ± 1
PaCO₂ (mmHg)	39 ± 4	40 ± 4
pH	7.44 ± 0.02	7.45 ± 0.02
Blood temperature (°C)	37.0 ± 0.1	37.0 ± 0.1
Heart rate (beats/min)	333 ± 18	348 ± 8
Mean arterial blood pressure (mmHg)	145 ± 8	140 ± 4
ROSC attempts (n)	2.5 ± 1.2	2.0 ± 0.8
Shocks (n)	7 ± 4	7 ± 4
Total time to ROSC (min)	13.8 ± 1.0	13.3 ± 0.7

The table summarizes the baseline characteristics in rats prior to cardiac arrest and resuscitation. Also the number of shocks and ROSC attempts and total time to ROSC are given prior to the treatment with DHC and with or without atropine. Statistics: We observed differences between the two study groups on any of the measured parameters by comparison with a student's t-test (p = ns). Values are expressed as average ± SE, with n = 4 per group, see Methods for further details.
