Factors for survival after paediatric out-of-hospital cardiac arrest

CO2 (etCO2) valueswere obtained at 3, 9, 18 and 24min after beginning of resuscitation. These measurements and PaCO2 increase ( PaCO2) were compared between the three RR groups. Results: 30 rpm group had higher PaO2 (61mmHg) at 3min of resuscitation than 20 and 10 rpm groups (53 and 45mmHg p=0.05). However, no statistical differences between the three RR were found. PaCO2 values decreased up to 9min after CA in every group, but 20 and 30 rpm groups had lower PaCO2 values than 10 rpm group at 3min (58 and 55mmHg vs 75mmHg p=0.08). After that, PaCO2 values went up to 70mmHg (10 rpm group), 53mmHg (20 rpm group) and 39mmHg (30 rpm group) at 24min (p=0.06). There were no statistical differences in PaCO2 between the three groups during the whole resuscitation. Pigs resuscitated with 30 rpm had lower etCO2 at 3 and 9min than pigs with 10 rpm (p=0.01). There were no statistical differences in MAP. Conclusions: During pediatric resuscitation there were no significant differences in either oxygenation or ventilation between 10, 20 and 30 rpm. However, higher oxygenation and lower ventilation values were obtained with higher RR as well as lower etCO2 at 3 and 9min.
