Comparative Study
Oxygen requirement during cardiopulmonary resuscitation (CPR) to effect return of spontaneous circulation.
Recent scientific evidence has demonstrated the importance of good quality chest compressions without interruption to improve cardiac arrest resuscitation rates, and suggested that a de-emphasis on minute ventilation is needed. However, independent of ventilation, the role of oxygen and the optimal oxygen concentration during CPR is not known. Previous studies have shown that ventilation with high oxygen concentration after CPR is associated with worse neurologic outcome. We tested the hypothesis that initial ventilation during CPR without oxygen improves resuscitation success. ⋯ In a mild cardiac arrest model with generally good neurologic recovery, initial CPR ventilation with no O2 did not allow for ROSC. In contrast, CPR coupled with room air or higher oxygen levels result in a high rate of ROSC with good neurologic recovery. During CPR, the level of oxygenation must be considered, which if too low may preclude initial ROSC.

Comparative Study
The effect of the APLS-course on self-efficacy and its relationship to behavioural decisions in paediatric resuscitation.
Self-efficacy may predict performance following life-support training but may be negatively influenced by experiences during training. To investigate both this and the use of self-efficacy in self-assessment we investigated the relationship between self-efficacy and measured performance during a simulated resuscitation, and the effect of death of a simulated patient on self-efficacy. ⋯ Self-efficacy seems to be predictive of certain actions during a simulated resuscitation but does not correlate with quality of performance of resuscitation skills. Self-efficacy might therefore be useful as a predictor of the application of learning, but cannot be recommended for self-assessment. There is evidence to support the unwritten rule during simulation training the patient should not be allowed to die.
