The cardiopulmonary resuscitation skills of 105 trained hospital nurses were tested. Both basic and, for the first time in the UK, advanced skills were examined; basic skills were assessed by practical evaluation with a standard manikin and advanced knowledge by multiple choice questionnaire. No nurse adequately performed all four practical skills tested. Knowledge of the ventilatory aspects of resuscitation, defibrillation and advanced technique and drug management were also found to be poor. The findings add further support to adequate training of nurses in resuscitation skills. We describe a solution to overcome the heavy demands of such teaching and suggest that the same model be applied to the training of medical staff in resuscitation skills.
