Multicenter Study Comparative Study
Rescuer fatigue during actual in-hospital cardiopulmonary resuscitation with audiovisual feedback: a prospective multicenter study.
Rescuer fatigue during cardiopulmonary resuscitation (CPR) is a likely contributor to variable CPR quality during clinical resuscitation efforts, yet investigations into fatigue and CPR quality degradation have only been performed in simulated environments, with widely conflicting results. ⋯ During actual in-hospital CPR with audiovisual feedback, CC depth decay became evident after 90s of CPR, but CC rate did not change. These data provide clinical evidence for rescuer fatigue during actual resuscitations and support current guideline recommendations to rotate rescuers during CC delivery.

Comparative Study
Tuition of emergency medical dispatchers in the recognition of agonal respiration increases the use of telephone assisted CPR.
Bystanders cardiopulmonary resuscitation (CPR) increases survival in out-of-hospital cardiac arrest (OHCA). Emergency medical dispatchers (EMDs) can provide even totally inexperienced bystanders with instructions by telephone on how to resuscitate victims (T-CPR) until the emergency medical services (EMS) arrive. Agonal respiration makes it difficult for EMDs to identify cardiac arrests (CAs) which will prevent or delay initiation of T-CPR. The aim of this investigation was to study if tuition of EMDs can improve their ability to identify agonal respiration in OHCA to allow for more frequent offers of T-CPR. ⋯ Teaching EMDs to understand and recognize bystander descriptions of agonal respiration in patients with OHCA has resulted in a significant increase in offers of T-CPR in these situations.

Comparative Study
A national survey of prevalence of cardiopulmonary resuscitation training and knowledge of the emergency number in Ireland.
The aim of this survey was to establish prevalence of cardiopulmonary resuscitation (CPR) training within the last 5 years and reasons preventing training and initiation of CPR in Ireland as well as awareness of the emergency numbers. ⋯ Previous Irish and American population targets for CPR training have been surpassed in Ireland in 2008. New internationally agreed targets are now required. Meanwhile older people and those in lower socio-economic groups should be targeted for training. Awareness of at least one emergency number is very high in Ireland. Some geographical variation was found and this should be studied further.

Comparative Study
Comparison of efficacy of pulsed biphasic waveform and rectilinear biphasic waveform in a short ventricular fibrillation pig model.
The waveform designs and their relative defibrillation efficacy of external biphasic waveforms may differ remarkably among manufacturers. In this study, we compared pulsed biphasic waveform (PBW) with rectilinear biphasic waveform (RBW) and their effects on terminating ventricular fibrillation (VF). ⋯ In the setting of this experiment, there was no difference in terms of defibrillation efficacy and myocardial injury related to the electrical shocks of the two waveforms.

Comparative Study Clinical Trial
Is a 4 days transoesophageal training course sufficient to diagnose shock related pathologies?
Echocardiography is a useful tool in patients suffering from shock of unknown origin to evaluate cardiac function and volume status in order to decide on further treatment. The aim of the study was to evaluate how well participants could identify function, preload and regional wall motion abnormalities after attending a 4-day transoesophageal echocardiography (TOE) seminar. ⋯ The results of the investigation show that participants of a 4-day TOE seminar can interpret left ventricular function, preload and regional wall motion abnormalities correctly at a very high rate. TOE seminars seem to be effective in teaching basic theoretical knowledge of TOE.
