Comparative Study
Role of resuscitative emergency field thoracotomy in the Japanese helicopter emergency medical service system.
We investigated whether emergency thoracotomy (ET) performed in pre-hospital settings contributed to saving the lives of blunt trauma patients with impending or recent cardiac arrest. ⋯ These findings indicate that "early access" to a doctor's expertise and the performance of an "emergency field thoracotomy" might be two important factors for improving the possibility of saving the lives of blunt trauma patients with impending or recent cardiac arrest.

Randomized Controlled Trial Comparative Study
Effects of AED device features on performance by untrained laypersons.
Our study evaluates the impact of features of automated external defibrillators (AEDs) on the performance and speed of untrained laypersons to deliver a shock and initiate CPR after a shock. ⋯ Most untrained laypersons were successful in delivering a shock. Device features had the most impact on these functions: ability and time to power-on device, adequacy of pad position and initiation of CPR.

Comparative Study
An algorithm to discriminate supraventricular from ventricular tachycardia in automated external defibrillators valid for adult and paediatric patients.
To adapt adult automated external defibrillator (AED) arrhythmia analysis algorithms for paediatric use through the addition of an algorithm to accurately discriminate supraventricular tachycardia (SVT) from ventricular tachycardia (VT) that is valid for both adult and paediatric patients. ⋯ A new algorithm to discriminate SVT/VT was designed that showed high SVT specificity and VT sensitivity in both adults and children. This algorithm could be incorporated into current AEDs with arrhythmia analysis algorithms designed for adult patients to accurately diagnose fast-rate paediatric SVT.

Randomized Controlled Trial Comparative Study
Out-of hospital advanced life support with or without a physician: effects on quality of CPR and outcome.
The presence of physicians is believed to facilitate optimal management of out-of-hospital cardiac arrest, but has not been sufficiently documented. ⋯ Survival after out-of-hospital cardiac arrest was not different for patients treated by the PMA and non-PMA in our EMS system.

Multicenter Study Comparative Study
Cardiac arrest in Irish general practice: an observational study from 426 general practices.
Sudden Cardiac Death accounts for approximately 5000 deaths in Ireland each year. Nationally, out-of-hospital cardiac arrest has a very low resuscitation rate, reported at less than 5%. Ireland has a well developed general practice network which routinely manages emergencies arising in the community setting. However, little is known about its potential impact on Sudden Cardiac Death. This study reports on the incidence and management of cardiac arrest in Irish general practice. ⋯ Cardiac arrest in general practice is compatible with structured, effective interventions and significant rates of successful resuscitation. All general practices should be capable of providing this care.
