Randomized Controlled Trial Comparative Study
Comparison of ventilation and cardiac compressions using the Impact Model 730 automatic transport ventilator compared to a conventional bag valve with a facemask in a model of adult cardiopulmonary arrest.
To determine the performance of two person CPR on an instrumented manikin by registered nurses using conventional bag valve mask (BVM) ventilation or the Impact Model 730 automatic transport ventilator (Impact 730, Impact Instrumentation, Inc., West Caldwell, NJ) in CPR mode using a face mask. ⋯ Compared to the BVM, the Impact 730 is as effective, easier to use and limits the amount of gas entering the stomach when used during adult CPR in a simulated setting.

Randomized Controlled Trial Multicenter Study
The effect of time on CPR and automated external defibrillator skills in the Public Access Defibrillation Trial.
The time to skill deterioration between primary training/retraining and further retraining in cardiopulmonary resuscitation (CPR) and automated external defibrillation (AED) for lay-persons is unclear. The Public Access Defibrillation (PAD) trial was a multi-center randomized controlled trial evaluating survival after CPR-only versus CPR+AED delivered by onsite non-medical volunteer responders in out-of-hospital cardiac arrest. ⋯ After primary training/retraining, the CPR skills of targeted lay responders deteriorate nominally but 80% remain competent up to 1 year. AED skills do not deteriorate significantly and 90% of volunteers remain competent up to 1 year.

Randomized Controlled Trial Comparative Study
Medical students teaching basic life support to school children as a required element of medical education: a randomised controlled study comparing three different approaches to fifth year medical training in emergency medicine.
Basic life support (BLS) by doctors has been shown to be of poor quality. To improve medical education training should be simplified, and simultaneously the learner should be involved more actively. To combine both ideas we trained medical students to give BLS courses and sent them to teach school children. This was a requirement for their emergency medicine course. Our model was compared to conventional teaching. ⋯ Medical students teaching BLS to school children as a compulsory element of their own medical training showed superior practical skills as compared to conventional teaching. Theoretical knowledge was equivalent to the control groups, although their course contained less theoretical information.

Practical impact of the European Resuscitation Council's BLS algorithm 2005.
The European Resuscitation Council (ERC) guidelines 2005 have brought major changes in the BLS algorithm. The aim of our investigation was to look for the practical impact of these modifications. ⋯ Compared to the 2000 BLS algorithm, the 2005 BLS sequence seems to be easier to learn and to retain, though nearly 60% of participants did not follow the new algorithm correctly. As expected, there was a significantly shorter time elapsing before the start of chest compressions when applying the 2005 algorithm. These findings should translate to better survival after cardiac arrest.

Randomized Controlled Trial
Artificial acrylic finger nails may alter pulse oximetry measurement.
Pulse oximetry is the most common technique to monitor oxygen saturation (SpO(2)) during intensive care therapy. However, intermittent co-oximetry is still the "gold standard" (SaO(2)). Besides acrylic nails, numerous other factors have been reported to interfere with pulse oximetry. Data of measurements with artificial finger nails are not sufficiently published. ⋯ Acrylic finger nails may impair the measurement of oxygen saturation depending on the pulse oximeter used and may cause significant inaccuracy. Hence, removal of artificial acrylic finger nails may be helpful to assure an accurate and precise measurement with pulse oximetry.
