We examined the relationship between time from collapse to arrival of emergency medical services (EMS) and survival to hospital discharge for out-of-hospital ventricular fibrillation cardiac arrests in order to determine meaningful interpretations of this association. ⋯ The results of our analyses show that survival from out-of-hospital cardiac arrest does not decline at a constant rate following collapse. Models that incorporate changes that reflect the physiological alterations that occur following cardiac arrests are a more accurate way to describe changes in survival rates over time than models that include only a continuous term for time.

We have previously demonstrated that early intra-nasal cooling improved post-resuscitation neurological outcomes. The present study utilizing a porcine model of prolonged cardiac arrest investigated the effects of intra-nasal cooling initiated at the start of cardiopulmonary resuscitation (CPR) on resuscitation success. Our hypothesis was that rapid nasal cooling initiated during "low-flow" improves return of spontaneous resuscitation (ROSC). ⋯ Intra-nasal cooling initiated at the start of CPR significantly improves the success of resuscitation in a porcine model of prolonged cardiac arrest. This may have occurred by preventing brain hyperthermia.

Randomized Controlled Trial Comparative Study
Rescuer fatigue and cardiopulmonary resuscitation positions: A randomized controlled crossover trial.
During cardiopulmonary resuscitation (CPR), it is recommended to alternate rescuers every 2 min when two or more rescuers are available, regardless of the rescuer's position. It is unclear, however, whether rescuer fatigue depends on the rescuer's position. ⋯ CPR is best performed in a kneeling position. In order to minimize rescuer fatigue, we recommend alternating rescuers every 2 min while kneeling or standing on a taboret, and every 1 min while standing on the floor.

Randomized Controlled Trial Comparative Study
The effects of different instructional methods on students' acquisition and retention of cardiopulmonary resuscitation skills.
The need was evident for the evaluation of applicability and effectiveness of different types of instructional strategies to teach CPR skills. Therefore, the aim of this study was to evaluate the effects of traditional, case-based, and web-based instructional methods on acquisition and retention of CPR skills. ⋯ The students in traditional and case-based instruction groups showed better CPR performance than students in web-based instruction group that used video self-instruction as a learning tool.
