Randomized Controlled Trial
Physical strain on advanced life support providers in different out of hospital environments.
To examine to what extent the type of emergency medical transportation influences the physical response of advanced life support providers. ⋯ External chest compression CPR is possible in a flying helicopter as it is in a moving ambulance vehicle. There is no clinical relevant difference in physical strain during ALS between a flying helicopter and a moving ambulance car. As would be expected, the exertion increases with duration of CPR.

Randomized Controlled Trial Comparative Study
The effectiveness of cardiopulmonary resuscitation instruction: animation versus dispatcher through a cellular phone.
We developed a cardiopulmonary resuscitation (CPR) instruction programme using motion capture animation integrated into cellular phones. We compared the effectiveness of animation-assisted CPR instruction with dispatcher-assisted instruction in participants with no previous CPR training. ⋯ Audiovisual animated CPR instruction through a cellular phone resulted in better scores in checklist assessment and time interval compliance in participants without CPR skill compared to those who received CPR instructions from a dispatcher; however, the accuracy of important psychomotor skill measures was unsatisfactory in both groups.

Randomized Controlled Trial
The impact of the ILCOR 2005 CPR guidelines on a physical fitness assessment: a comparison of old and new protocols.
St. John Ambulance Australia has used the performance of CPR for 10 min as a fitness test for its members. Recent changes in international guidelines for cardiopulmonary resuscitation caused concern that the new ILCOR protocol was more strenuous than the previous one. This study compared the two protocols to determine if there were significant differences and to allow an evidence-based decision on the continuation or modification of this practice. ⋯ The new protocol increases both objective and subjective measures of effort. While the absolute differences in workload are small, they are statistically significant. There are significant indicators of this difference in the first 3 min of assessment. Rescuers are more likely to be operating at a high-level of physical activity. To avoid increasing the demands of its mandatory fitness test, St. John should reduce the required performance time from its present 10 min.

Randomized Controlled Trial
Disposable laryngeal tube suction--a randomized comparison of two insertion techniques performed by novice users in anaesthetised patients.
Laryngeal tubes are supraglottic airway devices that can be used in alternative to a tracheal tube to provide ventilation during cardiopulmonary resuscitation. The product line has recently been expanded by the disposable laryngeal tube suction (LTS-D). We tested the hypothesis that, with a modified insertion technique (MIT), the rate of correct placement attempts within 45 s could be significantly increased compared to the standard insertion technique (SIT) recommended by the manufacturer. ⋯ Applying a MIT significantly reduced the time for successful insertion of an LTS-D by first-time users. Insertion within 45 s was significantly more frequent with this technique. Further studies need to be conducted to determine if the LTS-D can be recommended as a first-line airway during cardiopulmonary resuscitation.

Randomized Controlled Trial
Public access resuscitation program including defibrillator training for laypersons: a randomized trial to evaluate the impact of training course duration.
Time to cardiopulmonary resuscitation (CPR) is a main determinant of survival after out-of-hospital cardiac arrest. Only widespread implementation of training courses for laypersons can decrease response time. ⋯ A 2-h class is sufficient to acquire and retain CPR and AED skills for an extended time period provided that a brief re-evaluation is performed after 6 months.
