Randomized Controlled Trial Comparative Study
Effect of a reminder video using a mobile phone on the retention of CPR and AED skills in lay responders.
Skills related to cardiopulmonary resuscitation (CPR) and automated external defibrillator (AED) use by lay responders decay rapidly after training, and efforts are required to maintain competence among trainees. We examined whether repeated viewing of a reminder video on a mobile phone would be an effective means of maintaining CPR and AED skills in lay responders. ⋯ Repeated viewing of a reminder video clip on a mobile phone increases retention of CPR and AED skills in lay responders.

Randomized Controlled Trial Multicenter Study
The impact of increased chest compression fraction on return of spontaneous circulation for out-of-hospital cardiac arrest patients not in ventricular fibrillation.
Greater chest compression fraction (CCF, or proportion of CPR time spent providing compressions) is associated with better survival for out-of-hospital cardiac arrest (OOHCA) patients in ventricular fibrillation (VF). We evaluated the effect of CCF on return of spontaneous circulation (ROSC) in OOHCA patients with non-VF ECG rhythms in the Resuscitation Outcomes Consortium Epistry. ⋯ This is the first study to demonstrate that increased CCF among non-VF OOHCA patients is associated with a trend toward increased likelihood of ROSC.

Randomized Controlled Trial Comparative Study
Comparison of six different intubation aids for use while wearing CBRN-PPE: a manikin study.
Respiratory failure following chemical exposure can be fatal and although supraglottic airway devices have been evaluated for use in the management of CBRN casualties' intubation remains the gold standard airway. ⋯ In this manikin-based study all intubation aids evaluated while wearing CBRN-PPE were adversely affected by the loss of dexterity associated with wearing Butyl gloves. Standard intubation and intubation utilising a stylet resulted in the fastest intubation times; whereas the ILMA offers the highest intubation success rate and was deemed to be the easiest intubating aid to use. An important consideration with regards future research is the impact of a learning curve with regards to different intubation aids and whether preassembling all the intubation aids prior to the intubation attempt may improve intubation speed. The impact of intubator familiarity with regards to individual intubation aids is also an important consideration but established intubation aids like the Bougie are more difficult to use when dexterity is reduced due to CBRN-PPE.

Comparative Study
Automated external defibrillators and in-hospital cardiac arrest: patient survival and device performance at an Australian teaching hospital.
To evaluate the effect of automated external defibrillators (AEDs) on patient survival and to describe the performance of AEDs after in-hospital cardiac arrest. ⋯ Availability of AEDs was not independently associated with hospital survival. Shockable presenting rhythms were not common and, in keeping with the manufacturer's specifications, the AEDs did not shock all potentially shockable rhythms. The hands-off time associated with automated rhythm management was considerable.

Sodium nitroprusside-enhanced CPR, or SNPeCPR, consists of active compression-decompression CPR with an impedance threshold device, abdominal compression, and intravenous sodium nitroprusside (SNP). We hypothesize that SNPeCPR will improve post resuscitation left ventricular function and neurological function compared to standard (S) CPR after 15 min of untreated ventricular fibrillation in a porcine model of cardiac arrest. ⋯ In this pig model, after 15 min of untreated ventricular fibrillation, SNPeCPR significantly improved 24-hour survival rates, neurologic function and prevented post-resuscitation left ventricular dysfunction compared to S-CPR.
