Randomized Controlled Trial
Accuracy of clinical assessment of infant heart rate in the delivery room.
Heart rate (HR) dictates intervention during neonatal resuscitation. Guidelines recommend that HR be assessed by auscultation or palpation. ⋯ Clinical assessment by 23 observers randomly allocated to assess HR by one of two methods in 26 infants, was found to be inaccurate and underestimate ECG HR. The mean difference between HR assessed by auscultation and palpation ECG and HR using methodology recommended by the Neonatal Resuscitation Programme was 14 and 22 beats per minute respectively.

Few prospective studies of the incidence and outcome of paediatric in-hospital cardiopulmonary arrest have been reported to enable quality assurance comparisons within and between institutions. ⋯ In-patient paediatric cardiac arrest has a mediocre outcome with a better outlook if the initial rhythm is hypotensive-bradycardia, VF or pulsatile VT. Doses of adrenaline greater than 15 mcg/kg given for non-shockable rhythms may cause secondary VF which has a worse outcome than primary VF.

Comparative Study
Clinical testing of cellular phone ringing interference with automated external defibrillators.
This study examined cellular phone ringing interference with automated external defibrillators (AED). ⋯ Clinical testing during ECG monitoring by an AED during call from a cellular phone did not show any analysis dysfunction during unshockable rhythms and provoked only transient dysfunction of the speaker device.

Randomized Controlled Trial Multicenter Study
Quality of lay person CPR performance with compression: ventilation ratios 15:2, 30:2 or continuous chest compressions without ventilations on manikins.
The new CPR guidelines emphasise chest compression depth and have increased the compression:ventilation ratio to cause less time intervals without chest compressions. How this change may influence the quality of chest compressions is not documented. Sixty-eight volunteers among travellers at Oslo international airport and a senior citizen centre performed 5 min of CPR on a manikin with compression:ventilation ratios 15:2, 30:2 or continuous chest compressions. ⋯ Number of compressions per minute was 40 +/- 9, 43 +/- 14 and 73 +/- 24 and percent no flow time 49 +/- 13%, 38 +/- 20% and 1 +/- 2%, respectively. In conclusion, continuous chest compressions without ventilations gave significantly more chest compressions per minute, but with decreased compression quality. No flow time for 30:2 was significantly less than for 15:2.
