Improvement in the quality of cardiopulmonary resuscitation (CPR) may improve the survival rate following cardiac arrest. The aims of our study were to describe how recording of CPR maneuvers performed in our emergency department with real-time video and regular feedback learning may improve CPR. ⋯ We analyzed 45 cases, divided into three groups of 15 consecutive patients. Instantaneous rates of chest compression showed variation with 75% exceeding 110 cpm. There was a significant difference in instantaneous rates among groups (135 [112-150] in group 1, 123 [110-136] in group 2 and 124 [111-137] cpm in group 3, P<0.001). Ratio of hands-off time to total manual compression time (%) significantly decreased over time (Spearman correlation=-0.30, P=0.04). There were significant differences in hands-off time per minute among the groups (11 [3-28], 6 [2-21] and 7 [2-19] s min(-1), P<0.001). There was a significant improvement in time delay to first chest compression (11 [5-50], 20 [8-68] and 0 [0-12] s, P=0.01), but not in time delay to first ventilation (91 [31-190], 65 [17-121] and 24 [9-64] s, P=0.08). Data are median [25-75% interquartile]. Regular feedback learning from real-time video recording may improve the quality of major CPR variables.

Randomized Controlled Trial Comparative Study
A randomised trial comparing a 4-stage to 2-stage teaching technique for laryngeal mask insertion.
To compare the '4-stage' teaching technique (demonstration, deconstruction, formulation, performance) with the traditional '2-stage' teaching technique (deconstruction, performance) in laryngeal mask airway (LMA) insertion. ⋯ The 2-stage teaching technique is not statistically different to the 4-stage teaching method in efficacy of LMA insertion skill acquisition or retention.

Mild hypothermia is increasingly applied in the intensive care unit. Knowledge on the effects of hypothermia on respiratory parameters during mechanical ventilation is limited. In this retrospective study, we describe the effect of hypothermia on gas exchange in patients cooled for 24 h after a cardiac arrest. ⋯ Hypothermia possibly improves oxygenation and ventilation in mechanically ventilated patients. Results may accord with the hypothesis that reducing metabolism with applied hypothermia may be beneficial in patients with acute lung injury, in whom low minute ventilation results in severe hypercapnia.
