Abstract Background The aim of this study was to investigate the effect of feedback devices on visual attention and the quality of pediatric resuscitation. Methods This was a randomized cross-over simulation study at the Medical University of Vienna. Participants were students and neonatal providers performing four resuscitation scenarios with the support of feedback devices randomized. The primary outcome was the quality of resuscitation. Secondary outcomes were total dwell time (=total duration of visit time) on areas of interest and the workload of participants. Results Forty participants were analyzed. Overall, chest compression (P < 0.001) and ventilation quality were significantly better (P = 0.002) when using a feedback device. Dwell time on the feedback device was 40.1% in the ventilation feedback condition and 48.7% in the chest compression feedback condition. In both conditions, participants significantly reduced attention from the infant’s chest and mask (72.9 vs. 32.6% and 21.9 vs. 12.7%). Participants’ subjective workload increased by 3.5% (P = 0.018) and 8% (P < 0.001) when provided with feedback during a 3-min chest compression and ventilation scenario, respectively. Conclusions The quality of pediatric resuscitation significantly improved when using real-time feedback. However, attention shifted from the manikin and other equipment to the feedback device and subjective workload increased, respectively. Impact Cardiopulmonary resuscitation with feedback devices results in a higher quality of resuscitation and has the potential to lead to a better outcome for patients. Feedback devices consume attention from resuscitation providers. Feedback devices were associated with a shift of visual attention to the feedback devices and an increased workload of participants. Increased workload for providers and benefits for resuscitation quality need to be balanced for the best effect.

Cpr Quality

Although the use of audio feedback with devices such as metronomes during cardiopulmonary resuscitation (CPR) is a simple method for improving CPR quality, its effect on the quality of pediatric CPR has not been adequately evaluated. In this study, 64 healthcare providers performed CPR (with one- and two-handed chest compression (OHCC and THCC, respectively)) on a pediatric resuscitation manikin (Resusci Junior QCPR), with and without audio feedback using a metronome (110 beats/min). CPR was performed on the floor, with a compression-to-ventilation ratio of 30:2. For both OHCC and THCC, the rate of achievement of an adequate compression rate during CPR was significantly higher when performed with metronome feedback than that without metronome feedback (CPR with vs. without feedback: 100.0% (99.0, 100.0) vs. 94.0% (69.0, 99.0), p < 0.001, for OHCC, and 100.0% (98.5, 100.0) vs. 91.0% (34.5, 98.5), p < 0.001, for THCC). However, the rate of achievement of adequate compression depth during the CPR performed was significantly higher without metronome feedback than that with metronome feedback (CPR with vs. without feedback: 95.0% (23.5, 99.5) vs. 98.5% (77.5, 100.0), p = 0.004, for OHCC, and 99.0% (95.5, 100.0) vs. 100.0% (99.0, 100.0), p = 0.003, for THCC). Although metronome feedback during pediatric CPR could increase the rate of achievement of adequate compression rates, it could cause decreased compression depth.

Introduction The aim of this study was to determine the effect of hand positioning on the quality of external chest compression (ECC) by novice rescuers. Methods This observational simulation study was conducted for 117 included participants. After completion of an adult cardiopulmonary resuscitation (CPR) training program for 3-h, the participants selected which of their hands would be in contact with the mannequin during ECC and performed 5 cycles of single rescuer CPR on a recording mannequin. The participants were assigned to 2 groups: the dominant hand group (DH; n=40) and the non-dominant hand group (NH; n=29). The depth and rate of ECC were analysed to compare the effectiveness of ECC between 2 groups. Results The rate of ECC was significantly faster in the DH group (mean, 117.3 ±11.4/min) than in the NH group (mean, 110.9±12.2/min) (p=0.028). However, the depth of ECC in the dominant hand group (mean, 52.4±5.9 mm) was not significantly different from that in the non-dominant hand group (mean, 50.8±6.0 mm) (p=0.287). Similarly, the portion of ECC with inadequate depth in the dominant hand group (mean, 1.8±4.3%) was not significantly different from that in the non-dominant hand group (mean, 5.3±15.6%) (p=0.252). Conclusions ECC can be performed with an acceptably higher rate of compressions when the dominant hand of the novice rescuer is placed in contact with the sternum. However, the position of the dominant hand does not affect the depth of ECC. (Hong Kong j.emerg.med. 2014;21:382-386)

Impossible Task

The purpose of this prologue is to outline how I have approached the arrogant and impossible task of surveying an unborn century of law. I may also be able to illustrate that the nature and quality of the task is completely different from that attempted in the preceding papers. In the whole paper I have done little more than infer repeatedly, in different ways (a) that the shape of the future so far as law is concerned will be determined by the methods of communication adopted between sectors of the aerospace community and between the aerospace community and society at large, and (b) that the search for effective methods of communication is urgent. But my target is not the lawyers of our community—who I am not qualified to advise. I write for the other members of the Royal Aeronautical Society and I return to the task of persuading them that they have a role to play in evolving future laws for aerospace activities.

The Impact

Based on the molecular dynamics (MD) theory, in this article, we made a simulation study on titanium nanometric cutting process at different cutting depths, and analyzed the changes of the cutting depth to the effects on the work piece morphology, system potential energy, cutting force and work piece temperature in this titanium nanometric cutting process. The results show that with the increase of the cutting depth, system potential energy, cutting force and work piece temperature will increase correspondingly while the surface quality of machined work piece will decrease.
