“…reported that the ventilation rate of medical students was 10 breaths/minute higher than that of physicians in actual CPR situations [ 18 ]. However, the ventilation rate of providers without intervention was not markedly higher in our simulation-based study than in actual CPR situations [ 20 – 22 ]. It is assumed that the urgency of actual CPR situations can disrupt the attention of the provider responsible for ventilation.…”

Several auditory-based feedback devices have been developed to improve the quality of ventilation performance during cardiopulmonary resuscitation (CPR), but their effectiveness has not been proven in actual CPR situations. In the present study, we investigated the effectiveness of visual flashlight guidance in maintaining high-quality ventilation performance. We conducted a simulation-based, randomized, parallel trial including 121 senior medical students. All participants were randomized to perform ventilation during 2 minutes of CPR with or without flashlight guidance. For each participant, we measured mean ventilation rate as a primary outcome and ventilation volume, inspiration velocity, and ventilation interval as secondary outcomes using a computerized device system. Mean ventilation rate did not significantly differ between flashlight guidance and control groups (P = 0.159), but participants in the flashlight guidance group exhibited significantly less variation in ventilation rate than participants in the control group (P<0.001). Ventilation interval was also more regular among participants in the flashlight guidance group. Our results demonstrate that flashlight guidance is effective in maintaining a constant ventilation rate and interval. If confirmed by further studies in clinical practice, flashlight guidance could be expected to improve the quality of ventilation performed during CPR.

“…Although previous studies found differences in the median ventilation rates, the prevalence of hyperventilation in the CV groups was low; therefore, it is difficult to assess for efficacy in preventing hyperventilation. [12][13][14] This study revealed that CAV reduced hyperventilation and resulted in a respiratory rate more consistent with AHA recommendations compared to CV in this cohort, a group of experienced providers with recent BLS training. This difference was consistent over all four 1-minute segments of the study period.…”

“…2 This range was chosen as it was consistent with previous studies and still included the target rate of 10 breaths per minute recommended by the latest guidelines. 2,[12][13][14] Nevertheless, the significance of this effect is limited. If hyperventilation is redefined as >12 breaths per minute, hyperventilation still occurred 48% of the time in the CV group and zero percent in the CAV group.…”

“…In addition, the generalizability is limited given the low prevalence of hyperventilation in the conventional ventilation (CV) comparison groups, which is inconsistent with the literature. [12][13][14] Therefore, this study sought to examine ventilation rates between CV and CAV in a simulated OHCA model with local Basic Life Support (BLS)-trained providers performing metronome-guided chest compressions.…”

Introduction:Hyperventilation during cardiopulmonary resuscitation (CPR) negatively affects cardiopulmonary physiology. Compression-adjusted ventilations (CAVs) may allow providers to deliver ventilation rates more consistently than conventional ventilations (CVs). This study sought to compare ventilation rates between these two methods during simulated cardiac arrest.Null Hypothesis:That CAV will not result in different rates than CV in simulated CPR with metronome-guided compressions.Methods:Volunteer Basic Life Support (BLS)-trained providers delivered bag-valve-mask (BVM) ventilations during simulated CPR with metronome-guided compressions at 100 beats/minute. For the first 4-minute interval, volunteers delivered CV. Volunteers were then instructed on how to perform CAV by delivering one breath, counting 12 compressions, and then delivering a subsequent breath. They then performed CAV for the second 4-minute interval. Ventilation rates were manually recorded. Minute-by-minute ventilation rates were compared between the techniques.Results:A total of 23 volunteers were enrolled with a median age of 36 years old and with a median of 14 years of experience. Median ventilation rates were consistently higher in the CV group versus the CAV group across all 1-minute segments: 13 vs 9, 12 vs 8, 12 vs 8, and 12 vs 8 for minutes one through four, respectively (P <.01, all). Hyperventilation (>10 breaths per minute) occurred 64% of the time intervals with CV versus one percent with CAV (P <.01). The proportion of time which hyperventilation occurred was also consistently higher in the CV group versus the CAV group across all 1-minute segments: 78% vs 4%, 61% vs 0%, 57% vs 0%, and 61% vs 0% for minutes one through four, respectively (P <.01, all).Conclusions:In this simulated model of cardiac arrest, CAV had more accurate ventilation rates and fewer episodes of hyperventilation compared with CV.Nikolla DA, Kramer BJ, Carlson JN.

“…For example, prehospital care professionals have the advantage of being able to prepare themselves in advance, as they are briefed during transportation in the ambulance (Larsson & Engst€ om 2013). Many studies of CPR address biophysical/medical-and technicalaspects of the procedure (Chen et al 2014, Cho et al 2014, Hasegawa et al 2014. Although knowledge of these aspects is critical for decreasing mortality rates, there is an urgent need to further study health care professionals' subjective experiences of, and feelings associated with, conducting CPR to elucidate their needs.…”
