“…Third, previous studies have shown that the height at which the rescuer performs chest compressions signi cantly impacts CPR e ciency and rescuer fatigue. 9,25 In the present study, the axillary line height of the manikin uniformly placed on the dental chair was approximately 55 cm, which did not correspond to the appropriate position of each participant and may have affected e ciency and fatigue. Finally, this study did not use objective indices such as electrocardiogram, electromyography, or oxygen saturation to measure participants' physical fatigue, but only a subjective RPE scale fatigue assessment to ascertain subjects' sense of fatigue.…”

“…Rescuer fatigue affects the quality of chest compressions. [7][8][9] After initiation of chest compressions, the depth of chest compressions decreases with time due to rescuer fatigue. As the depth of chest compressions decreases, coronary perfusion pressure decreases, resulting in a decreased likelihood of restoring spontaneous circulation.…”

“…7,8 It is also important to reduce fatigue from prolonged chest compressions. 9 In the e ciency of chest compressions, depth, speed, and recoil rate are especially important. Incomplete chest compressions reduce venous return to the heart and decrease mean arterial pressure and coronary and cerebral perfusion pressures.…”

Background To evaluate, how the influence of different with and without a support stool, impacts chest compressions on the dental chair. Methods Experiments were conducted on CPR training manikin on a dental chair. A stool was placed under the backrest of a dental chair to stabilize it. Chest compressions were performed for 5 minutes with or without a stool. Six values in chest compressions and the degree of fatigue were measured. Results According to the analysis of the quality of chest compressions without a stool or with a stool under the dental chair. The mean chest compression depth of With (57.29 ± 6.24mm) was significantly deeper than that of Without (53.86 ± 8.48 mm; p < 0.001). The mean chest compression rate and total chest compressions of With were significantly higher than that of Without. QCPR score of With (94.28 ± 10.57) was significantly higher than that of Without (72.0 ± 46.66; p < 0.001). The rating of perceived exertion of With (6.75 ± 1.20) was significantly lower than that of Without (8.75 ± 0.66; p < 0.001). Only the chest compression fraction and the chest compression rebound rate does not reach a significant difference. Conclusions The use of a support stool improved the quality of chest compressions on the dental chair and reduced rescuer fatigue. To perform effective CPR on a dental chair, it is important to stabilize the chair against chest compressions. Clinical relevance: Effective chest compressions could be performed in dental chairs by using a stool when cardiac arrest occurs during dental treatments.

“…A patient with cardiac arrest may require uninterrupted and effective CPR for a duration of at least 30-45 min [21]. It is a maneuver that demands a lot of physical stamina, while fatigue may affect the quality of chest compression [22,23]. For Student 2, there was a significant negative correlation between Angle 1 ′ and depth, which meant that more bent arms tended to have lower compression depth.…”

High-quality cardiopulmonary resuscitation (CPR) and training are important for successful revival during out-of-hospital cardiac arrest (OHCA). However, existing training faces challenges in quantifying each aspect. This study aimed to explore the possibility of using a three-dimensional motion capture system to accurately and effectively assess CPR operations, particularly about the non-quantified arm postures, and analyze the relationship among them to guide students to improve their performance. We used a motion capture system (Mars series, Nokov, China) to collect compression data about five cycles, recording dynamic data of each marker point in three-dimensional space following time and calculating depth and arm angles. Most unstably deviated to some extent from the standard, especially for the untrained students. Five data sets for each parameter per individual all revealed statistically significant differences (p < 0.05). The correlation between Angle 1′ and Angle 2′ for trained (rs = 0.203, p < 0.05) and untrained students (rs = −0.581, p < 0.01) showed a difference. Their performance still needed improvement. When conducting assessments, we should focus on not only the overall performance but also each compression. This study provides a new perspective for quantifying compression parameters, and future efforts should continue to incorporate new parameters and analyze the relationship among them.

“…However, V-CPR achieved better performance in terms of CCF, CCD, CCR, PCCR and RPE when they were compared with WV-CPR on the whole. Many previous studies have shown that high-quality chest compression is a key factor affecting the survival rate of patients with OHCA [2,[38][39][40]. Therefore, in order to improve the quality of CPR as much as possible, it is recommended that chest compression providers with no experience in CPR practice rescue OHCA patients following the CPR performance steps and rhythm prompts in the video.…”

Background: Chest compressions are the basis of cardiopulmonary resuscitation (CPR), and high-quality chest compressions can improve survival rate in patients with out-of-hospital cardiac arrest. Although many efforts have been made to improve the quality of CPR in inexperienced adults, the results are still not high, especially during emergencies. The primary purpose of this study is to investigate whether a brief instructional chest compression-only CPR video could improve chest compression quality in inexperienced adults. Methods: One hundred adults with no CPR experience (age: 20.28 ± 2.28 years; women: 50, men: 50) participated in this study. Participants completed body composition and handgrip strength measurements, and performed two CPR quality tests on the Laerdal ® Little Anne QCPR Manikin, namely without video-CPR (WV-CPR) and video-CPR (V-CPR). The WV-CPR quality test was performed first. After 2 minutes of continuous chest compression, the participants rested for 10 seconds and repeated 3 cycles (phase 1, phase 2, and phase 3). After resting for more than 72 hours, V-CPR quality test was conducted. During the V-CPR with video intervention, the participants also continued to compress the chest for 2 minutes, and then rested for 10 seconds, repeating 3 cycles. Results:In phase 1, compared with WV-CPR, the V-CPR has a significant increase (p < 0.001) in chest compression fraction (CCF) (56.31 ± 33.22% vs. 41.82 ± 32.30%) and percent of correct compression rate (PCCR) (96.17 ± 8.45% vs. 26.31 ± 37.55%). In addition, the V-CPR has significantly lower (p < 0.001) chest compression rate (CCR) (110.85 ± 2.40 cpm vs. 128.86 ± 24.52 cpm) and rating of perceived exertion (RPE) (11.89 ± 2.25 vs. 12.87 ± 2.25). For phases 2 through 3, V-CPR and WV-CPR achieved significant differences in CCF, CCD, CCR, PCCR, and RPE (p < 0.01). There were significant differences (p < 0.05) in CCF, CCD, chest compression rebound rate, and RPE among the different administration stages of both WV-CPR and V-CPR. Conclusions:The results of this study revealed that a brief instructional chest compression-only CPR video could improve chest compression quality for inexperienced adults by reducing fatigue and CCR, and increasing CCF and PCCR.
