The impact of the dental chair stabilization method on chest compressions

Abstract 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.
