Abstract During cardiopulmonary resuscitation (CPR), almost commercially dental chairs lack sufficient stability to perform effective manual chest compression (MCC). In our previous study, our technique that stabilizing stool can significantly reduce vertical displacement in a dental chair’s backrest. This study demonstrates that the efficacy of different methods for stabilizing 3 types of dental chair with a flat or a severely curved backrest exterior for effective MCC. Vertical displacement of the dental chair’s backrest was recorded. The data was captured with three different stool positions (no stool, under MCC, under shoulders). Reduction ratios were calculated to evaluate the effectiveness of the stool positions. In all types of dental chair, the technique significantly reduced the vertical displacements of the backrest. The reduction ratio varied nearly 40% under the area for MCC and 65% under the shoulder with a severely curved backrest exterior. With a flat shape of dental chair, these ratios were around 90% versus without a stool. The technique is a firm support and reduce the displacement of any type of dental chair’s backrest for effective MCC.

Abstract Background: Cardiopulmonary resuscitation (CPR) requires immediate start of manual chest compression (MCC) and defibrillation as soon as possible. During dental surgery, CPR could be started in the dental chair considering difficulty to move the patient from the dental chair to the floor. However, all types of dental chairs are not stable for MCC. We previously developed a procedure to stabilize a dental chair by using a stool. EUROPEAN RESUSCITATION COUNCIL (ERC) guideline 2015 adopted our procedure when cardiac arrest during dental surgery. The objective of this study was to verify the efficacy of a stool as a stabilizer in different types of dental chairs. Methods: Three health care providers participated in this study, and 8 kinds of dental chairs were examined. MCC were performed on a manikin that was laid on the backrest of a dental chair. A stool was placed under the backrest to stabilize the dental chair. The vertical displacement of the backrest by MCC was recorded by a camcorder and measured by millimeter. Next, the vertical displacement of the backrest by MCC were compared between with and without a stool. Results: In all 8 dental chairs, the method by using a stool significantly reduced the vertical displacements of the backrest by during MCC. The reduction ratio (mean [interquartile range]) varied between nearly 27 [20] and 87 [5] %. In the largest stabilization case, the displacement was 3.5 [0.5] mm with a stool versus 26 [5.5] mm without a stool (p < 0.001).

Abstract Objectives: Cardiopulmonary resuscitation (CPR) requires immediate start of external chest compression (ECC) and cardioversion as soon as possible. During dental surgery, CPR should be started in the dental chair considering difficulty to move the patient from the dental chair to the floor. However, all types of dental chairs are not stable for ECC. We previously developed a procedure to stabilize a dental chair by using a stool. ERC guideline 2015 adopted our procedure when cardiac arrest during dental surgery. The objective of this study was to verify the efficacy of a stool as a stabilizer in different types of dental chairs. Materials and methods: Three health care providers participated in this study, and 8 dental chairs were examined. ECC were performed on a manikin that was laid on the backrest of a dental chair. A stool was placed under the backrest to stabilize the dental chair. The vertical displacement of the backrest by ECC were compared between with and without a stool, and recorded by a camcorder. Results: In all 8 dental chairs, the method by using a stool significantly reduced the vertical displacements of the backrest by ECC. The reduction ratios were between nearly 39~85%, although it was different by chairs. Conclusions: Our procedure to stabilize dental chairs by using a stool significantly reduced the displacement of a backrest against ECC in all chairs. Clinical relevance: Effective ECC could be performed in dental chairs by using a stool when sudden cardiac arrest occurs during dental surgery.

A miniaturized chest compressor (MCC®) for cardiopulmonary resuscitation (CPR) was designed to serve as a compact portable device to overcome limitations of manual chest compression and of currently marketed mechanical devices. We sought to especially address constraints of size and weight of current devices, together with the need for ease of application and consistent compressions with appropriate force and depth. We further intended that the device allows for ease of evacuation and transport through small spaces. These objectives are responsive to the increasingly recognized requirements for uninterrupted chest compression including that which results from operator fatigue during manual compressions. Utilizing a garment applied to the torso, the device incorporated a telescopic piston for chest compression. The compressor was pneumatically powered so as to avoid the added weight and potential electrical adversity of power delivered by batteries. Pneumatic power was supplied by the same compressed air or oxygen tank, which is routinely carried by professional emergency medical rescuers. The MCC® was tested on a porcine model during cardiac arrest and resuscitation with comparisons to the current industry standard, the Michigan Thumper®. Arterial, carotid, and coronary perfusion pressures, together with end-tidal carbon dioxide as a surrogate for cardiac output, were measured. The MCC® threshold levels of pressure, flow, and end-tidal PCO2 are achieved, which were predictive of successful defibrillation with restoration of spontaneous circulation. We conclude that the MCC® is as effective as that of the established industry standard, the Michigan Thumper®, with the potential advantage of portability and facile application, especially for out-of-hospital resuscitation.
