Heart failure is the leading cause of death in dialysis patients. Cardiac arrest due to hypotension may also occur during dialysis therapy. If cardiac arrest is elicited, manual chest compressions (MCCs) should be started as soon as possible. However, all types of dialysis chairs are not stable for MCC, because there is no steady support between the backboard of the dialysis chair and the floor. These conditions may alter the effectiveness of MCC.
We investigated whether a round chair is effective in supporting the dialysis chair for MCC. Four adult males performed MCC on a mannequin placed on three dialysis chairs. MCC was performed in sets of 2 (each set was 100 times per minute) per person, with and without a round chair. A total of 4,800 compressions were performed by four executors.
When the chair was not used as a stabilizer, the mean values of the fluctuation range were 20.8 ± 8.1 mm, 18.7 ± 5.5 mm, and 12.8 ± 1.8 mm, respectively. When the chair was used, the mean values of the fluctuation range were 6.1 ± 1.1 mm, 7.5 ± 2.1 mm, and 1.0 ± 0 mm, decreasing by 70%, 59%, and 92%.
MCC performed with the stool under the backrest as a stabilizer was effective in supporting the dialysis chair.
心力衰竭是透析患者的主要死因。透析治疗期间也可能因低血压导致心脏骤停。一旦发生心脏骤停，应尽快开始进行胸外按压（MCC）。然而，并非所有类型的透析椅都能稳定地进行胸外按压，因为透析椅的背板与地面之间缺乏稳定支撑。这些情况可能会改变胸外按压的效果。
我们研究了圆椅在支撑透析椅进行胸外按压方面是否有效。四名成年男性在放置于三把透析椅上的人体模型上进行胸外按压。每人在有和没有圆椅的情况下，以每组2次（每组每分钟100次）的频率进行胸外按压。四名执行者共进行了4800次按压。
当不使用椅子作为稳定器时，波动范围的平均值分别为20.8±8.1毫米、18.7±5.5毫米和12.8±1.8毫米。当使用椅子时，波动范围的平均值分别为6.1±1.1毫米、7.5±2.1毫米和1.0±0毫米，分别下降了70%、59%和92%。
将靠背下方的凳子作为稳定器进行胸外按压，对支撑透析椅是有效的。
