摘要

Objectives: Active compression-decompression cardiopulmonary resuscitation is performed with a hand-held device equipped with a suction cup to actively lift the anterior chest during decompression. The perceptions of rescuers who perform active compression-decompression cardiopulmonary resuscitation, concerning the operation of the compression-decompression device are evaluated, in order to yield a better understanding of the relationship between the active compression-decompression device and the users.
Methods: A prospective, survey study design was used to evaluate the relationship between active compression-decompression and its users. The study participants were instructed to perform active compression-decompression cardiopulmonary resuscitation for 6 minutes; then they received the first part of questionnaire. After resting for 30 minutes, the rescuers performed standard cardiopulmonary resuscitation for 6 minutes and then answered the second part of the questionnaire.
Results: Of the 39 participants, 18 were male and 21 were female. Active compression-decompression cardiopulmonary resuscitation was more likely to cause significant discomfort or pain in some part of the body (92.3% versus 20.5%, p＜0.05); and operators were likely to experience discomfort during the decompression (66.7% versus 10.2%, p＜0.05). Standard cardiopulmonary resuscitation was reported by 3 8.5% of participants to cause no discomfort in either compression or decompression, in significant contrast to active compression-decompression cardiopulmonary resuscitation (2.6%). Of the participants, 61.5% (15/39) felt that the active compression-decompression grip was difficult or very difficult to handle. More than 50% of participants reported some discomfort in the wrist or palm while performing ACD-CPR.
Conclusion: The rescuer's wrist is placed in unusual positions during operation of the active compression-decompression device. The design of the device itself may contribute to its inconvenient operation, especially in decompression. Improving the design might improve performance.
