无创呼吸机持续正道压力校准方法的探讨

无创呼吸机为患者提供呼吸支持与治疗,是一种临床广泛使用的医疗设备.随着使用年限的增加,可能会降低其准确度和可靠性,因此需进行定期校准.根据JJF 1997-2022《无创呼吸机》校准规范可知,大多数呼吸机的普适性较好,但迈瑞SV70s和科曼NV70因内部算法和触发灵敏度不一致,导致在校准持续正道压力时会默认为不工作或误触发.研究发现:采用在报警设置中关闭窒息时间、调节窒息吸气压力水平或将模拟肺连接至校准系统等方法,可成功完成校准工作.
Study on Calibration Method of Continuous Positive Airway Pressure for Non-invasive Ventilator
Noninvasive ventilator is a kind of medical equipment widely used in clinic to provide respiratory support and treatment for patients.As the age of use increases,its accuracy and reliability may decrease,so regular calibra-tion is required.According to the JJF 1997-2022"Non-invasive Ventilator"calibration specification,most venti-lators have good universality,but the Mindray SV70s and Komen NV70 default to not work or mistrigger when cali-brating continuous positive pressure due to inconsistent internal algorithms and trigger sensitivity.It was found that the calibration work could be successfully completed by turning off the choking time in the alarm setting,adjusting the suffocating inspiratory pressure level,or connecting the simulated lung to the calibration system.
