现代呼吸监测仪多用电阻抗法监测呼吸波并报警指示呼吸停止。但遇到的一个最大问题是其不能辨别在部分呼吸系统抑制及完全或部分上呼吸道梗阻时仍伴而有无效性胸廓运动的情况,此时胸部无效运动及喘息经常被监测仪误解为正常呼吸波。故常不能及时报警。另外,监测仪可探测到心脏机械活动的跨胸阻抗,故在呼吸停止期间将其误认为呼吸运动。为解决上述问题,研制了AR-8800型呼吸监测仪。用五条杂种狗评阶本监测仪。观察几种
Modern respiratory monitor multi-impedance method to monitor respiratory wave and alarm instructions respiratory arrest. One of the biggest problems encountered is the inability to discern the presence of ineffective thoracic motion with partial respiratory depression and complete or partial upper airway obstruction where the chest is inefficiently motile and wheezing is often misinterpreted by the monitor as normal breathing wave. So often can not alarm. In addition, the monitor detects the transimpedance impedance of the heart’s mechanical activity and mistakenly identifies it as respiratory activity during the expiration of respiration. In order to solve the above problems, AR-8800 breathing monitor has been developed. Evaluate the monitor with five mongrel dogs. Observe several
