摘　　要：目的通过监测舱内氧体积分数,评价Siaretron1000型呼吸机高压舱内使用的安全性。方法应用YHL型智能测氧仪监测呼吸机排气管路连接方式改进前后舱内氧体积分数变化。结果改进前,Siaretron1000型呼吸机在高压舱内使用期间随着治疗时间的延长,氧体积分数逐渐升高,甚至超过0.25;改进后,舱内氧体积分数较改进前明显下降。结论Siaretron1000型高压舱内专用呼吸机在多人舱(21.8m3)内使用时曾存在氧体积分数超标问题,经改进呼吸机排气管路连接方式,舱内氧体积分数可以达标。Objective To evaluate the safety of Siaretron 1000 ventilator in hyperbaric chamber by monitoring the oxygen volume fraction(φo2). Methods The φo2 was measured with YHL oxygen concentration detector before and after changing the connection mode of the ventilator exhaust pipe. Results Before the changing the connection of exhaust pipe, φo2 in the hyperbaric chamber increased as the treatment time prolonging,and even increased to more than 0.25. And it had decreased significantly after changing the pipe connection. Conclusion After improving the connection mode of ventilator exhaust pipe, the problem of surpassing the φo2 set standard in hyperbaric chamber would be solved and the φo2 may reach the standard.
