摘　　要：目的 实时动态观察在多人氧舱内常压和高压氧治疗（HBOT）时观察对象使用不同吸氧装具的吸氧效果.方法 对30例观察对象在常压和0.22 MPa下,采用不同吸氧装具吸氧时,左前臂背侧经皮氧分压（transcutaneous oxygen pressure,TcPO2））曲线变化进行连续全程监测.结果 （1）在常压及0.22 MPa下使用不用吸氧装具吸氧时,所有观察对象TcPO2曲线表现为上升阶段（吸氧开始后1～5 min上升到最高值）、峰值平台期（从到达最高峰值维持至开始减压）和下降阶段（从开始减压到停止吸氧后20 min）,曲线上升下降完全与吸氧同步.（2）吸氧装具使用情况易引起TcPO2曲线变化.（3）入舱前指导患者正确佩戴吸氧装具是保证TcPO2曲线正常的重要环节.结论 TcPO2曲线变化与吸氧同步,易受吸氧装具的使用情况影响;TcPO2曲线可作为实时动态监测多人氧舱内患者吸氧效果的客观指标.Objective To observe the oxygen-breathing efficacy by using different breathing apparatuses during normal pressure oxygen-breathing treatment and HBO treatment （HBOT） in the multi-seats chamber.Methods Changes in curve of transcutaneous oxygen partial pressure （TcPO2） for the 30 subjects,who had oxygen-breathing both at normal pressure and at a pressure of 0.22 MPa by using different types of apparatus were monitored continuously.Results （1） The curves of normal TcPO2 both at normal pressure and at 0.22 MPa were displayed in three stages：the compressing stage （1-5min after oxygen-breathing started until peak was reached） ; the plateau peak stage （the time when the peak arrived till decompression started） ; the decompression stage （the time when decompression was started till 20 minutes after oxygen-breathing was terminated）.The elevation and declining of the curve synchronized with oxygen-breathing.（2） Oxygenbreathing by using different types of breathing apparatus tended to induce changes in the TcPO2 curves.（3）Before entrance into the chamber,instruction on the correct wearing of oxygen-breathing apparatus was an important measure for maintenance of the TcPO2 curves.Conclusions The TcPO2 curves synchronized with oxygen-breathing and was obviously affected by different types of apparatus.The TcPO2 curve could be used as an objective indicator for dynamic and real-time monitoring of oxygen-breathing efficacy in the multi-seats chamber.
