目的:在不同周围环境,相同的加湿器设置条件下,观察湿化器(输出端)与气管插管入口处(吸入端)温度湿度差异,以及时调整湿化器设置,达到更好的湿化效果。方法:入选病例均采用呼吸机自带湿化器进行湿化,将湿化仪输出端温度设置为37?C,并监测湿化仪输出端温湿度。同时每日对环境温度及湿度进行记录,观察气管插管入口输入端实际温湿度,并设置报警限制(温度下限≤0?C,上限≥40?C;湿度下限≤30mg/L),遇报警时及时调整。结果:实验组与对照组患者在温湿度监测仪的监测效果方面存在着明显的统计学差异(P<0.05),自制湿温度监测仪能够更为显著地监测人工气道湿化的效果。结论:自制温湿度监测仪比一般的监测器在人工气道湿化效果中要佳,值得临床推广借鉴。
OBJECTIVE: To observe the difference in temperature and humidity between the humidifier (output end) and the endotracheal tube inlet (inhalation end) under the different ambient conditions and the same humidifier setting conditions, and to adjust the humidifier settings in time to achieve a better wetness Effect. Methods: Selected cases were ventilated with a humidifier humidifier, humidifier output temperature was set to 37? C, and monitor the humidifier output temperature and humidity. At the same time, daily record the ambient temperature and humidity, observe the actual temperature and humidity at the inlet of endotracheal intubation, and set the alarm limit (temperature lower limit≤0? C, upper limit≥40? C; humidity lower limit≤30mg / L) Timely adjustment. Results: There was a significant difference between the experimental group and the control group in the monitoring effect of the temperature and humidity monitor (P <0.05). The self-made wet temperature monitor could more obviously monitor the artificial airway humidification effect. Conclusion: Home-made temperature and humidity monitor better than the average monitor in artificial airway humidification effect, it is worth clinical promotion.
