目的：探讨高流量湿化氧疗系统对PICU呼吸系统疾病患儿面罩吸氧中的应用效果。方法将2012年8月-2013年12月入住儿童重症监护病房的面罩吸氧患儿60例，采用前瞻性随机对照法将患儿分为对照组和观察组各30例。观察组在普通气泡式氧气湿化装置的基础上，加用MR 850湿化器连接RT 308湿化氧疗管路对氧气进行温湿化氧疗；对照组采用普通气泡式氧气湿化装置进行氧疗,监测并比较氧疗24 h时两组患儿的痰液黏稠度，血PaO2、PaCO2、pH值，监护仪中的SpO2、呼吸次数。结果观察组的痰液黏稠度和对照组比较，Z=2.077，P＜0.05；观察组的PaO2和SpO2明显高于对照组，PaCO2和呼吸次数比对照组低（P＜0.05），但血pH值的差异无统计学意义（P＞0.05）。结论使用高流量湿化氧疗系统有利于气道分泌物的稀释，明显改善患儿低氧血症，提高氧疗效果。

Objective To explore the effect of high-flow humidification oxygen therapy system for children with respiratory system diseases. Methods With prospective randomized study, sixty patients in PICU were divided into control group and experiment group. Oxygen bubble humidifier was applied in control group while MR 850 humidifier together with oxygen bubble humidifier in experiment group. Sputum density, PaO2, PaCO2 and pH of the blood, SpO2 and respiratory rates were monitored and compared in both groups. Results The comparison of sputum density in both groups indicated statistical significance ( Z=2.077, P<0.05). There were higher PaO2 and SpO2 but lower PaCO2 and less respiratory rates in experiment group (P<0.05) and no difference was found in pH of the blood in two groups (P>0.05). Conclusion High-flow humidification oxygen therapy system benefits the dilution of airway secretions and the improvement of hyoxemia.
