研究目的:

1 评价对2种高流量湿化氧疗装置在气管切开脱机病人使用中的加湿性能,证明MTHF的加湿性能不劣于AIRVOTM2。 2 比较2种高流量湿化氧疗装置在使用中加湿性能的稳定性和临床效果,证明MTHF适用于气管切开脱机病人长期氧疗的可行性。  

Objectives of Study:

1 To evaluate the humidification performance of two kinds of high-flow humidified oxygen therapy devices within tracheotomied patients weaning from mechanical ventilation,and to prove that the humidification performance of MTHF is not inferior to that of AIRVOTM2. 2 Comparing the stability and clinical effect of two kinds of high-flow humidified oxygen therapy devices,and to prove that MTHF is suitable for long-term oxygen therapy for tracheotomized patients weaning from mechanical ventilation.

药物成份或治疗方案详述:

研究开始前,所有入选患者均签署知情同意书。使用计算机生成的随机数,符合入选标准的患者按照1:1的比例分为加温加湿高流量氧疗设备(试验组)和呼吸湿化治疗仪(AIRVOTM2, Fisher and Paykel Healthcare, Auckland, New Zealand)组(对照组)。试验组:使用自动调压氧气流量表、Fisher&PaykelMR850自动控温加热系统、文丘里空氧混合阀、氧气连接管、RT308加热呼吸管路、螺旋接头和密闭式吸痰管组成“加温加湿高流量氧疗设备”,密闭式吸痰管与气管切开导管连接。调节MR850为有创自动挡,温度传感器根据所回馈的温度自动调节并保持气管切开导管入口处气体温度在34~41℃,根据所监测的脉搏血氧饱和度(SpO2)来调节文丘里的浓度及所对应的氧气流量,维持SpO2在94%-98%,分别测试40L/min、50L/min和60L/min流量水平下导管远端(即患者近端)气体的温度和湿度。对照组:使用呼吸湿化治疗仪(AIRVOTM2, Fisher and Paykel Healthcare, Auckland, New Zealand)及专用加热管路和气管切开接头,选择输出气体温度37℃,根据所监测的脉搏血氧饱和度(SpO2)来调节吸氧浓度,维持SpO2在94%-98%,调整治疗仪输出气体流量分别为40L/min、50L/min和60L/min,测量每个流量水平下导管远端(即患者近端)气体的温度和湿度。 测量设备:使用电容式温湿度传感器(Rotronic,Bassersdorf, Switzerland),其反应时间<15s,温湿度测量范围分别为-50—100℃,相对湿度(Relative humidity ,RH)0—100%。 测量方法:每次改变流量水平后,我们允许至少30分钟的稳定时间。由于在相对湿度较高的环境下,传感器表面会形成冷凝,可能会损害仪器,故传感器将在稳定周期后放入系统进行测量。在传感器放入后先观察温度、相对湿度、绝对湿度10分钟,待确认数值稳定后,我们再记录后续5分钟的气体温度、相对湿度和绝对湿度。所有数据均使用数据采集软件传输并保存在计算机上。 测量时间:试验入组当天、第7天和第14天。 

Description for medicine or protocol of treatment in detail:

Before the start of the study, informed consent was signed by all selected patients. Using computer generated random numbers, patients who met the criteria were divided into two groups according to the ratio of 1:1.Observation group:MTHF is composed of automatic pressure regulating oxygen flow meter, Fisher & Paykel MR850 automatic temperature control heating system, Venturi air oxygen mixing valve, oxygen connecting tube, RT308 heating breathing tube, screw joint and closed suction tube.The MR850 was set in invasive mode (40°C/±3). The concentration of venturi and the corresponding oxygen flow are adjusted according to the pulse oxygen saturation (SpO2) monitored. Control group:Using AIRVOTM2( Fisher and Paykel Healthcare, Auckland, New Zealand)with tracheostomy interface, set the output gas temperature at 37℃, adjust the oxygen inhalation concentration according to the pulse oxygen saturation (SpO 2) monitored.For both group,SpO2 was matained between 94%-98% .For both systems, we tested temperature and humidity of gas at distal end of catheter (proximal end of patient) at each flow level of 20, 40, and 50 L/min. Measuring equitment:we use a capacitancetype moisture sensor(Rotronic, Bassersdorf, Switzerland ) ,the reaction time is less than 15s. The measuring range of temperature and humidity is - 50-100℃, and the relative humidity (RH) is 0 - 100%.
