Experimental
Active Comparator
new type of tracheotomy high-flow oxygen therapy (NTHF)
Respiratory Humidification Treatment( AIRVO TM 2)
Using NTHF, adjust the MR850 humidifier to invasive automatic gear, the temperature sensor automatically adjusts and maintains the gas temperature at the entrance of the tracheal tube at 37°C according to the feedback temperature, and monitors and maintains SpO2 between 94% and 100%. The monitored pulse oxygen saturation (SpO2) is used to adjust the concentration of the venturi valve and the corresponding oxygen flow rate. At the preset gas flow rate levels of 40L/min, 50L/min and 60L/min, the test pipeline is connected to optimize the breath. The actual gas flow rate value and the gas flow rate loss difference before and after the gas joint (screw joint), and at the corresponding gas flow rate, measure the gas temperature and humidity at the near-patient end of the pipeline.
Use AIRVOTM2 (Fisher & Paykel, Auckland, New Zealand), select the output gas temperature of 37°C, monitor and maintain SpO2 between 94% and 100%, and adjust the output gas flow rate of the therapy device to 40L/min, 50L/min and 60L/min, respectively. min, measure the actual gas flow rate value and the gas flow rate loss difference before and after each flow rate horizontal pipeline is connected to the conventional exhalation joint (matching special exhalation joint), and measure the gas temperature and humidity near the patient end of the pipeline at the corresponding gas flow rate.
