Effect of HFNC device model on nasal airway pressure and comfort
devicesValue
When the flow rate reached ≥20 L/min, and the EIP and EEP of the two devices were significantly different (H-80 M > HFT-300, The pressure produced by different devicesValues are median (IQR), * represents Finally, the actual output flow rate was evaluated in the pipeline of the two devices. The flow rate measured by the H-80 M was significantly higher than that of the HFT-300 (The actual measured flow rate of devicesValue is the mean ± SD, * represents The actual output flow rate of different models of high-flow humidification therapy instruments. Values are median and standard deviation. The closer the data points are to the diagonal line, the closer the actual output flow is to the preset flow
