Interventions
To compare the asymmetrical HFNC with the conventional HFNC, the devices will be fitted to the patient in turn(asymmetric ->
conventional), and the effect of each will be verified by changing the flow rate provided. The order of fitting the asymmetrical device and the conventional device will be randomised.

| Measure | Time frame |
|---|---|
| The difference in ventilation volume between devices will be used as the evaluation item. The patient wears electrodes for electrical impedance tomography (EIT) so that the ventilation volume under spontaneous breathing can be estimated from the measured electrical resistance. The patient wears each device and sets the flow rate provided by each device. After breathing naturally for 15 minutes, the ventilation volume is estimated using the electrical resistance recorded by EIT. The estimated ventilation volume is compared between each device | — |
