The Effects of Different Flow Settings on Lung Impedance Using Two New HFNC Devices: A Randomized Crossover Study on Healthy Volunteers

Detailed Summary

This prospective, randomized crossover trial will enroll adult healthy volunteers. Initially, the subject's peak inspiratory flow will be measured using a mask connected with a respiratory monitor. Subsequently, the volunteers will undergo HFNC treatment at different flow settings while their peak inspiratory flow will be continuously monitored. The primary outcome of this study is the lung aeration with different flow settings. Secondary outcomes include the lung aeration with different devices, subject's comfort at different flow settings, and the correlation between the subject's peak inspiratory flow measured by HFNC and by a mask connected with a respiratory monitor.
