Evaluation on the Efficacy of Bronchodilator Nebulization Via High Flow Nasal Cannula

• Status: Completed
• Trial end date: 2018-03-31
• Target enrollment: 0
• Participant gender: All

Summary

High-humidity nasal cannula (HFNC) has been shown to be effective in improving oxygenation and avoiding intubation in multiple randomized control trials, it is also suitable and feasible for long term use. Aerosol delivery via HFNC will minimize interruptions and improve patient compliance, bench study and radionuclide imaging study done in healthy volunteers demonstrated that aerosol can be effectively delivered using HFNC. This study aims to evaluate the efficacy of bronchodilator delivered via HFNC in chronic pulmonary obstructive disease or asthma patients.
