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

April 2, 2018 updated by: Jie Li, Rush University Medical Center
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.

Study Overview

Detailed Description

Chronic obstructive pulmonary disease or asthma patients who have positive response in bronchodilator test will be consented and enrolled, patients come back for the second bronchodilator assessment within one to three days after the initial bronchodilator test. Albuterol with different concentration will be provided to the patients via HFNC, patients will be assessed by spirometry after each concentration until bronchodilator response is positive and does not improve after the next dose.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Albuterol via High flow nasal cannula
Enrolled patients inhale bronchodilator (Albuterol Sulfate) with different concentration via High flow nasal cannula, prepared albuterol concentrations are 0.5mg, 1.0mg, 2.0mg and 4.0mg, patients will be assessed by spirometry after each concentration until bronchodilator response is positive and does not improve after the next dose.
High flow nasal cannula is a soft and flexible nasal prongs with adjustable head strap fits over the patient's ears, it delivers a broad variety of gas flows directly into the nares without gas jetting.
