Study descriptionBrief Summary:The purpose for this study is to determine safety and effectiveness of the oxyhydrogen generator with nebulizer through a therapy for improving symptoms in patients with acute exacerbations of copd.
Condition or disease Intervention/treatment Phase Copd Exacerbation Acute Device: oxyhydrogenDevice: OxygenDrug: Conventional treatment Not Applicable
In this study, both treatment and control groups included patients with exacerbations of COPD who were randomized to receive either a nebulized electrolytic gas generator (treatment group) or an oxygen nebulizer (treatment control group). Treatment outcomes in the treatment and control groups will be analyzed and evaluated to verify the safety and efficacy of the test product. This study is a multicenter, randomized, double-blind study. The study lasted about 10 days. The curative probands were observed on the 1st, 2nd, 3rd, 4th, 5th, 6th, and 7th days. A total of 108 cases were admitted to the hospital, including 54 cases in the treatment group and 10 cases in the control group. ClinicArms and InterventionsGo to

Main outcome measures:
Daily Shortness of Breath, Cough and Sputum Scale (BCSS Score) from Baseline to Day Seven
The Shortness of Breath, Cough, and Sputum Scale (BCSS) is a three-item questionnaire that rates shortness of breath, cough, and sputum production on a 5-point Likert scale from 0 (no symptoms) to 4 (severe symptoms). The total is 12. Variables to be measured or calculated: from baseline to day 7.
Secondary outcome measures:
COPD Assessment Test (CAT) Baseline and Day Seven
The CAT includes eight items describing the presence or absence of cough, mucus production, chest tightness, shortness of breath, restricted activities at home, confidence to leave home, sleep, and energy. Symptoms are scored on a six-point scale from 0 to 5.
.The key outcome measure is an overall score, with 0 being the absence of any ill-health and 40 being the worst imaginable health. , the variable to be measured or calculated is: from baselineto day seven.
FEV1 Baseline and Day Seven
Change from Baseline in First Second Forced Expiration Amount (FEV1) after 7 days
FVC Baseline and Day Seven
Change from baseline in forced vital capacity (FVC) at 7 days
FEV1/FVC Baseline and Day 7
Change from baseline in forced expiratory volume in 1 second/forced vital capacity (FEV1/FVC) at 7 days
PaO2 baseline and day seven
Change from baseline in arterial partial pressure of oxygen (PaO2) after 7 days
PaCO2 Baseline and Day 7
Change from baseline in arterial carbon dioxide pressure (PaCO2) at 7 days
Hydrogen Baseline and Seventh Day Potential
Change in hydrogen potential (Ph) from baseline after 7 days
Daily oxygen saturation from baseline to day seven
Change in oxygen saturation after 7 days from baseline
Device performance assessment results daily from baseline to day seven
During each subject’s treatment period, the performance of the test apparatus must be evaluated according to the following 3 aspects every day after treatment, and the percentage of “good” is calculated.
Good: The product is more convenient for clinical use, easy to use, and error-free; General: The product is used normally in clinical practice, the operation requirements are general, and there are occasional small errors.
Poor: The product is difficult to use, and the harder it is to use, the more failures. The variables to be measured or calculated are: Results of device performance assessments at the end of each treatment day.
