Overview
Brief 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.
Detailed Description
In this study, patients with acute exacerbations of copd who were included in both treatment and control groups, administered randomly oxyhydrogen generator with nebulizer (treatment group) or oxygen Nebulizer Machine (control group for the therapy. The therapeutic outcomes in both treatment and control groups are analyzed and evaluated to verify safety and effectiveness of the test product. This study is a multi-center, randomized, double-blind study. The trial lasted for about 10 days. The curative effect was observed for subjects in the First, the second, the third, the fourth, the fifth, the sixth, the seventh day, respectively as the observing time point. Total patients which are planned to be included are 108 cases, where, 54 cases in the treatment group and control group respectively are distributed in 10 clinical hospitals

Eligibility Criteria
Inclusion Criteria
- •meet the diagnostic criteria of chronic obstructive pulmonary disease (COPD)\[1\] : In the examination of pulmonary function, after inhalation of bronchodilator, the volume of forced air in one second accounted for 70% of forced vital capacity (FEV1 / FVC%) , fev180% ;
- •meet the diagnostic criteria of acute exacerbation of chronic obstructive pulmonary disease (AECOPD)\[2\] : compared with the stable phase, the patient's condition has continued to deteriorate, more than the normal changes in the daytime, that is, patients with chronic obstructive pulmonary disease foundation for acute onset, need to adjust the routine medication. There are at least 2 of the following 3 items in the continuous deterioration of clinical symptoms: 1 aggravation of shortness of breath; 2 increase of Sputum Volume; 3 purulent sputum; or at least 1 of the above 3 symptoms, but one of the other 5 indicators should be added, 1 fever; 2 increased respiratory frequency and heart rate by 20% compared with the baseline; 3 aggravated cough; 4 Pharyngodynia and runny in the last 5 days; 5 increased wheezing;
- •the age is over 40 years old and has the normal independent judgment ability patient, the male and the female are not limited;
- •AECOPD patients requiring in-patient Care;
- •patients with BCSS score ≥6 at the time of admission;
- •patients who volunteer for the trial and sign an informed consent form.
Exclusion Criteria
- •screening period of intravenous or oral administration of more than 80 mg / day of methylprednisolone or equivalent dose of other hormones or serious need for continuous non-invasive ventilation patients;
- •having a significant disease other than COPD, which, according to the researchers'judgement, would put the participants at risk for participating in the study or have an impact on the results of the study and the participants'ability to participate in the study;

- •Lung Rehabilitation: Participants in the Lung Rehabilitation Program during the study period;
- •a history of severe heart disease such as acute myocardial infarction, congestive heart failure (NYHA Class III and above) , Severe Arrhythmia and other acute heart disease;
- •serious primary diseases of important organs and systems, such as acute stroke, hypertension above moderate after treatment, active gastric ulcer, diabetes Mellitus (serious complication) , malignant tumor, etc.

Outcomes
Primary Outcomes
The Breathlessness, Cough, and Sputum Scale(BCSS score)
Time Frame: everyday from the baseline to the seventh day
The breathlessness, cough and sputum scale (BCSS) is a three-item questionnaire rating breathlessness, cough and sputum on a 5-point Likert scale from 0 (no symptoms) to 4 (severe symptoms).the total total is 12. Variables to be measured or calculated are: from the Baseline to the seventh day.
Secondary Outcomes
- COPD assessment test (CAT)(baseline and the seventh day)
- FEV1(baseline and the seventh day)
- Results Of Performance Evaluation Of Apparatus(everyday from the baseline to the seventh day)
- FVC(baseline and the seventh day)
- FEV1/FVC(baseline and the seventh day)
- PaO2(baseline and the seventh day)
- PaCO2(baseline and the seventh day)
- Potential of Hydrogen(baseline and the seventh day)
- oxygen saturation of blood(everyday from the baseline to the seventh day)
