Description
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;

- 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.
- confirmed and suspected cases of lung cancer;
- a history of one or more lobectomies;
- limited understanding and poor compliance;
- lack of or restricted legal capacity;
- those who have participated in clinical trials of other drugs or medical devices within 30 days prior to screening but have not reached the end point of the trial;
- pregnant, lactating women and women of childbearing age who do not agree to effective contraceptive measures during the study period;
- Persons with mental or physical disabilities;
- a suspected or confirmed history of alcohol or Drug Abuse;
- those who are known to be intolerant to inhalation therapy;
- AST, ALT were 3 times higher than the normal upper limit, creatinine ≥176.8 MMOL / l;
- shock or other Hemodynamics instability;
- people with active Hepatitis A, hepatitis B, HIV, tuberculosis, and Infectious Disease Connective Tissue Disease;
- intravenous hormone therapy for more than 5 days after an acute episode;
- non expectorant antioxidants, including high doses of vitamin C and Vitamin E;
- the researcher did not consider it appropriate to participate in this study.

What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
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 Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
COPD assessment test (CAT)
Time Frame: baseline and the seventh day
|
CAT includes eight items describing the presence or absence of cough, mucus production, chest tightness,ff ort dyspnoea, limitation of activities at home, sense of confidence about leaving the home, sleep and the feeling of having lots of energy.
Th e symptoms are assessed on a six-point scale from 0 to 5. Th e main outcome measure is the total score, where 0 indicates the absence of any negative infl uence of disease and 40 the worst imagin-able health status , Variables to be measured or calculated are: from the Baseline to the seventh day.

Results Of Performance Evaluation Of Apparatus
Time Frame: everyday from the baseline to the seventh day
|
During the treatment period of each subject, the performance of the test instrument must be evaluated from the following 3 aspects every day after treatment, and the percentage of "good" should be calculated. Good: The clinical use of the product is more convenient, easy to operate, no fault; General: Normal clinical use of the product, General Operation Requirements, there are occasional small failures. Poor: The product is difficult to use, more difficult operation, there are more failures. Variables to be measured or calculated are:Results of instrument performance evaluation at the end of each treatment day. |
