Accepts Healthy Volunteers
Healthy volunteers are participants who do not have a disease or condition, or related conditions or symptoms
An interventional clinical study is where participants are assigned to receive one or more interventions (or no intervention) so that researchers can evaluate the effects of the interventions on biomedical or health-related outcomes.
An observational clinical study is where participants identified as belonging to study groups are assessed for biomedical or health outcomes.
Searching Both is inclusive of interventional and observational studies.
|Eligible Ages||40 Years - 80 Years|
- - Patients with acute exacerbation of chronic obstructive pulmonary disease(AECOPD) whose acute respiratory symptoms have been controlled after 5-7 day-standard AECOPD treatment including atomized or inhaled brochodilator plus oral or intravenous glucocorticoid (prednisone equivalent dose 40-50mg) or Pulmicort 2mg atomization Bid plus broad-spectrum antibiotics.
- - Patients with moderate and above chronic obstructive pulmonary disease diagnosed by spirometry, ie, forced expiratory volume in one second(FEV1)/forced vital capacity(FVC) <70% post-bronchodilator and FEV1% predicted value <80%.
- - Patients have signed an informed consent form.
- - Patients who is already using home nebulization therapy because of the severity of the illness.
- - Patients with bronchial asthma, pulmonary interstitial fibrosis, bronchiectasis, pulmonary embolism and other lung diseases; or hypertension, heart disease, chronic liver and kidney disease, diabetes, chronic gastrointestinal diseases, malignant tumors, critically ill patients.
- - Patient's mental state cannot match the observation or suffer from cognitive impairment.
- - Patient's peak inspiratory flow rates (PIFR) is less than 20L/min.
This trial id was obtained from ClinicalTrials.gov, a service of the U.S. National Institutes of Health, providing information on publicly and privately supported clinical studies of human participants with locations in all 50 States and in 196 countries.
Phase 1: Studies that emphasize safety and how the drug is metabolized and excreted in humans.
Phase 2: Studies that gather preliminary data on effectiveness (whether the drug works in people who have a certain disease or condition) and additional safety data.
Phase 3: Studies that gather more information about safety and effectiveness by studying different populations and different dosages and by using the drug in combination with other drugs.
Phase 4: Studies occurring after FDA has approved a drug for marketing, efficacy, or optimal use.
The sponsor is the organization or person who oversees the clinical study and is responsible for analyzing the study data.

Experimental: PIFR group
Active Comparator: control group
Drug: - PIRF measured by InCheck DIAL
Peak inspiratory flow rates(PIFR) will be measured using the InCheck DIAL(Clement Clarke International Ltd, Harlow, UK and Alliance Tech Medical). The InCheck DIAL is accurate to +/− 10% or 10 L/min, whichever is greater, and can measure flows in the range of 15 to 120 L/min. Dry powder inhaler(DPI) is to be prescribed if PIFRr is over 60L/min, otherwise pressure metered dose inhaler(pMDI) with spacer is given. All the patients will be given inhaled corticosteroid（ICS）/long-acting β agonist（LABA）. For symptomatic patients, long-acting anticholinergic agents(LAMA) will also be used.
Drug: - Regular treament
The choice of inhalers depends on physician's evaluation. The medication is the same as experimental group.
