Abstract：Objective To explore the essentiality and feasibility of metered dose inhaler for patients with chronic obstructive pulmonary disease(COPD). Methods Totally 120 COPD patients were applied metered dose inhaler.Preliminary application according to the 7-step procedure was recorded and records of application were repeated when patients got out of hospital and two weeks after discharge. Results Eighteen patient in 120(15%)had correctly used metered dose inhaler in preliminary application.The mistakes in the application were inhalation after press(90 times),repeated-consperge before inhalation(30 times),no breath-holding after inhalation(28 times),no mouth-rinse after inhalation(20 times),no shaking before application(18 times)and glucocorticosteroid inhalation ahead β2 receptor agonist(80 times).When discharged,patients with correct usage increased to 88(73%). Conclusions Therapeutic effect is depressed by incorrect use of metered dose inhaler in COPD patients,which can be improved by regular and standardized guidance.
