Introduction:
Somdej Phra Phutthlertla Hospital reported from 1 October 2017 to 31 August 2018 had 675 OPD-COPD patients and 2585 treatment, 204 IPD-COPD patients and 436 treatment, 39 COPD death=7.59% Prevent and promote COPD patients to stop smoking is necessary and good fitness.

Objectives:
Prevent and promote physical program to COPD patients. Test 6 minute walk test and lung function test to COPD patients. Comparative 6 minute walk test and lung function test between smoking and stop smoking in COPD patients. Send smoking COPD patients to stop smoking clinic.

Methods:
This was a group selective trial. The sixty COPD patients in Samut Songkhram Hospital clinic were recruited and randomly assigned in two groups; Experimental group: 30 smoking COPD patients - 5 female aged 67.4±7.57, 25 male aged 62.58±10.30. BMI=22.98±10.87; and control group: 30 stop smoking in COPD patients - 5 female aged 67.6±12.34, 27 male aged 63.77±11.06, BMI=21.428±4.1. Both groups were tested with 6 minute walk test and lung function test then compared the two groups and instructed physical program to the COPD patients.

Results:
Experiment groups were divided female and male. The 6 minute walk test in smoking COPD patients was 305.23 ± 58.36 m. lung function tes: FEV1= 1.44 ± 0.56, FVC 2.19±0.89, FEV1/ FVC=66.3±12.73%. Control group- stop smoking: 6 minute walk test=368.87 ± 53.49 m, lung function test-FEV1=1.57 ± 0.77 , FVC 2.25±0.77 FEV1/ FVC=69.0±13.18 % Significant of condition (p=0.00) in 6 minute walk test.

Conclusion(s):
The 6 minute walk test of stop smoking COPD patients > smoking COPD patients is significantly. Lung function test between stop smoking COPD patients > smoking COPD patients is not statistically significant. And the smoking COPD can stop smoking 10/30, (33.33%).
