  2. Introduction • We are analyzing the slow breathing in COPD (Chronic Obstructive Pulmonary Disease) patients with clinically significant dyspnea. • This survey given to 19 patients who have slow breathing problem within COPD patents • Clinical has approached with a survey answering five statements description before the breathing (MRC base line) exercise and after the breathing exercise (MRC week 8). • Scores were recoded.

  3. Survey • The survey is about if the patient agreeing with the statement, they have to respond circling “Yes” and if the patient is disagreeing respond “No”. • After this survey, patients are required to do the breathing exercise twice a day for 15 minutes. • After 8 weeks period time all the patients are required to do the survey again. • Check their breathing problem has cured or there is any improvements by doing the breathing exercise. • Record the scored of each patient.

  4. Methods • We did t-test to analyze how the breathing level has changed after the exercise. • T-test done using the JMP program. • Find the difference between MRC week 8 and MRC Baseline to do the t-test.

  5. Methods To do this t-test in JMP, choose Analyze  Distribution and select“difference” in Y column then click “ok” . From the above test we can see the statistics summary of the results.

  6. Conclusion • The p-value of this t-test result gives 0.4944. This tells us that there is no significant difference in the MRC differences. • After we have done the t-test for the COPD patients, the p-value tells that there is no differences between MRC week 8 and MRC baseline. Therefore there is no changes or improvement after the breathing exercise.
