Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
the face mask without EPAP
Will be collected clinical and anthropometric data of the participant. Will have the pulmonary function test every two months. Will be collected CT scan data. Patients will conduct 6MWT every two months. Borg scale data will be collected.The face mask without the application of EPAP will be used.
use the face mask without Expiratory Positive Airway Pressure(EPAP).
The subjects were divided into two groups. The first group use the face mask without EPAP, and the other group use the face mask with EPAP.
