Short-term Forest Rehabilitation Influence on Pulmonary Ventilation in Patients with Chronic Obstructive Pulmonary Disease

In order to study the effect of short-term forest rehabilitation activities on the pulmonary ventilation function of people with chronic obstructive pulmonary disease (COPD), 20 COPD patients living in urban areas during the remission period were selected to carry out a 5-day forest rehabilitation activity in Kuanba Forest Health Center. By comparing the changes of various indicators of pulmonary ventilation function before and after the patients' rehabilitation activities, the impact of short-term forest rehabilitation on the pulmonary ventilation function of COPD patients and the related factors were analyzed and discussed. The results showed that short-term forest rehabilitation had a significant positive effect on the recovery of pulmonary ventilation function indexes in COPD patients, and the effect on female patients was higher than that of male patients; the correlation analysis showed that the lifting rate of FEF25%, FEF50%, FEF75%, FEF25%-75% of the instantaneous flow of forced expiratory was significantly (P<0.05) or extremely significantly (P<0.01) negatively correlated with age, the MVV lifting rate was significantly negatively correlated with the degree of lung function damage (P<0.05), and the one-second rate was significantly positively correlated with the degree of lung function damage (P<0.05), indicating that short-term forest health care played a greater role in COPD patients with younger age and lighter lung function damage.
