Respiratory rehabilitation therapy consists of a series of scientifically effective health promotion methods, emphasizing individualized programs. It includes cardiorespiratory training, aerobic and strength training, daily functional training, and psychotherapy. For COVID-19, respiratory rehabilitation may improve cardiorespiratory endurance and improve physical and mental health. Studies have shown that in the stable stage of the acute stage of the disease, the earlier the rehabilitation intervention, the better the recovery.

For post-discharge rehabilitation, a brief assessment of patient-related symptoms, cardiorespiratory endurance, physical fitness, and activities of daily living is required prior to discharge. For severe and critically ill patients, it is recommended to go to designated rehabilitation medical institutions to receive respiratory rehabilitation treatment. For mild and general patients, localities can designate medical observation in the community or at home, and gradually carry out some exercises to improve physical and mental health.

In terms of specific training methods, after patients with mild symptoms are discharged from the hospital, the rehabilitation mainly focuses on the recovery of physical fitness and psychological adjustment. According to the patients' past exercise habits and hobbies, they can gradually return to the activity ability before the onset of the disease. For critically ill patients, in physical training, especially when carrying out aerobic training programs, it is necessary to formulate exercise prescriptions in detail, and gradually increase the intensity and duration of exercise.

Generally speaking, aerobic exercise will require training 3 to 5 times a week for 20 to 30 minutes each time. Patients who are particularly prone to fatigue should take the form of segmented and intermittent exercise. For example, they can start from 3 to 5 minutes and do it in 3 segments every day, and strive to exercise for more than 10 minutes at a time in the second week. In terms of mastering the amount of activity, it should be noted that during the activity, the patient should be able to complete simple conversations without interruption, without obvious fatigue, especially the next day without fatigue, which is the most suitable situation.

For patients who are self-recovering at home, the most important thing is not to be completely bedridden, and to be active at home as much as possible - if they can walk, they can take steps; if they can stand, they should sit less; if they can sit, they should lie less; Also try to turn around more. In short, cannot stay in bed for a long time and stay in bed completely. Studies have shown that a day of complete bed rest reduces muscle strength by 2%.

For patients with high blood pressure and diabetes, first of all, it is emphasized that drug treatment and a reasonable diet should be ensured; in terms of exercise, attention should be paid to maintaining the amount of daily activities. You can change the habit and adopt the same amount. For example, change to a stationary treadmill, indoor jogging or brisk walking, practice Tai Chi or yoga, etc.
