Study on Post-Acute COVID-19 Syndrome in Improvement of COVID-19 Rehabilitated Patients by Respiratory Training

Relevant studies have shown that breathing training can improve the exercise capacity, lung function, and respiratory rate of patients who have recovered from COVID-19. Difficult and other aspects are safe and effective. However, because COVID-19 is an emerging disease, the clinical research literature so far has limited Clinical data are still insufficient, and the effect of respiratory training on the breathing and physical function of COVID-19 patients has not been determined, and most of the patients are not living in the hospital. How to carry out simple and effective breathing training to reduce the long-term impact of COVID-19 on patients is worthy of continuous discussion. This study will assist COVID-19 patients to perform respiratory training with incentive spirometer intervention, and collect patients before and after the intervention Oxygen requirements, blood draw values and Post-COVID-19 Functional Status scale(PCFS scale) and other data to explore and evaluate the effect of interventional breathing training on the improvement of symptoms of new coronary pneumonia, as a reference for future clinical treatment and improvement of symptoms of COVID-19.
