Effect of Respiratory Exerciser on Pulmonary Functions of COVID-19 Patients

COVID-19 infection is the cause of the current pandemic, responsible for loss of life and disability at a rate unseen before. Among survivors, the infection may cause lasting damage, such as permanent loss of lung function. This study aims to investigate if pulmonary rehabilitation done via supportive devices may reduce or prevent lung function injury. Patients will be chosen among COVID-19 patients who require hospitalization. Patients then will be divided into two groups, those who had used said devices, and compare them to those who had not used them for any reason. After a month, two groups will be evaluated by respiratory function tests, which are expected to provide the results required for a proper comparison. Pulmonary rehabilitation provided by the supportive devices is expected to either lessen or eliminate a loss of pulmonary function over time, compared to the group who did not use them.
