Brief Summary

Healthcare systems around the world have been dealing with COVID 19. One of the main manifestations of this infection is lung involvement of varying degrees, causing a spectrum of diseases from mild lower respiratory tract infection to severe Adult Respiratory Distress Syndrome (ARDS). One of the important clinical parameters is to detect hypoxia early in order to initiate a higher level of care at the earliest. The presence of silent or latent hypoxia has made this task difficult in COVID 19. Besides, critical findings such as silent hypoxia that is not at rest but triggered by effort can be revealed by some practical field tests such as the 6-minute walk test or the 1-minute chair sit and stand test. Moreover, these simple tools also help to investigate the patient's readiness for discharge. In this way, it will be useful to evaluate their usability in discharge decisions or in determining the post-discharge cardiopulmonary reserves of the patients and therefore their rehabilitation needs. Although walk and performance tests can be performed naturally, safely and simply, more similarly to movements in daily living activities compared to cardiopulmonary exercise tests, the interest in these tests has increased over the years, especially in subjects such as exercise capacity, mortality and morbidity expectation, or oxygen desaturation in patients with chronic cardiopulmonary pathology. The number of studies in 19 patients is quite limited. For this reason, the necessity of new studies on different field tests to detect the presence of latent hypoxia, which expresses the oxygen desaturation triggered by effort, and to evaluate the exercise tolerance status before discharge, has been emphasized in recent reviews.The aim of this study is to determine the presence of silent hypoxia, which expresses the oxygen desaturation triggered by effort, in Covid-19 patients and to compare the different short-term walk and performance tests, which the investigators consider easier and applicable in the conditions of the pandemic environment, with the classical gold standard test ( Six minute walk test) in order to evaluate the exercise tolerance status of the patients before discharge.
