In a large number of cases, COVID-19 has been shown to cause pneumonia which severely affects both lungs. It was also observed that, in its acute phase, it can produce persistent inflammation or pulmonary embolism, as well as clots in the pulmonary arteries. These complications, as in other viral pneumonias, may cause respiratory complications in the medium and long terms, once COVID-19 is overcome.
Thus, patients who suffer from respiratory complications after COVID-19 will be subjected to a chest CT scan and pulmonary tomography - to see in detail whether these lesions are present - and a pulmonary function test - to check whether the lung capacity was affected.
In addition, some patients may need to do a stress test, an echocardiogram and a blood test, depending on the complications that each patient presents at the time.
