Abstract
Introduction: The data about pulmonary outcomes and recovery from COVID-19 are still limited.
Aims objectives: We aimed to find the rate of home oxygen treatment (OT) and factors affecting this requirement during follow-up.
Method: In this prospective study, patients who had been discharged on OT were enrolled and at the end of the 3 months categorized into two groups; group1 with partial oxygen pressure (paO2) <60 mmHg still require OT and group 2 paO2 ≥60 mmHg.
Results: There were total of 65 patients (table 1). Four patients died after discharged. 23 patients completed 3 months follow-up. 11 (group 1) still required OT and 12 recovered (group 2). Lymphocyte count was statistically higher in group 1 and PaO2 and SaO2 levels at admission were statistically lower in group 1 (table 1).
Conclusion: At the end of the 3 months nearly half of the patients still required OT. This requirement is not associated with radiological severity but may be with clinical and laboratory severity.
