The Association Between Alveolar-Arterial Oxygen Tension Difference and the Severity of COVID-19 in Patients.

ABSTRACT:

Introduction

Coronavirus disease 2019 (COVID-19) emerged as a global pandemic and resulted in a significantly high death toll. Therefore, there is an urgent need to find a potential biomarker related to the disease severity that can facilitate early-stage intervention.

Methods

In the present study, we collected 242 laboratory-confirmed COVID-19-infected patients. The patients were grouped according to the alveolar to arterial oxygen tension difference (P_A-aO₂) value of COVID-19 infection after admission.

Results

Among the 242 laboratory-confirmed COVID-19- infected patients, 155 (64.05%) had an abnormal P_A-aO₂ value on admission. Compared with the normal P_A-aO₂ group, the median age of the abnormal P
