COVID-19 emerged as a pandemic, after its outbreak in Wuhan, China in December 2019. It is caused by a new type of Coronavirus, which binds to ACE-2 receptors on Type 2 pneumocytes in the lower respiratory tract. The clinical presentation of patients with COVID-19 varies from asymptomatic disease to severe acute respiratory distress syndrome (ARDS).<unk>  is present with an increased A-a gradient.<unk>  is diagnosed by Pa02<60mmHg in a sample of Arterial Blood Gas. Mechanisms involved in<unk>  are widely reported to be due to ventilation perfusion mismatch and intrapulmonary shunting. Diffusion impairment can cause<unk>  during recovery period due to fibrosis in the lungs. Older age, male sex, hypertension and dyspnea have been identified as risk factors for development of<unk>  in COVID-19. Complications of<unk>  include acute respiratory failure and multi-organ failure. Treatment is based on oxygen supplementation to keep target Spo2> 90%.
