AbstractCOVID-19 pandemic has seen an unprecedented number of patients presenting with acute respiratory distress syndrome to the intensive care units all over the world. Between August and November 2022, we performed research on PubMed screening all publications on COVID-19 disease and respiratory failure and its treatment. In this review we focused on COVID-19 most common manifestations concerning lung function. The respiratory infection develops in three broad phases: early, intermediate, and late. The mainstay of the disease is the frequent presence of severe hypoxemia associated - at least at the beginning - to a near normal lung mechanics and PaCO2 tension. The management of symptomatic patients, progressing through these temporal phases, is not possible without understanding the pathophysiology underlying the respiratory manifestation.
