Descriptive review. Med. crít. (Col. Mex. Med. Crít.) [online]. 2022, vol.36, n.6, pp.378-386.  Epub 18-Ago-2023. ISSN 2448-8909.  https://doi.org/10.35366/107461.

In December 2019, several people with pneumonia of unknown cause were linked to a seafood market in Wuhan, China. With the discovery of a new type of coronavirus and the initiation of the COVID-19 pandemic, the most common symptoms manifested by patients consists of a flu syndrome, the severe illness generally occurs one week after the onset of symptoms. The severity of the picture is characterized by dyspnea, tachypnea and decreased oxygen saturation. In Mexico there have been approximately 3’684,242 total cases and 279,104 total deaths from COVID-19, up to epidemiological week number 40, being one of the countries with the highest mortality at the international level, 5-10% of patients infected by SARS-CoV-2 virus will require management in the intensive care unit, with the need for supplemental oxygen, hospital mortality in Mexico has reached 73.7%. The limits of hypoxemia that indicate the need for oxygen therapy are an arterial partial pressure of oxygen (PaO2) less than 60 mmHg. It is necessary for the specialist in critical patients to know the different interfaces and modes of oxygen administration, the administration of oxygen in patients with COVID-19 and hypoxemic respiratory failure must be appropriate and pertinent.

Palabras llave : non-invasive oxygen therapy; respiratory failure; COVID-19.
