Association Between Body Mass Index and HFNC Therapy Success
Association Between Body Mass Index and HFNC Therapy Success
Patients over 18 years of age who are admitted to the Intermediate Care Unit of the Clinica
 del Country and the Clinica la Colina, with symptoms suggestive of severe pneumonia secondary
 to COVID-19 infection and acute hypoxemic respiratory failure. The primary outcome will be to
 determine the relationship between body mass index and high-flow cannula therapy success
 defined as: No need for mechanical ventilation.
All adult patients over 18 years of age admitted to the intermediate care service of the
 participating center with suspected SARS-CoV-2 pneumonia will be considered as potential
 candidates for the study.

 The medical records of patients in our cohort who require high-flow cannula therapy and who
 met all the inclusion criteria and none of the exclusion criteria will be reviewed.All data
 will be processed and analyzed using the SPSS 26 software once the study is completed. study
