After having measured the SpO2i/RRi values in COVID-19 patients, we compared them to those of non-COVID-19 patients (i.e., patients with other causes of ARF treated by the BLS teams over the previous 3 years in the same period). In summary, this retrospective study based on prehospital first responder data highlighted a relatively higher discrepancy between SpO2i and RRi in COVID-19 ARF patients, in comparison with previous non-COVID-19 ARF patients.
