To evaluate the efficacy of the Wayrachi continuous positive airway pressure (CPAP) non-invasive respiratory support device compared to the commercial high-flow cannula (CAF) for the treatment of patients with SARS-CoV-2. Study carried out at the Honorio Delgado Espinoza Hospital in Arequipa (Hospital COVID-MINSA Arequipa). The medical records of patients with SARS-CoV-2, of moderate or severe severity, who required non-invasive respiratory assistance, hospitalized in the internal medicine service during the 2nd wave of COVID in Peru, were evaluated. A survival analysis was performed considering days to death comparing Wayrachi with CAF. The effect of variables on death was explored using Cox regression. Results: 114 patients treated with Wayrachi (56.44%) and 88 with CAF (43.5%) were evaluated, observing a frequency of death of 34.2% and 34.1%, respectively. When comparing the frequency of death, or its survival, in both managements, no significant difference was observed (p=0.986 and p=0.928), this was maintained in the multivariate model. The Wayrachi CPAP had similar results to those presented by the commercial CAF equipment, which indicates it as an effective option for the management of COVID patients who require non-invasive respiratory support.
