To evaluate the acute effects of types of response to the prone position (PP) in patients awake with COVID-19. Prospective, single-center study with 32 patients awake with COVID-19, with supplemental oxygen. The response to the prone position was performed for 30 minutes. After the test, they were instructed to remain on the PP daily, according to tolerance. The variables SpO2, heart rate, respiratory rate, ROX index, and ICU admission rate were recorded. A total of 25 patients (78.1%) responded to PP, with 13 (40.6%) showing persistent response and 12 (37.5%) transient. 7 patients (21.9%) did not respond. Patients with persistent and transient responses increased SpO2 (p <0.001), ROX index (p = 0.001 and p <0.001, respectively) and reduced heart rate (p = 0.01 and p = 0.02, respectively) and respiratory (p = 0.003 and p = 0.001, respectively), compared to the pre. There was no difference in all variables in patients who did not respond to PP. The rate of hospitalization in the ICU of patients who presented a persistent, transient response or who did not respond was 30.8% (4/13), 41.7% (5/12) and 57.1% (4/7), respectively. We can conclude that the patients who responded to PP showed a reduction in heart and respiratory rates, an increase in the ROX index. There was no difference in the hospitalization rate.
