Evaluation of the response to prone positioning in awake patients with COVID-19

ABSTRACT This study aims to evaluate the acute effects of the responses to prone positioning (PP) in awake patients with COVID-19. A prospective, single-centered study, using supplemental oxygen, was conducted with 32 awake patients with COVID-19. The response to PP was performed for 30 minutes. According to their tolerance, the patients were instructed to daily remain in PP. The variables for oxygen saturation (SpO2), heart rate, respiratory rate, ROX index and intensive care unit (ICU) admission rate were registered. In total, 25 patients (78.1%) responded to PP, with 13 (40.6%) showing persistent response and 12 (37.5%) showing transient response. Seven patients (21.9%) did not respond. Patients with persistent and transient responses increased SpO2 (p
