| T0, entering the operating room while breathing room air; T1, after 5 minutes of pre-oxygenation; T2, after successful endotracheal intubation; T3, safe apnea time up to 480 s or SpO down to 95%. Group M – pre-oxygenation with facemask; Group T – pre-oxygenation with THRIVE. Data are presented as mean±standard deviation. : Group M vs Group T; * # & | |||
