“…Ten studies identified respiratory symptoms, specifically tachypnea at >25 breaths per minute and oxygen saturation at <90%, as the top triggers for RRT activation (Byrne et al, 2021;Churpek et al, 2017;Considine et al, 2017;Currey et al, 2022;Fernando et al, 2019;Lyons et al, 2019;Sebat et al, 2020;Shappell et al, 2018;Tirkkonen et al, 2017;Viana et al, 2021). The RRT was also activated for new-onset breathing difficulty, bradypnea, acute respiratory distress, chronic respiratory disease, and complex respiratory failure (Byrne et al, 2021;Fernando et al, 2019;Lyons et al, 2019;Na et al, 2020;Orosz et al, 2020;Shappell et al, 2018;Smith et al, 2017;Tirkkonen et al, 2017;Viana et al, 2021). Cardiovascular was the second most common activation category, with six studies identifying these issues as the top concern for RRT activation (Kim et al, 2021;Na et al, 2020;Padilla & Mayo, 2019;Sebat et al, 2020;Shoaib et al, 2021;Smith et al, 2017).…”
