| Summary: | During the coronavirus disease 2019 pandemic, Ecuador reported a collapse of the healthcare system, in which intensive care unit beds were lacking. Therefore, we sought to determine whether the use of threshold expiratory positive pressure with an adult non-rebreather oxygen mask plus prone positioning is useful for improving oxygenation. Twelve patients were included. Eight patients (66.7%) survived, while four patients (33.3%) died. Baseline arterial oxygen saturation (%) prior placement median (interquartile range) 85.5% (80%–89%) and arterial oxygen saturation (%) post placement of the device was median (interquartile range) (93%–96%) (P = 0.0001). Respiratory rate before placement was median (interquartile range) 38 (36–42) and post placement of the device was median (interquartile range) 24 (22–30) (P = 0.0005). The use of an adapted device might be useful for the management of acute hypoxemic respiratory failure due to severe acute respiratory syndrome coronavirus 2 pneumonia, particularly when mechanical ventilators and high-flow oxygen systems are unavailable.
