Simple but Significant Modifications of High-Flow Nasal Cannula

High-flow nasal cannula (HFNC) is one of the most commonly used devices for oxygen therapy during the coronavirus disease 2019 (COVID-19) pandemic in different hospital settings. Multiple alternative options include non-invasive and invasive ventilation. But non-invasive ventilation is very uncomfortable for patients, and weaning from invasive ventilation in a patient with lung pathology is challenging. Hence, HFNC has come up as a safe alternative that averts invasive ventilation. However, its widespread application is difficult in patients with nasal deformities. We discuss two patients, one with caudal dislocation of the nasal septum with a crooked nose and the other patient with septal hypertrophy. In both cases, invasive ventilation was deferred, and target oxygen saturation was achieved after a simple dispositive modification.
