A (b)(6) in respiratory distress had been at 100% oxygen saturation on heated high flow nasal cannula on 100% fio2 at 5 l, temperature was 37c.At approx 1600, the high flow nasal cannula dropped the fio2 to 21% (room air) and started to alarm.The equipment and connections were verified and everything was secured and connected.The rn was unable to change the fio2 setting to 100% and the high flow nasal cannula continued to alarm.Respiratory therapist was called, and blow by oxygen was administered to the infant.The infant saturations dropped from 100% to 89% and was progressively more tachypneic.The neonatologist came to the bedside to assist as the infants saturations dropped to the 60's.The neonatologist bagged the infant and saturations corrected to high 90's, while respiratory therapist quickly replaced the high flow nasal cannula with a new high flow nasal cannula.The infant remained tachypneic but stable on the new high flow nasal cannula on 5l, fio2 100%, temperature was 37c.
