Jon-Emile S. Kenny MD [@heart_lung] That high flow oxygen applied via nasal cannula lends itself to treating hypoxemic respiratory failure may be obvious. With adequate heat and humidification, oxygen can be employed relatively comfortably at very high flow rates – upwards of 60 L/min – to the nares. At such rates, the effort of the patient is minimized and much less ambient air is entrained. Accordingly, precise fractions of inspired oxygen may be delivered up to 1.0. Further, the high flow of oxygen creates positive end-expiratory pressure [PEEP] and recruits end-expiratory lung volume [
