With an increasing understanding of respiratory physiology and pathology, many new oxygen delivery devices have been introduced lately. Among them, high flow nasal cannula (HFNC) seems a promising modality that can deliver heated and humidified flows higher than the peak inspiratory flow at high FiO2 (fractional inspired oxygen), hence decreasing the work of breathing without causing discomfort to the patient. Applications of HFNC have escalated for use in multiple areas besides perioperative period over the last decade. The use of HFNC in obstetric population is particularly intriguing as this population is at risk of adverse airway related events. Hence, this narrative review focuses upon the role of HFNC for pre-oxyenation of pregnant patients in peripartum and in intensive care units. We have reviewed the current state of knowledge and the future prospects of HFNC use in obstetric setting.
