Successful Application of Optiflow THRIVE to Restore Oxygenation and Facilitate Retrieval of an Aspirated Nut in a Severely Hypoxic Child: A Case Report.

In this case, the novel use of high-flow nasal oxygen successfully treated severe hypoxia by delivering oxygen through a very narrow space between the bronchoscope and the tracheal wall. Removal of a foreign body from a child's lung can be associated with hypoxia and cardiorespiratory arrest. The shared airway of the bronchoscope must allow surgical instrumentation and oxygenation. This simultaneous use can compromise gas exchange, leading to hypoxia. In this case, high-flow nasal oxygen supplemented bronchoscope oxygenation to treat a severely hypoxic child and facilitate subsequent removal of a peanut without further incident.
