Abstract
The successful use of Transnasal Humidified Rapid‐Insufflation Ventilatory Exchange (THRIVE) has up to now only been reported in small groups by dedicated teams.

We report its effective use in 105 cases having upper airway endoscopy cared for by a variety of surgeons and anaesthetists.

THRIVE still has a failure rate of between 3 and 6% and clinicians need to have a Plan B to effectively oxygenate the patient.

Causes of failure are multifactorial but obesity is one statistically significant factor identified by our work.

Ninety‐five percent of our patient cohort could successfully be oxygenated for 20 minutes
