Can intubation confirmed by capnography be misleading? Complication with rabbit intubation

Abstract

Rapid and accurate tracheal intubation in rabbits is challenging. It requires skill and is a technically demanding procedure. Visualisation of a normal capnography trace is widely considered the most objective indication of a correct orotracheal intubation, especially with blind intubation and small tidal volumes. This case report describes how a large defect in the oesophageally dislocated endotracheal tube led to misleading positive capnography signal.
