title: Hypercapnia related to a faulty adult co-axial breathing circuit.
abstract: This report describes the appearance of CO2 on the capnograph during inspiration, which was linked to disconnection of the inner tube of a coaxial circuit extension piece. The increased use of coaxial breathing systems for adults makes inner tubes disconnections an important consideration when the CO2 appears during inspiration.
