<p>An intubation detector for an endotracheal tube has a resilient bellows and a carbon dioxide, color-change indicator mounted at the machine end of the tube. Compressing and releasing the bellows indicates whether or not the patient end of the tube is occluded. When the patient end of the tube is not occluded, gas is drawn into the indicator by the bellows to provide an indication of carbon dioxide level. The detector may be mounted at the machine end of a stiff introducer tube extended along the endotracheal tube. Alternatively, the detector may be mounted by a stem directly into the bore at the machine end of the endotracheal tube.</p> |
