Colibri coloriometric technology rapidly detects oesophagal intubations


Rapid verification of correct placement is extremely important [1,2]. We have tested a new coloriometric CO2 detection indicator meant for this purpose [3].


An entdotracheal tube was placed both in the trachea and the oesophagus in otherwise healthy patients undergoing elective surgery under general anaesthesia. We compared the four first ventilations of the endotracheal and oesophageal tube using capnography and a Capno Bri indicator with four different colour gradings. (Blue ~ 0.5%, dark green ~ 1.0%, light green ~ 3.0% and yellow ~ 4.0%)


In all patients (n = 9), the indicator confirmed correct placement of the tube in the trachea at the first ventilation (yellow color). The indicator also verified incorrect oesophageal placement at the first ventilation in all patients (blue color).

These results were confirmed by the capnography.


The Colibri technology is a reliable technique for confirmation of correct endotracheal tube placement. It may be especially suitable in emergency situations where capnography is not available
