Disposable Colorimetric Carbon Dioxide Detector Use as an Indicator of a Patent Airway During Noninvasive Mask Ventilation

Colorimetric carbon dioxide detectors are useful indicators of proper endotracheal tube placement. We have found that they also are helpful during bag and mask ventilation as an indicator of a patent airway. In this report, we describe our experience with these devices for use during preintubation airway stabilization as observed during videotaped performances from a prospective, randomized trial of intubation premedication.
