Sentri is available in three sizes of nasal cannula and as an adult Intersurgical EcoLite™ mask. Both permit the sampling of exhaled carbon dioxide in non-intubated patients during the administration of supplementary oxygen. Various monitoring line configurations are available, please see product descriptions for the options.
By delivering oxygen through one prong and sampling exhaled gas from the other, the nasal cannula can provide end tidal values comparable to those achieved with intubated patients. Nasal cannula may be more appropriate for paediatric patients when high oxygen flows may “dilute” the CO2 sample and give a low (or no) value. A facemask may be more appropriate when the nares are occluded or obstructed
