Sentri Adult Nasal Cannula Filter Tube 2.1m 40pk

Cannulas that permit the sampling of exhaled carbon dioxide in non-intubated patients during the administration of supplementary oxygen. By delivering oxygen through one prong and sampling exhaled gas from the other, the nasal cannula 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.
