This Nasal Cannula permits end tidal Co2 sampling with simultaneous oxygen delivery.
Where analysis of PET CO2 and other exhaled gases is a standard medical practice in anesthesia, monitoring of nonintubated patients is limited. Supplemental oxygen, delivered by mask or conventional cannula, tends to dilute End Tidal gases and distort waveforms.
This special End Tidal sampling cannula permits an undiluted End Tidal gas sample, even with simultaneous insufflation of oxygen or gaseous analgesia. The result: A waveform equal to those obtained with the intubated patient!
