Dual Nasal Cannula delivers oxygen to both nostrils via the lower ports and EtCO2 is sampled from both nostrils for sidestream or Microstream™ CO2 monitoring through the upper prongs. During exhalation, oxygen flow is diverted away for an accurate and reliable capnography trace.
Dual Masks and Nasal Cannulas simultaneously deliver supplementary oxygen and enable EtCO2 monitoring when using a sidestream or Microstream™ capnometer.
Guidelines1-7 require EtCO2 monitoring of all moderately or deeply sedated patients, for patients being recovered from anesthesia or moderate or deep sedation, and during CPR to monitor ET tube placement, efficacy of chest compressions and early indication of return of spontaneous circulation.
End-Tidal CO2 Monitoring & O2 Delivery
Delivering accuracy
with every breath
Dual Mask has been proven to be the most efficient in sampling
end tidal CO2 in an independent comparative study8 in a simulated patient.
