Oxygen is delivered 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.

DualGuard delivers reliable O₂ delivery and monitors CO₂ from both the mouth and nose simultaneously, improving patient safety while fulfilling regulatory guidelines.

CapnoCare™ samples EtCO₂ during critical situations and can be used with a resuscitation bag for intubated patients, a laryngeal mask, or an anesthesia face mask.
