calibration is finished and you can begin monitoring.
For intubated patients requiring an airway adapter: Install the airway adapter at
the proximal end of the circuit between the elbow and the ventilator Y-
For intubated patients with an integrated airway adapter in the breathing
circuit.: Connect the male luer connector on the straight sample line to the
female port on the airway adapter.
For non-intubated patients: Place the nasal cannula onto the patient.
For patients prone to mouth breathing use an oral-nasal cannula.
For nasal or oral-nasal cannulas with oxygen delivery, place the cannula on the patient as shown then
attach the oxygen supply tubing to the oxygen delivery system and set the prescribed oxygen flow.
Always connect the airway adapter to the sensor before inserting the airway adapter into the breathing
circuit. In reverse, always remove the airway adapter from the breathing circuit before removing the
Always disconnect the cannula, airway adapter or sample line from the sensor when not in use.
Using the Sidestream Sensor Holder
The holder delivered with the sensor can be used to clamp the sensor onto an IV pole or a shelf.
Push the sensor into the holder until it clicks into
