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-section.
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.
