Cerebral Neonatal Single-Use Regional Oxygen Saturation Sensor (English GB) Page 2
INSTRUCTIONS FOR USE
Pre-use Check: Remove the sensor from the package and examine for visual signs of damage. If any signs of
damage are observed, select another sensor.
Cerebral Site Selection: Select sensor site on the right or left side of forehead. Placement of the sensor in other
cerebral locations, or over hair, may cause inaccurate readings, erratic readings, or no readings at all. Do not
place the sensor over nevi, sinus cavities, the superior sagittal sinus, subdural or epidural hematomas or other
anomalies such as arteriovenous malformations, as this may cause readings that are not reflective of brain tissue
or no readings at all.

Cerebral Placement:
Patient Prep: To achieve optimum adhesion, the patient’s skin must be clean and dry. Dry skin with a gauze pad.
Warm the sensor in your hands or an incubator to ease placement. Then, remove the liner and apply sensor to
patient.
Sensor Placement: Holding the cable, peel back white liner from thin, clear adhesive beginning at the point where
the cable meets sensor pad. Apply to the skin. Continue applying the sensor by smoothing it to the skin from the
center outward. Ensure edges of the sensor are sealed.
Monitoring: Plug the sensor cable into the preamplifier connector. Secure the sensor cable to a fixed object to
avoid strain on the sensor-to-skin interface using strain-relief clips. Ensure the cable is properly inserted into the
preamplifier. Calibration is automatic and monitoring will begin in seconds.
Status messages on the INVOS System display will appear if monitoring conditions are compromised. Periodically
check skin integrity according to your institution’s patient care protocol. If sensors are removed or peeled back to
do so, be sure sensor is properly re-sealed to skin to avoid light entering. For extended monitoring,
Covidien
recommends using a new sensor every 24 hours or if adhesive is inadequate to seal the sensor to the
skin.
