Applying Neonatal Finger (or Toe) Wrap Sensors:
 When you perform the measurement, position the sensor over the hand or foot with optical
components opposite each other.
 Hold the sensor, and insert stretched strap into slot, hold it there while threading end through
latch. If strap is too long, thread it through second latch.
 Connect the sensor with the monitor (or with the extension cable if needed).
3. Plug the connector of the sensor extension cable into the SpO

socket.
WARNING
Inspect the application site every two to three hours to ensure skin quality and correct
optical alignment. If the skin quality changes, move the sensor to another site. Change
the application site at least every four hours. For neonate, change the measuring site
every 20 minutes.
NOTE:
1 Injected dyes such as methylene blue or intravascular dyshemoglobins such as
methemoglobin and carboxyhemoglobin may lead to inaccurate measurements.
2 Inspect the sensor to ensure that the light emitter and receiver are aligned with each
other and there is no gap between the sensor and the finger. All the light emitted by
the light emitter must pass through the patient's tissue. The sensor cable should be
placed on the back of the hand.
3 Clean and remove any substances such as nail polish from the application site.
Periodically check to ensure that the sensor remains properly positioned on the
patient.
12.4 Measurement Limitations
Certain patient conditions can affect the measurements or cause the loss of the pulse signal.
