Monitoring

z
To ensure patient electrical isolation, connect only to other equipment
with electronically isolated circuits.
z
Do not connect to an electrical outlet controlled by a wall switch or
dimmer.
z
Carefully route patient cabling to reduce the possibility of patient
entanglement or strangulation.
z
Interfering Substances: Carboxyhemoglobin may erroneously increase
readings. The level of increase is approximately equal to the amount of
carboxyhemoglobin present. Dyes, or any substance containing dyes,
that change usual arterial pigmentation may cause erroneous readings.
z
Do not use this instrument and the sensors during magnetic resonance
imaging (MRI). Induced current could potentially cause burns. The
monitor may affect the MRI image, and the MRI unit may affect the
accuracy of the oximetry measurements.
z
The SpO
2
value might be overestimated in the presence of Hb-CO,
Met-Hb or dye dilution chemicals.
z
Verify sensor cable fault detection before beginning monitoring. Unplug
the SpO
2
sensor cable from the connector. The screen displays the
prompt information “SPO2 SENSOR OFF” and the audible alarm is
activated.
z
Do not use the supplied sterile SpO
2
sensors if the packaging or the
sensor is damaged. Return them to the distributor or manufacturer.
z
Do not perform SpO
2
and NIBP measurements on the same limb
simultaneously. Obstruction of blood flow during NIBP measurements
may adversely affect the reading of the SpO
2
value.
z
Prolonged and continuous monitoring may increase the risk of burns at
the site of the sensor. It is especially important to check the sensor
placement, and ensure proper attachment on neonates and patients of
poor perfusion or skin sensitive to light. Check the sensor location every
2–3 hours and move to another location if the skin deteriorates. More
frequent examinations may be required for different patients.
NOTE
z
Place the SpO
2
sensor cable at the backside of the patient hand. Make
sure the patient nail is just opposite to the light emitted from the sensor.
