 If irritation such as skin reddening appears with the sensor use, change the attachment site or stop using the
sensor.
 Do not apply the sensor too tight. At the same time, check the blood flow constantly so that congestion is not
generated at the peripheral site.
 Do not use tape to attach the sensor.
 Even attachment for a short duration may inhibit the blood flow and generate compression necrosis or burn
injury. Also, blood flow inhibition may prevent correct measurements.
 Check the sensor attachment site constantly in every 4 hours when probes or reusable sensor are used, and at
least every 8 hours when single patient use sensors are used. Be especially careful of a patient with bad
perfusion. If the sensor attachment position is not changed constantly, skin irritation or skin necrosis due to
compression may be developed. For the patient with bad perfusion, check the sensor attachment position at
least every 2 hours.
 As skin for neonate, premature infant is immature, change the sensor attachment site more frequently
depending on the condition.
 Direct sunlight to the sensor area can cause a measurement error.Place a black or dark cloth over the sensor if
using in direct sunlight.
 When not measuring, unplug the relay cable and sensor from the SpO
2
connector. Otherwise, the outside light
may affect to falsely display measurements.
 The pulse wave is normalized for SpO
2
measurement, and does not indicate perfused blood volume. Check
proper probe attachment by observing the pulse wave.
 Precautions for Reusable Sensors
The light-emitting part of the sensor should be over the root of the fingernail or as instructed per the related
sensor instruction manual. Do not insert the finger too far into the sensor as it may hurt the patient. For details,
refer to the SpO
2
sensor instruction manual.
 Precautions for Single-Patient-Use Type Sensors
The sensor can be reused on the same patient as long as the adhesive tape attaches without slippage. But do not
reuse on other patients to avoid cross contamination. It is intended for single patient use only. For details, refer
to the SpO
2
sensor instruction manual.
 If "---" is displayed for the SpO
2
numeric data, make sure that the sensor is properly attached.
 Measuring on a limb with NIBP cuff, arterial catheter, or intracatheter may result in incorrect measurement.
 Venous congestion may cause under reading of actual oxygen saturation. Therefore, assure proper venous
outflow from monitored site. Sensor should not be below heart level (e.g. sensor on hand of a patient in a bed
with arm dangling to the floor).
Precautions about the NIBP Monitoring

Do not apply the NIBP cuff to site of injury. An injury may be worsened by the measurement.
 Do not apply the NIBP cuff to the arm on side treated axillary lymph nodes dissection. It may lead to lymphatic
edema by the cuff pressure.
 Measuring on a limb with SpO
2
sensor, arterial catheter, or intracatheter may result in incorrect measurement.
 An operator must not get away from a patient during the NIBP measurement. However, when getting away
from the patient is necessary, do not activate the Alarm Suspend and Silence functions in order not to miss any
sudden changes in the patient's condition.
 Pay attention when measuring the NIBP of patient with bleeding disorders or hyper coagulation. The cuff
inflation may cause petechia or circulatory failure by the blood clot.
 For the following situation, measurements will be terminated.
 When the measurement time has exceeded 160 seconds for adult and child, 80 seconds for neonate.
 When the inflation value has exceeded 300mmHg for adult, 210mmHg for child, and 150mmHg for neonate.
 If used with the incorrect patient classification, it will not only cause erroneous measurement, but the inflating
level for the adult may be applied to child or neonate causing dangerous situation to the patient.
 The continuous measurement and 1-minute interval measurement will automatically stop after 12
minutes (maximum 15 minutes).
 If the mean MAP display is set to OFF, the MAP alarm will not be generated. Also the MAP data will not be
displayed for the tabular trend or the NIBP list.
