Applying sensors
•
Use dry and clean sensors only.
•
Clean the application site. Remove nail polish, artificial
fingernails, earrings etc.
•
Clip long fingernails.
•
Attach the sensor cable to the wrist or bedclothes to prevent the
cable and sensor from moving.
NOTE: Datex-Ohmeda sensors are latex-free.
WARNING: Change measuring site frequently. Change
sensor site and check skin and circulatory status every
2 to 4 hours with adults and every hour with small
children.
WARNING: To prevent erroneous readings, do not use
physically damaged sensors, sensor cables or modules.
Discard a damaged sensor or sensor cable
immediately. Never repair a damaged sensor or cable;
never use a sensor or cable repaired by others. A
damaged sensor or a sensor soaked in liquid may cause
burns during electrosurgery.
WARNING: Inaccurate SpO
2
data can result if a sensor
is past its useful life. Therefore, re-evaluate the
measurement periodically by performing additional
assessment of the patient and equipment, including
consideration of use of alternate monitoring methods
such as direct measurement of arterial oxyhemoglobin
saturation (SaO
2
).
Displaying pulse rate
The heart rate can originate from various sources. Displaying the
pulse rate measured with pulse oximetry:
1. Press the
Others
key and select SpO2 Setup .
2. Select HR Source - Pleth .
Measurement limitations
−
The pulse oximeter cannot distinguish between oxyhemoglobin
and dyshemoglobins, for example, met- or carboxyhemoglobins.
−
Poor perfusion may affect the accuracy of measurement when
using the ear probe.
−
If possible, do not attach the SpO
2
sensor to a limb that is used
for non-invasive blood pressure measurement or for
administrating cold infusions.
WARNING: Conditions that may cause inaccurate
readings and impact alarms include interfering
substances, excessive ambient light, electrical
interference, ventricular septal defects (VSD),
excessive motion, low perfusion, low signal strength,
incorrect sensor placement, poor sensor fit, and/or
movement of the sensor on the patient.
Adjusting SpO
2
settings
You can adjust the volume of the beat sound, the waveform scaling
and response averaging time:
1. Press the
Others
key.
2. Select SpO2 Setup and Beat Sound Volume, Pleth Scale or
SpO2 Response .
