it can be used to demonstrate that a particular monitor reproduces a calibration curve
that has been independently demonstrated to meet a particular accuracy.
5 If the surrounding temperature increases, the operator should pay attention to the site
of poor perfusion, and increase the frequency of checking the skin and changing the
measurement site to prevent burns. If the initial skin temperature is less than 35 °C,
the temperature of all the listed sensors on the skin will not exceed 41 °C during
working.
6 The cumulative use time for SpO

sensor in a single patient should be less than 30
days.
12.3 Measuring SpO
2
1. Select the correct patient category setting (adult/pediatric and neonatal), as this is used to
optimize the calculation of the SpO
2
and pulse numerics.
2. During measurement, ensure that the application site:
– has a pulsatile flow, ideally with a good circulation perfusion.
– has not changed in its thickness, causing an improper fit of the sensor.
Measurement Procedure
1. Switch on the monitor.
2. Attach the sensor to the appropriate site of the patient.
Before Applying the Sensor
Be sure to understand all warnings listed in the previous section before applying any sensor to a
patient. Also,check the sensor as follows:
 Check the sensor outside and inside. To inspect the inside, gently open the sensor cavity and
check splits on or next to the transparent silicone that covers the optical elements.
 Any sensor showing signs of damage or alteration must not be used for further patient
monitoring; instead, dispose of it using proper disposal procedures.
Applying Finger/Soft-tip Sensors:
 Nip the clamp, and choose a site that is well perfused and restricts a conscious patient‘s
movements least. The right finger of the non-dominate hand is preferred. Alternatively, the
other digits on the non-dominate hand may be used.
 The grate toe or long toe (next to the grate toe) may be used on restrained patients or patients
whose hands are unavailable.
 Place the finger into the sensor according to the direction of the symbol on the sensor. The
fleshiest part of digit should be covering the detector window.
 Orient the sensor so that the cable will be running towards the top of the patient‘s hand.
 Connect the sensor with the monitor (or with the extension cable if needed).
