Any colouring agent present in the blood (e.g. for performing diagnostic tests), such
as methylene blue, indocyanine green, indigo carmine, patent blue-V (PBV), can
compromise the accuracy of oximetry readings.
Any condition that restricts the flow of blood, e.g. the use of a cuff to measure blood
pressure, can compromise the accuracy of SpO2 and pulse rate readings.
False nails and nail varnish must be removed before using the sensor as they might
compromise the accuracy of oximetry readings.
Significant levels of dysfunctional haemoglobin such as carboxyhemoglobin or
methemoglobin affect the accuracy of oxygen readings.
If two or more oximetry sensors are positioned near each other, optical interference
may occur. Such interference can compromise the accuracy of oxygen readings. To
eliminate any such interference, cover the sensors with an opaque material.
Dirt or obstructions that block the red light on the sensor or that block the detector
may provide inaccurate readings or sensor malfunctions. Always make sure that the
sensor is clean and free of obstructions.
Never place the sensor in an autoclave. Do not sterilise the sensor.
Before cleaning the sensor, disconnect it from the spirolab unit to prevent damage
to the sensor and device and to avoid compromising user safety.
1.2.5
USB connection cable
Incorrect use or application of the USB cable may produce inaccurate measurements,
which will show very inaccurate values of the
patient’s condition. Carefully inspect each
cable before use.
Do not use cables that appear to be or are damaged. If a new cable is required, contact
your local distributor.
Use only cables supplied by MIR, specifically designed to be used with Spirolab. The use
of other types of cables can lead to inaccurate measurements.

All the maintenance operations described in the User Manual must be carried out
with great care. Failure to follow these instructions may lead to incorrect readings
or the incorrect interpretation of readings that have been taken.
Do not modify the device without authorisation from the manufacturer.
All modifications, adjustments, repairs and reconfigurations must be performed by
the manufacturer or by personnel authorised by the manufacturer. In the event of
problems, do not attempt to make repairs. The setting of configurable parameters
