4. Pulse rate (PR): pulse rate measured every minute.
5. %: blood oxygen unit.
6.4.2 Safety Information
Warning

Only the blood oxygen sensor specified in the User manual is allowed; and it should be used by
following all warnings and warnings specified in the User manual.

In case of any damage to the packing of the sterilization-marked blood oxygen sensor, please
discontinue use and contact the sensor supplier.

An oximeter should be used for analyzing blood samples in case the animal is likely to be
oxygen-deficient to get a more complete understanding of the animal
’s condition.

Any use of the monitor and its sensors while an NMR equipment is in use should be avoided, lest
any serious burn is caused by inductive currents.

Adhesion positions of sensors should be checked once every 2 hours while long-time continuous
monitoring for animals are being conducted and should be properly moved when skin condition
changes or every 4 hours. More frequent examinations may be necessary for some animals, such
as animals < 10 kg and perfusion-difficult or skin-allergic animals. Long-time continuous monitoring
will possibly add some unpredictable changes on skin, such as allergy, reddening, blistering or
pressure necrosis, etc.
Attention

Tongue should be correctly placed into the sensor (as referred to relevant drawings in the User
manual).Inappropriate placement will produce inaccurate measure.

Improper securing of blood oxygen sensor with adhesive tape will yield venous pulse, which may
cause inaccurate SpO

measure.

Clear any ray-barring obstacle along the light path.

Strong light beams and electromagnetic interference in the area and excessive amount or level of
animal
’s activity may lead to wrong readings of the monitor.

When blood oxygen sensors are used, be cautious to shield external optical source, such as optical
beams for heat therapy or from infrared lamps, otherwise interference may be introduced to the
measure.

It is possible that accurate blood oxygen measuring results are not available in case of shock, low
temperature or use of vaso-active drugs as well as in the case of existence of carboxyhemoglobin,
methemoglobin, methylene blue, cyanine green, indigo carmine and other substances.

When non-invasive blood pressure and blood oxygen are simultaneously measured, please make
sure that blood oxygen sensor and the non-invasive blood pressure cuff are not placed on the same
limb, since non-invasive blood pressure (NIBP) measure will block blood flows, affecting the blood
oxygen measure.
