I. GENERAL WARNINGS AND CAUTIONS
CONTRAINDICATION: Do not use with reflectance or ear clip sensors. Use only with transmittance type,
finger or toe sensors.
WARNING: FingerSims are fragile and must be handled with care, they contain glass.
CAUTION: Federal law restricts this device to sale by or on the order of a physician.
CAUTION: The movement of the FingerSim relative to the oximeter sensor may cause erroneous pulse rate
and/or oxygen saturation readings. Use the FingerSim Holder to facilitate pulse generation
without introducing FingerSim™ movement relative to the oximeter sensor.
CAUTION: Do not use a FingerSim that is cracked or leaking fluid.
CAUTION: Avoid extended exposure to sunlight.
CAUTION: The SpO2 simulation by the FingerSim is temperature dependent. See Charts 6, 7 and 8 for the
appropriate adjustment. Allow at least one-hour stabilization at room temperature before using.
CAUTION: Do not store the FingerSim outside the recommended Long Term Storage Temperature range
(32°F-104°F). NOTE: Temperatures outside this range for short duration are acceptable (for
example during shipping).
CAUTION: When testing flexible sensors, ensure the emitter and detector are vertically aligned on opposite
sides of the FingerSim.
CAUTION: Do not use beyond the calibration date.
CAUTION: No test system can simulate all possible operating conditions a pulse oximeter may encounter. Use
the FingerSim as an adjunct to other indications to determine proper pulse oximeter operation.
CAUTION: Improper insertion of the FingerSim into the Holder can cause breakage. Insert the Phantom as
shown in Figure 7.
II. PURPOSE
The FingerSim Pulse Oximeter Test System enables the healthcare professional to evaluate pulse oximeter and
sensor function at three simulated light absorption conditions. These absorption conditions are set to simulate a
typical finger at nominally 97%, 90%, and 80% SpO
pulse amplitudes and rates can be simulated.
Before the availability of the BC Biomedical FingerSim, pulse oximetry systems (oximeter plus sensor) were not
easily tested. The oximeter’s measurement of the small pulsatile blood component and the interrelationship of the
oximeter calibration curve with the light emitting characteristics of the sensor made a true oximeter system tester
difficult to conceive. The BC Biomedical FingerSim System, when used as an adjunct to other indicators, aids
the healthcare professional in assessing performance of both oximeter and sensor.
CONTRAINDICATION: Do not use with reflectance or ear clip sensors. Use only with transmittance type,
finger or toe sensors.
CAUTION: No test system can simulate all possible operating conditions a pulse oximeter may encounter. Use
the FingerSim as an adjunct to other indicators to determine proper pulse oximeter operation.

III. DESCRIPTION
The BC Biomedical FingerSim system provides a rapid, inexpensive and convenient means of assessing the
function of the entire pulse oximeter system including the oximeter sensor. A set of three FingerSims are
included in each kit. Each of the three FingerSims contain a fluid with precisely controlled light absorption
characteristics sandwiched between two glass slides. The concentration of the substances in the three mixtures
allow the FingerSim™ to mimic the light absorbing qualities of arterial blood as measured by an oximeter at
different oxygen saturation values (nominally 97%, 90%, and 80%). The 97%, 90%, and 80% FingerSims are
easily identified by the color coded end caps (Red - 97%, Blue - 90%, and Black - 80%).
Squeezing the colored coded flat end will produce a pulsatile movement of the solution. This pulsation is detected
as a pulse by the oximeter system being tested, and thus allows the oximeter to calculate and display an SpO
value

which corresponds to the fixed light absorbing characteristics of the particular FingerSim being used.
