2 Overview

SpO2 stands for Peripheral capillary oxygen saturation. It is an
estimation of the oxygen saturation level in your blood. Oxygen
saturation is defined as the ratio of oxyhemoglobin to the total
concentration of hemoglobin (i.e. Oxyhemoglobin + reduced
hemoglobin) present in the blood. SpO2 is an important
bio-parameter. A number of diseases relating to the respiratory
system may cause a decrease of SpO2 in blood. Homeostasis
failure and surgery complications may only lead to a reduction of
oxygen supply to the human body. This could lead to vertigo,
impotence, emesis and in severe hypoxia, coma and death.
Therefore, prompt information of patients' SpO2 is helpful to a
doctor to anticipate potential danger and is of great importance in
the clinical medical field.
The Pulse Oximeter feature herein is small, portable, non-invasive,
easy to use and requires little power. The user only needs to insert a
finger into the probe for SpO2 and Pulse Rate measurement.

3 Principle

Oxygenated blood absorbs light at 660nm (red light), whereas
deoxygenated blood absorbs light preferentially at 940nm
(infra-red). Pulse oximeters consist of two light emitting diodes,
at 600nm and 940nm, and two light collecting sensors, which
measure the amount of red and infra-red light emerging from
tissues traversed by the light rays. The relative absorption of light
by oxyhemoglobin (HbO) and deoxyhemoglobin is then
processed according to the Beer-Lambert's law and an oxygen
saturation level is reported. The device directs its attention at
pulsatile arterial blood and ignores local noise from the tissues.

The result is a continuous qualitative measurement of the patients’

oxyhemoglobin status. Oximeters deliver data about pulse rate,
oxygen saturation (SpO2) and cardiac output.

The use of pulse oximeters is limited by a number of factors:
Abnormal movement, such as occurs with agitated patients, will
cause interference with SpO2 measurement. Low blood flow,
hypotension, vasoconstriction and hypothermia will reduce the
pulsatility of capillary blood, and the pulse-oximeter will
under-read or not read at all. Conversely, increased venous
pulsation, such as tricuspid regurgitation, may be misread by the

Figure 1.

Innovo® CMS 50F PLUS User Manual

6

pulse-oximeter as arterial blood, with a low resultant reading.
Finally, it is generally accepted that the saturation percentage is
unreliable on the steep part (around 60 mm Hg) of the
oxyhemoglobin dissociation curve.

The Acc U Rate® SnugFit probe attempts to ameliorate some of
the problems by

1) Fitting snugly without causing discomfort to the user’s finger

even under prolonged use. This allows reliable measurement of

user’s Pulse Rate and SpO

during sleep and/or exercise.

2

2) Increasing the sensitivity of the sensor/receipt tube (See Figure

3) so that it can measure user’s SpO

and Pulse Rate (PR) with

2

precision even at low blood perfusion.

4) Blocking ambient light from reaching the sensor/receipt tube in
(See Figure 1) that might affect the precision and reliability of the
readings.

constant, stable reading. In other words, the wavelength and

amplitude of each wave will be identical to the next (Figure 6).
F. You may now read the SpO2 and PR displayed on the OLED

screen.

ATTENTION

The Fingernails should be facing the LED lights and not

the sensor

Make sure that your finger is put deep into the probe

such that the fingertip is directly in between the LED
sensor and the LED light source.

Make sure your finger is stationary in the probe while

you are measuring your SpO2 levels.

Excessive ambient infra-red light, especially for people

who use the pulse oximeter in an overly bright lit room
can interfere with the sensor.

Poor circulation can affect oximeter readings. Warm

your hands and fingers before taking your
measurements. Remember your pulse oximeter is
measuring your SpO2 and PR based on your blood flow.
If the blood flow in your finger drops below a certain
level, the pulse oximeter will not be able to function.

If the alarm function is on, a medium-priority alarm will

go off when the probe does not register a reading (like
when the finger is out). User will hear an intermittent
beeping sound and a "FINGER OUT" message will be
displayed across the user interface. Medium priority
alarms indicate that prompt operator response is
required.

6.2 Cautions
A. Please check device before use to confirm that it is working

normally. The SpO2 and PR should be displayed correctly on the
screen.
B. The finger should be place in between the LED lights and
the sensor (see Figure 1 and 5 for reference), or it may result in
inaccurate measurement.
C. The SpO2 sensor should not be used on an arm with a blood
pressure cuff or undergoing intravenous injection. It should not be
used on the arterial canal too.
D. Do not fix the SpO2 sensor with adhesive as it might lead to
inaccurate measurement of the SpO2 and pulse rate.
E. Excessive ambient light may affect measuring result
although the Acc U Rate® SnugFit probe is designed to minimize
such interference. Ambience light includes, but is not limited to
fluorescent lamp, dual ruby light, infrared heater, direct sunlight
and LED lights.
F. Strenuous activities or extreme electrosurgical interference
may affect accuracy pf device.
G. User should not use enamel or other makeup to ensure
accuracy.
H. Please clean and disinfect the device according to
instructions outlined in Chapter 7.1 of the user manual.

6.3 Clinical Restrictions
A. As the accuracy of the device is based on the arteriole blood,

an adequate amount of blood flow is required. The SpO2
waveform (Plethysmography) will decrease for users with a weak

Innovo® CMS 50F PLUS User Manual

20

pulse due to shock, low body temperature, major bleeding, or use
of vascular contracting drug. Under such circumstances, the
measurement will be more sensitive to interference.
B. For users with a substantial amount of staining dilution drug
such as methylene blue, indigo green and acid indigo blue, carbon
monoxide hemoglobin (COHb), methionine (Me+Hb),
thiosalicylic hemoglobin or icterus, the SpO2 readings may be
inaccurate.
C. Drugs like dopamine, procaine, prilocaine, lidocaine and
butacaine may also affect the accuracy of SpO2 measurement.
D. Patients with serious anemia may also report good SpO2
measurement.
If you think that the above conditions apply to you, please consult
a physician.

NOTE 1 At 80 MHz and 800 MHz, the higher frequency
range applies.
NOTE 2 These guidelines may not apply in all situations.
Electromagnetic propagation is affected by absorption and
reflection from structures, objects and people.

a

Field strengths from fixed transmitters, such as base stations

for radio (cellular/cordless) telephones and land mobile
radios, amateur radio, AM and FM radio broadcast and TV
broadcast cannot be predicted theoretically with accuracy.
To assess the electromagnetic environment due to fixed RF
transmitters, an electromagnetic site survey should be
considered. If the measured field strength in the location in
which the CMS50F(W) PLUS Pulse Oximeter is used
exceeds the applicable RF compliance level above, the
CMS50F PLUS Pulse Oximeter should be observed to
verify normal operation. If abnormal performance is
observed, additional measures may be necessary, such as
reorienting or relocating the CMS50F PLUS Pulse
Oximeter.

Over the frequency range 150 kHz to 80 MHz, field strengths

should be less than 3 V/m.
