In order to achieve precise and reliable
measurements, it is important to be familiar with
the operation of the device and information on
pulse oximetry. Please read this operating manual
carefully!
Pulse oximetry is a process for non-invasive
measurement of arterial blood oxygen saturation
as well as the pulse rate and pulse intensity on a
human finger. The oxygen saturation determined
in this way is referred to as SpO2 (saturation of
peripheral oxygen) and specifies the content of
haemoglobin saturated with oxygen in percent.
What is pulse oximetry?

Oximeter BSM 382 and for your trust in
our products. To ensure proper functioning and
performance of your pulse oximeter, please read
the operating manual prior to using your device
for the first time. This is to ensure that you can
enjoy this article for a long time.

Photocell (infrared light receiver) Fig. 1
Infrared transmitter
The Pulse Oximeter BSM 382 is a portable
measuring device for easy, uncomplicated and
precise measurements of arterial oxygen
saturation as well as pulse rate and pulse intensity
(display as bar and wave chart) at any time. The
device features an adjustable acoustic and visual
alarm function.
Using the Pulse Oximeter BSM 382, the oxygen
saturation level of the arterial haemoglobin
(SpO2) can be easily measured on a finger. The
measurement is carried out by two light sources
with different wavelengths being shone through
the finger and hitting a photo electrode on the
other side. The photo electrode determines which
portions of the light have passed through the
finger. Depending on the blood oxygen saturation,
different portions of the light pass through the
finger. Based on these measurements, the device
determines the saturation level, making blood
samples unnecessary.

This device is exclusively intended for private use.
It is not suitable for commercial application or
long-term monitoring.
2.2 Pulse Oximeter BSM 382 fields of
application
Principle of operation:
The Pulse Oximeter BSM 382 carries out two
measurements: Firstly, the blood oxygen
saturation and secondly, the pulse rate in the
finger tip. Additionally, the pulse intensity is
displayed as bar graph or wave diagram
(plethysmograph). For this purpose, the device is
clamped to a finger. Using infrared light, the
device can carry out measurements and assess
the colour deviation for different levels of blood
oxygen saturation to determine the current values.
Potential sources of errors due to external
influences include external infrared radiation, bad
circulation in the fingers and artificial or painted
finger nails.

Levels of blood oxygen saturation that are too
high may be caused by particularly quick and
deep breathing. The level may increase up to 100
per cent. However, this substantially reduces the
carbon dioxide content in the blood potentially
influencing the blood pH value balance. Breathing
air with an increased oxygen content (e.g. during
oxygen therapy) may also lead to increased levels.
Pulmonary emphysema
Asthma
Reduced respiration
Circulatory disturbance
Heart defect
Blood pH value disturbance
Low oxygen content in the ambient air
(e.g. in high-altitude mountains)
Increased oxygen consumption, e.g. through
physical exercise
For healthy people, a normal blood oxygen
saturation level of between 92 - 98 % is
measured. Diseases or conditions leading to blood
oxygen saturation levels that are too low
include:

The measurement of the arterial oxygen saturation
level using the Pulse Oximeter BSM 382 is
uncomplicated, non-invasive (no blood sample
needs to be taken) and can be carried out almost
everywhere at any time due to the small size and
low weight of the device. Another advantage is
that pulse rate and pulse intensity are
simultaneously determined and displayed. The
Pulse Oximeter BSM 382 can be extremely useful,
particularly for activities that may lead to
deterioration in arterial blood oxygen saturation
(mountain climbing, aviation, hang gliding,
paragliding, endurance sport, etc.) but also for
private checks and during sports and leisure
activities of any kind.
4.2 Advantages of non-invasive
pulse oximetry
Pulse oximetry enables non-invasive
measurements of arterial oxygen saturation as
well as pulse rate and pulse intensity. The
measurement is carried out by two light sources
with different wavelengths (660 nm red light and
940 nm infrared light) which are shone through
the finger and hit a photo electrode on the other
side determining the potions of the light that have
passed through the finger. Depending on the blood
oxygen saturation, different portions of the light
pass through the finger. Based on these
measurements, the device determines the
saturation level.

4.3.8 Incorrect measurements may occur due to
severe hypothermia, shock and low blood
pressure as well as poisoning which
influences the oxygen binding capacity of
the haemoglobin.
For patients suffering from severe anaemia
or anaemic or toxic oxygen deficiency, the
measurements may be incorrect.
Medication such as dopamine, procaine,
lidocaine and butacaine may strongly
influence the measurement.
Strong ambient lighting from fluorescent
lamps, infrared lamps and heating devices
or direct sunlight is to be avoided.
No arterial or venous lines must be
connected to the arm of the finger which the
measurement is being carried out on and no
blood pressure cuffs may be used.
The finger used for measurement must not
be moved and the person who the
measurement is being carried out must stay
calm.
The finger must be inserted deeply enough
into the device with the finger nail pointing
upwards to the display side of the device.
There must be no dirt, nail polish or tattoos
on the finger or finger nail.
Please observe the following circumstances as
these may influence the measurement or lead to
incorrect measurements:
