Indications For Use; Warnings And Precautions; General Description - Braun Pulse Oximeter 1 Bedienungsanleitung

Thank you for purchasing the Braun Pulse oximeter, YK-81CEU. This
pulse oximeter is a high-quality product tested in accordance with
international ISO safety and performance standards. This device
uses red and infrared light at set wavelengths along with a
photodetector to measure oxygen saturation in blood and the
associated pulse rate.
The Braun Pulse oximeter is intended to be used by consumers in a
home-use setting (such as home setting or places of business).
Please read these instructions carefully before using this product
and keep the instructions and the pulse oximeter in a safe place.

Indications for use

The Braun Pulse oximeter (YK-81CEU) is a non-sterile, reusable device
intended for spot checking or intermittent determination of functional
oxygen saturation in arterial blood, as well as the associated pulse rate
by using the tip of the finger as the measurement site. The device is
only intended for people 18 years of age or older, in a home-use
environment (such as a home setting or places of business).
The Pulse oximeter displays the %SpO2, pulse rate, as well as the
pulse amplitude using a vertical bar graph.
The Pulse oximeter should only be used by people 18 years of age or
older.

Warnings and precautions

Please read the manual carefully before use.
Device isn't suitable for continuous monitoring.
The measurement results of Braun Pulse oximeter cannot replace
the doctor's diagnosis, please follow the guidance of a professional
doctor.
Pulse oximeters are sensitive to motion. Keep hands still while
taking a reading.
Pulse oximeters require sufficient blood flow to obtain proper
readings. Poor blood circulation can result in inaccurate readings. If
your hands are cold or if you have poor circulation, warm your hands
by rubbing them together or use another warming method before
attempting to obtain a reading. A tourniquet, blood pressure cuff,
other devices or clothing that cause blood flow restrictions may also
result in inaccurate readings.
Fingernail polish or acrylic nails obstruct the light transmission
through the fingertip and may also result in inaccurate readings.
Your finger must be clean for a proper reading.
The Pulse oximeter should be clean in order to get a proper reading.
Please ensure the finger clip area is cleaned, following the cleaning
instruction in the manual.
If a reading is difficult to obtain, switch to another finger or to the
other hand. The index or middle finger is recommended for taking
measurements.

There are a number of other conditions which may lead to an
inaccurate reading; including but not limited to, recent medical tests
that included an injection of dyes, use of arterial catheters, a weak
pulse, low levels of hemoglobin in the blood, low perfusion (the
quality of your pulse), elevated levels of dysfunctional hemoglobin,
the strength and type of light that you are in while using the pulse
oximeter, and the existence of cell phones, radios, and fixed
transmitters within certain ranges of the pulse oximeter during use.
This device does not provide a low SpO2 alarm.
DO NOT use on the same finger continuously for over 2 hours.
The device is not appropriate for the constant monitoring of the
user. Prolonged and continuous monitoring may increase the
potential of unexpected changes of dermal conditions such as
putrescence, etc. A feeling of discomfort or pain may occur if using
the device continuously, especially for those users who experience
poor perfusion or immature dermographia by light collimation.
In addition to the items described in the Warnings and precautions
section, inaccurate measurements may be caused by factors
including but not limited to:
• Immersing the device in liquid.
• Significant levels of dysfunctional hemoglobin (such as
carboxyhemoglobin or methemoglobin).
• Intravascular dyes such as indocyanine green or methylene blue.
• Measurements may be adversely affected in the presence of
high ambient light such as direct sunlight. In bright light
conditions, cover the sensor area if necessary.
• Excessive user movement.
• High-frequency electrosurgical interference and defibrillators.
• Venous pulsations.
• Hypotension, severe vasoconstriction, severe anemia, or
hypothermia.
DO NOT modify this equipment without the authorization of the
manufacturer.

General description

Oxygen mixes with blood in the lungs and is transported in blood
mainly by hemoglobin. Chemically the oxygen molecule combines
loosely and reversibly with the heme portion of the hemoglobin.
The amount of oxygen that combines with the hemoglobin is
determined by the partial pressure of oxygen. The amount of
oxygen in blood, expressed as a percentage of hemoglobin
saturation is a measure of oxygen (SaO2) in the artery and is
estimated by a pulse oximeter as an SpO2 reading.
The amount of oxygen in blood (as measured by the pulse oximeter
SpO2 reading) is a very important physiological parameter in
respiratory and circulatory systems. Many respiratory diseases
reduce the oxygen-hemoglobin saturation in human blood.
Moreover, factors such as Automatic Organic Regulation
