Thank you for purchasing the Braun Pulse oximeter, BPX800. 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 (BPX800) is a non-sterile, reusable device intended for spot checking or intermittent determination of 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 intended for adults 21 year of age or older, in a home-use environment (such as a home setting or places of business). The pulse oximeter displays the percent oxygen saturation in arterial blood (SpO2), pulse rate, as well as the pulse amplitude using a vertical bar graph.

WARNINGS AND PRECAUTIONS

• Please read the manual carefully before use.

• The Pulse oximeter isn’t suitable for continuous monitoring.

• 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.

• DO NOT use on the same finger continuously for over 2 hours.

• The Pulse oximeter is not appropriate for the constant monitoring of the user. Prolonged and continuous monitoring may increase the potential of unexpected changes of dermal conditions. A feeling of discomfort or pain may occur if using the device continuously, especially for those users who experience poor perfusion or dermal abrasions.

• 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).
  • 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.
  • Venous pulsations.
  • Hypotension, severe vasoconstriction, severe anemia, or hypothermia.

• DO NOT modify this equipment without the authorization of the manufacturer.

Fingertip pulse oximetry

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 Malfunction caused by anesthesia, trauma resulting from major surgery or medical examination, or other diseases due to virus or bacteria can also cause a reduction in oxygen hemoglobin saturation in arterial blood which can be detected by the pulse oximeter through a low SpO2 reading. This can result in symptoms such as depression, vomiting, and asthenia in patients.

The fingertip Pulse oximeter is a compact, low-power consumption, portable device. When the index finger is inserted into the fingertip photoelectric sensor, the display screen of the Braun Pulse oximeter will show the measured value of SpO2 and pulse rate as well as a vertical bar graph showing the pulse amplitude.

Measurement principle

Pulse oximetry is based on the difference in the selective absorption of red light by oxygenated blood or oxyhemoglobin (HbO2, which is bright red) as compared to deoxyhemoglobin (Hb, which is dull red) or de-oxygenated blood. This selective absorption is based
on the Beer Lambert Law. A red (660nm) and infrared LED (940nm) on the top portion of the prospective clamp finger-type sensor emits light at these two frequencies. The red light transmitted through the finger is selectively absorbed by the oxygenated arterial blood and the remaining light is detected by a photodetector on the lower portion of the clamp finger. The infrared light then passes through the finger without any selective absorption and is detected by the photodetector on the lower side of the clamp. The transmitted light captured by the photodetector is converted into a voltage or current signal and then passed through signal conditioning and filtering circuits using a microprocessor. SpO2 is then derived by analyzing the changes in the amplitude of these pulsatile signals derived from the photodetector and calibrating them using pulse scanning and recording technology. The pulse rate is then derived from these associated waveforms.
