Pulse Oximeter Measurements - Why, When & How

Measuring your oxygen saturation level has become increasingly important during the COVID-19 pandemic. But why is a pulse oximeter reading so important? And how can you measure these important parameters? In this post, you’ll find the answers and some useful tips for accurate measurements with a pulse oximeter.
A normal level of oxygen is usually 95% or higher. Some people with chronic lung disease or sleep apnea can have normal levels of around 90%. The SpO2 reading on a pulse oximeter shows the percentage of oxygen in someone’s blood. If your home SpO2 reading is lower than 95%, call your health care provider.
Equipped with Bluetooth & ATC

Rossmax SB210 Fingertip Pulse Oximeter

The Rossmax SB210 Pulse Oximeter is equipped with our Artery Check Technology (ACT) and analysis the pulse and SpO2 signals. Besides the normal pulse oximeter measurements it determines the actually prevailing stiffness of the artery (Artery Condition). ACT further comprehensively classifies the arterial condition into 6 levels and presents the result by an intuitive graphical visualisation. Pulse rate, SpO2 and the artery condition are available at your fingertip!


What is oxygen saturation in blood?

SpO2, also known as oxygen saturation, is a measure of the amount of oxygen-carrying hemoglobin in the blood relative to the amount of hemoglobin not carrying oxygen. The body needs there to be a certain level of oxygen in the blood or it will not function as efficiently.
Oxygen is essential to our body. We simply need it to "nurture" our cells with energy. If your oxygen level is below 90%, then you suffer from an oxygen deficiency, also called desaturation. Possible symptoms of an oxygen deficiency are shortness of breath, confusion, fatigue and restlessness. You may also experience a headache. In some cases, hospitalization will be necessary.
If you have a symptom of shortness of breath or a known lung or heart condition, your doctor may recommend use of a pulse oximeter. The pulse oximeter, or Pulse Ox, is an electronic device that measures the saturation of oxygen carried in your red blood cells. Pulse oximeters can be attached to your fingers, forehead, nose, foot, ears or toes. The device may then be reused or disposed of. If using this in a home setting, you should ask your healthcare provider before disposing of a pulse ox device, as it can be expensive and is reusable.

Types of Pulse Oximeters

Keep track of your oxigen levels

Pulse oximeters are getting more and more functions and there are even pulse oximeter apps for smartphone devices. The pulse oximeters that you can find in our range are equipped with state-of-the-art technologies and are known for their high accuracy. Suitable for home use and for use in healthcare institutions.
The arterial pulse is detected at the digital arteries by means of a photo-plethysmographic detection technology. This means LED light is emitted from one side of the finger (the nail side) into the small arteries of the fingertips. The light will be absorbed in the tissue, - like skin layers, bone and muscles. This light is particularly absorbed once it is passing through the pulsating arteries. The arteries are changing their diameters by various degrees of filling during the pulse cycle. The Rossmax pulse oximetry technology includes a proprietary high-sophisticated pulse contour analysis of the PPG, which is enabled by a specific SW algorithm and a wide pulse filter setting. This makes a difference to other available pulse oximeters. For this reason, the ACT pulse oximetry technique is able to analyse the PPG pulse pattern and determines the characteristics of the returning wave dynamics. A narrow, high and early RTW peak can be distinguished from a wide, low and late RTW peak.

Monitoring your arterial constriction condition with Rossmax ACT-embedded Pulse Oximeter allows an early risk assessment for wide-spread clinical cardiovascular disorders.

By this non-invasive technique both, the progression as well as the actual status of pathological arterial perfusion is recognized. In addition, Rossmax offers the PARR Technology for Blood Pressure Monitors, which is a world unique stroke screening technology by distinction of pulse arrhythmia. Together with ACT Rossmax offers the total solution to monitor your health and evaluate most severe risk factors. Artery condition is associated with the potential presence of the following diseases:

  • Arteriosclerosis
  • Peripheral circulation disorder
  • A wide range of cardiovascular diseases

A pulse oximeter is easy to use and is therefore often used in hospitals and healthcare institutions.

Home use has become increasingly important since the start of the COVID-19 pandemic. Put your finger inside the meter, press the on-off button and monitor your results directly on the screen! Here we have some tips for you for an accurate pulse oximeter reading:

  • Rub your hands before measuring your oxygen level, especially if you have cold hands.
  • Do not use nail polish or artificial nails when measuring your saturation.
  • Always put your left middle finger deep enough into the pulse oximeter so that it can detect your finger.
  • Hold the oximeter at chest height for the most accurate result.



With the «Rossmax healthstyle APP» you can manage your Blood Pressure, Blood Glucose, SpO2, Weight and Temperature in only one single APP. The products will be easily connected through Bluetooth and the real-time data communication is only one click away. To share the graphs, charts or data with 3rd party provides a new experience.
