Pulse oximeters measure the amount of oxygenated blood (Spo2) in your body, giving medical professionals and you an idea of how much oxygen your body is carrying to vital organs and tissues at any time.
The best fingertip pulse oximeter 2021 is perfect for home use, allowing you to monitor your vital signs, and gives you a better view of your overall health.
If you have a condition that affects your blood oxygen levels, such as sleep apnoea, chronic obstructive pulmonary disease (COPD), asthma, emphysema, heart failure, or lung cancer, amongst many other conditions, then you will definitely benefit from using a pulse oximeter.

The pulse oximeter is a small, clip-like device that normally attaches onto your finger, although it can be put on other body parts, such as an earlobe or toes.
The oximeter beams different wavelengths of light through a relatively transparent area of the skin of your finger targeting haemoglobin, a protein molecule in your blood that carries oxygen.
Depending on the level of oxygen it is carrying, the haemoglobin absorbs different amounts and wavelengths of light. The pulse oximeter reading is a percentage of the level of oxygen in your blood.
How to use a fingertip pulse oximeter
What are the symptoms of not enough oxygen in the blood ?
Hypoxemia (low oxygen in your blood) can cause hypoxia (low oxygen in your tissues) when your blood doesn’t carry enough oxygen to your tissues to meet your body’s needs. The word hypoxia is sometimes used to describe both problems.
Low blood oxygen levels can result in abnormal circulation and cause the following symptoms:
Shortness of breath
Colour changes in your skin ( can vary from blue to cherry red )
Slower heart rate
High blood pressure
Lack of co-ordination
Tips to Consider When Using a Pulse Oximeter
To ensure that optimal accuracy is reached when using your pulse oximeter, please follow the following tips:
Ensure you warm your fingers and hands before taking your measurements by rubbing your hands together. Rememberthat low blood perfusion can affect the accuracy of your readings. Your pulse oximeter measures your PR (pulse rate) and SpO2 (oxygenated blood) based on your blood flow.The pulse oximeter will not show a reading if the blood flow in your finger drops below a certain level.
Try to keep your finger or hand still when taking a reading as movement can make the oximeter reset its reading.
Avoid using the fingertip pulse oximeter over fake nails or nail polish as this may cause a false reading.The colour can absorb light emitted by the oximeter and interfere with the detection of oxygenatedhaemoglobin.
Be patient when waiting for a reading. It can usual take around 10 seconds for the display to show a reading, and in some people up to 30 seconds.
If you have a medical condition such as hypotension (low blood pressure) or atrial fibrillation (irregular heart rate), then you may get an inaccurate reading.
What is the best oxygen level ?
Pulse oximetry measures the percentage of oxygen in haemoglobin proteins, called oxygen saturation. Oxygen saturation usually indicates how much oxygen is getting to the organs.
Normal oxygen saturation levels are between 95 and 100 %. Oxygen saturation levelsbelow 90 percent are considered abnormally low and can be a clinical emergency.
How accurate are fingertip pulse oximeters ?
Most oximeters will give a reading + / – 2% what your saturation levels would be if they were obtained by an arterial blood gastest.
The oximeter can be less accurate if you have dark skin, or if your saturation levels fall below 80 %.
Other factors that may reduce the accuracy are –
• Patient movement
• Bright light on the probe
• Nail varnish or pigment on finger
• Poor perfusion
• Carbon monoxide poisoning
Which finger is best for your pulse oximeter ?
Pulse oximeter measurements taken on the index, middle and ring fingers are less prone to error readings, and appear to show the greatest accuracy of the arterial oxygen saturation.
1. Your pulse oximeter can be used before or after doing sports, but it’s not recommended to use during the process of doing sports as you need to remain still when taking measurements.
2. Do not use the device on infants or neonatal users.
3. The device is not intended for use as a course of treatment. If you are in any doubt or concerned then please contact your doctor, or designated healthcare professional.
None of the information given is intended to be a substitute for professional medical advice, diagnosis, or treatment. You should always ensure that you seek the advice of your general practitioner or other qualified health provider with any questions you may have regarding a medical condition.
