Recently, we at EZ Life Healthcare shared a complete guide about the fingertip pulse oximeter and how it works. While we did cover the process in that guide, we realized it was not detailed enough, and it definitely needed some more elaboration. So, with this quick guide, we will be telling you exactly how to use a fingertip pulse oximeter the right way, step by step. And yes, we will also be sharing how to read a fingertip pulse oximeter so that you never feel confused about those numbers on the screen.
Before we jump into the steps, let us just say this: a fingertip pulse oximeter is one of the simplest and most affordable health devices you can keep at home. It clips right onto your finger and gives you two very important readings: your blood oxygen level and your pulse rate. So if you own one or are planning to get one of the top-rated fingertip pulse oximeter models available in the market, this guide is going to be very useful for you.
Step 1: Choose the Right Finger to Use Your Fingertip Pulse Oximeter On
This is actually the first and most important step when you are learning how to use a fingertip pulse oximeter. Most doctors and health experts recommend using your middle finger or your index finger of your right hand for the most accurate reading.
You should avoid using your thumb or your pinky finger because these fingers do not always give the most accurate signal to the device. Also, if you have nail polish or artificial nails on your fingers, please remove them before using the pulse fingertip oximeter because nail colour can actually block the light sensor and give you a wrong reading.
Step 2: Make Sure Your Hand is Warm and Relaxed
Cold hands are one of the most common reasons why a fingertip pulse oximeter gives an incorrect or unstable reading. If your hands are cold, just rub them together for a minute or two, or wash them with warm water before you use the device.
Also, your hand should be relaxed and still. Do not hold anything or clench your fist while taking the reading. A relaxed hand helps the pulse fingertip oximeter detect your blood flow properly and gives you a more stable and reliable result.
Step 3: Turn On the Fingertip Pulse Oximeter and Insert Your Finger
Now, open the clip of your fingertip pulse oximeter by pressing on the back of the device. Most top-rated fingertip pulse oximeter models, including the ones available at EZ Life Healthcare, turn on automatically as soon as you open the clip and insert your finger. If yours does not turn on automatically, just press the power button on the side.
Insert your finger into the device so that your fingertip is touching the inside tip of the oximeter. Your finger should be placed firmly but comfortably, not too loose and not too tight. The small light sensor inside the device will now start scanning your finger to detect your blood oxygen and pulse rate.
Step 4: Keep Your Hand Still and Wait for the Reading
Once your finger is inserted into the fingertip pulse rate oximeter, you need to stay still for at least 10 to 15 seconds. This is very important because any movement of your hand or body can cause the reading to fluctuate or show an error.
Rest your hand on a flat surface like a table or on your lap, and just breathe normally. Do not talk, walk around, or shake your hand while the device is taking the reading. The screen will stabilize once it has captured a proper signal, and that is when you will get your final reading.
Step 5: How to Read a Fingertip Pulse Oximeter Display Correctly
This is the part most people get confused about, so let us explain it in a very simple way. When you look at the screen of your fingertip pulse oximeter, you will see two main numbers displayed.
SpO2 - This is your blood oxygen saturation level, and it is shown as a percentage. A normal reading is anywhere between 95% to 100%. If your reading is below 94%, you should consult a doctor as soon as possible.
PR bpm - This is your pulse rate or heart rate, and it is measured in beats per minute. For most healthy adults, a normal resting pulse rate is between 60 and 100 bpm.
Some top-rated fingertip pulse oximeter devices also show a third reading called PI, which stands for Perfusion Index. This tells you how strong your blood flow is at your fingertip. A PI value of 1% or above is generally considered a good signal quality.
So now you know how to read a fingertip pulse oximeter and what all those numbers actually mean.
Step 6: Take Multiple Readings for Better Accuracy
One reading is sometimes not enough, and this is something most people do not know. If you want to make sure your reading is accurate, take at least two to three readings with a gap of one to two minutes between each reading.
This is especially helpful if your first reading looks too low or too high and does not match how you are feeling physically. A good quality pulse fingertip oximeter will give you consistent readings each time if used correctly. If the readings keep varying a lot, check if your finger is properly inserted and your hand is warm and still.
Step 7: Record and Monitor Your Readings Over Time
If you or someone in your family is using a fingertip pulse rate oximeter to manage a health condition like asthma, COPD, or heart disease, it is a very good habit to note down your readings every day at the same time.
You can maintain a small diary or use your phone to record the SpO2 and pulse rate values. This will help your doctor understand your health pattern better and make more informed decisions about your treatment. Most doctors actually appreciate it when patients bring their recorded readings during a visit.
Step 8: Clean and Store the Fingertip Pulse Oximeter Properly
After you are done taking your reading, gently remove your finger from the device. The device will turn off automatically in most cases. If it does not, press the power button to switch it off.
To clean it, use a soft dry cloth or a cotton pad slightly dampened with an alcohol wipe. Do not use water directly on the device, and do not immerse it in water. Store your pulse fingertip oximeter in its box or pouch in a cool and dry place, away from direct sunlight and dust. Taking care of the device will make sure it lasts longer and gives you accurate readings every time.
