What is a Pulse Oximeter?

pulse oximeter is a small, lightweight digital device used to monitor your blood oxygen level. Our heart pumps oxygen rich-blood into arteries that carry the oxygenated blood to all parts of the body, including the extremities. To measure the oxygen level in your blood or the oxygen saturation level (SpO2) you can administer a test at your home using a pulse oximeter. Moreover, by using a pulse oximeter, the test is painless and noninvasive.

There are no needles and no pain involved in oximetry measurement.

It comes with a fingertip chamber or a probe sensor, finger ring sensor, or wearable on the wrist.  You can put the probe sensor on your finger or toe.  The pulse oximeter (ox) displays the measured amount shown on the screen reflects the saturation of your red blood cells with oxygen.

Pulse oximeter uses-Why do you need a pulse oximeter?

Pulse oximeter uses are very crucial. A pulse oximeter is designed to measure SpO2, and your SpO2 measurement refers to the oxygen saturation level or the amount of oxygen in your blood. The SpO2 reading 95% or above indicates that your oxygen level is normal. If your SpO2 reads below 92%; then, it is an indication that the oxygen level in your blood is poor, and you must consult to your doctor or a hematologist.

A pulse oximeter can even detect the small changes in your SpO2. It is commonly used to observe sleep apnea, pulse rate, lung medication effect, ventilator condition; also, SpO2 during exercise, aviation, and mount climbing.

If you are having a lung disease, it is significantly important to check your SpO2 level regularly or multiple times in a day. Most people are advised to maintain at least 89% of SpO2, otherwise, it can lead to cyanosis or death of their tissues i.e. infarction. For most people a pulse ox is an essential tool to measure their SpO2 frequently.    

A pulse oximeter also measures your pulse rate i.e. beats per minute. An adult person’s heart-beat range from 60 to 100. If your pulse rate is less than 60 BPM it is called bradycardia, and if your pulse rate is above 100 BPM it refers to tachycardia; under both of these circumstances you must visit a cardiologist.

Some pulse oximeter can also read perfusion index (PI) i.e. it can measure your pulse strength. 

To get an accurate understanding of your SpO2, pulse rate, and pulse strength within a few seconds at anywhere, you should take a pulse oximeter in your home for your personal usage.   

Which finger is best for pulse oximeter

The highest average SpO2 value was measured from the right middle finger (98.2 % ± 1.2) and it was statistically significant when compared with the right little finger and left middle finger. The second-highest average SpO2 value was measured from the right thumb and it was statistically significant only when compared with the left middle finger (the finger with the lowest average SpO2 value) (p < 0.05). SpO2 measurement from the fingers of both hands with the pulse oximetry, the right middle finger, and right thumb have a statistically significantly higher value when compared with the left middle finger in right-hand dominant volunteers. We assume that the right middle finger and right thumb have the most accurate value that reflects the arterial oxygen saturation. Source

Pulse oximetry readings can be affected by

If you are wearing dark fingernail polish and long artificial nails with artwork or if your fingers are not clean, the pulse oximeter readings will not show and may not work properly. Pulse oximetry readings can be affected by
-External Interference.
– Fingernail Polish and Pressed on Nails.
-Skin Pigmentation.
-Intravenous Dyes

False low pulse oximetry reading

Can pulse oximeter give false readings? Pulse oximeters can give a falsely high reading in the presence of carbon monoxide. Causes of false high or low spo2 readings can be happened the presence of methemoglobin (1) anemia combined with hypotension (2,3) motion (4), dark skin pigmentation including certain skin dyes (5), blue or green fingernail polish (6), and severe tricuspid regurgitation (7).

Buying Guide for Pulse Oximeter

When you are purchasing a pulse oximeter you need to take into account a few things: its accuracy, portability, display quality, affordability, fingertip sensor and so-forth.

  • A pulse oximeter must measure your SpO2 accurately with a real accuracy of +/- 2%, and it must also provide pulse rate accuracy within +/-5 BPM within 30-240 beat per minute, and the figures must show in real-time.
  • The device must show SpO2, pulse rate, pulse strength in real-time, and low battery indicator must be visible.
  • It must come with a vibration alarm system so that if your SpO2 or BPM don’t meet your pre-set stander the vibration alarm must notify you about it. 
  • It should be portable and lightweight so that you can carry it and check your SpO2 and BPM with this device at anywhere.
  • The fingertip must not contain latex material and must be hypoallergenic.
  • Don’t choose a pulse oximeter for your child which is meant for adult.
  •  Display must be either OLED, LED or LCD. And it must offer 2, 4 or 6 display directions.
  • Some pulse oximeters come with APP option, and they allow you to export data in your computer so that you can study them and share them with doctor.
  • Consider the battery life and memory of a pulse ox meter. Try to choose those have long-lasting battery and are built-in memory.
  • You also need to consider for which purpose you are aiming to buy a pulse oximeter because some are meant for sports, aviation, or normal usage. Different pulse oximeter serves different purpose e.g. if a pulse oximeter is designed for home use, it cannot be used for professional healthcare purposes.
  • While you are shopping a pulse oximeter, check whether it fits to your fingers, if it doesn’t fit properly it won’t show you the accurate SpO2 and also, it may go off from your finger during regular activities. Concerning children, you must frequently check whether their new pulse oximeter creates any tenderness on their fingers.
  • To check whether a pulse ox is accurately measuring your pulse rate, you can manually check your pulse rate; then, match your manual measurement with the pulse ox.
  • As per WHO, if you want to check whether your pulse oximeter is working; then, put the probe on your own finger to see whether it is working.

How to read a pulse oximeter?

The measurement that is administered to get an insight of the oxygen level in your blood is called SpO2 i.e. oxygen saturation level. A pulse ox can be used to conduct this measurement; however, most pulse ox give a +/- 2% reading i.e. pulse oximeter accuracy range reading may be 2% higher or 2% lower than your actual SpO2 level. For example, if a pulse ox reads your SpO2 is 92% i.e. your actual SpO2 may be either 90% or 94%. Therefore, this measurement is not 100% accurate, but it is easy to administer this test and doctors often rely on this test.

If your pulse oximeter gives a reading of your SpO2 level between 95% and 100%; then, it means your SpO2 is normal. However, this rule doesn’t apply to the COPD patients and respiratory. If your pulse ox shows your SpO2 is 95% it means your blood contains 95% oxygenated blood and 5% deoxygenated blood.

However, it is difficult for COPD patients and respiratory patients to maintain 95% SpO2 level; therefore, their doctors prescribe them a certain SpO2 level must be maintained.

It is obvious that your SpO2 level may change throughout the day because your everyday activities may include low-energy and high-energy activities.

If your SpO2 level falls below 95%, it is an indication that you are having a hypoxemia condition, and if the condition is severe, you can have a cyanosis i.e. your skin and mucous membranes will become bluish or discolor.

If you have a chronic lung disease; then, it is significant for you to be aware of what is the normal SpO2 for you; consultant with your doctor in this regard.

How does a pulse oximeter work – How a pulse oximeter works?

When you put the fingertip chamber or probe on your finger, ear lobe or toe; a beam light sensor goes through your skin and blood; then, your blood absorbs a certain amount of beam light, and the other side of the probe detects it. The amount of beam light absorption indicates whether your blood is oxygenated or deoxygenated. Basically, this device measures SpO2 by calculating the changes of light absorption in your blood. as we discussed how does a pulse oximeter work.

The probe must be very well positioned on your finger to get an accurate reading. If the probe is very tightly fitted, it will constrict your blood circulation or if it is too lose it will fail to measure your SpO2 correctly.  Pediatric pulse oximeters are made for infants (less than one-year-old). An adult probe can be put on a child’s big toe or thumb as long as it gives a good signal. Some pulse oximeters offer an ear probe that can be used on the ear lobe.

Note that a few situations can prevent a pulse oximeter to measure your SpO2 accurately: wearing nail polish or any color pigment on the finger, bright light or sunlight, finger movement, poor blood perfusion.

To read SpO2 by an oximeter, there must be a good flow of blood through your finger. Sometimes blood flow may be interrupted because of peripheral vasoconstriction (PV). PV is commonly happened due to cold, poor blood circulation, or hypovolemia.

If a patient has inhaled a considerable amount of smoke; then, a significant amount of carbon monoxide (CO) can be found in his hemoglobin. Oximeters often fail to detect CO, as a result, they read SpO2 inaccurately.

Which finger is best for a pulse oximeter?

Putting probe on the middle finger is the best way to measure SpO2 because it is believed that middle finger contains the higher perfusion. Besides, index finger or middle finger is commonly used in clinical practice to measure SpO2 and pulse rate. To receive the accuracy, the finger must fit into your finger, and if the toe or finger is big compared to the probe; then, it will fail to measure your SpO2 accurately.

What Are the Risks of Pulse Oximetry?

Experiencing any harm using a pulse ox is very unprecedented. Even doctors often administer SpO2 test using a pulse ox, and they also consider any medical-grade SpO2 report released by a pulse ox.

However, if you are using a poor quality pulse ox; then, it may involve risk factors because if it shows an inaccurate result, your doctor won’t be able to carry out your treatment properly.

Frequently Asked Questions

How accurate are home pulse oximeters?

Home pulse oximeters are almost accurate. Most pulse ox give a +/- 2% reading i.e. the reading may be 2% higher or 2% lower than your actual SpO2 level. Simply, Pulse oximeter accuracy can give a reading 2% over or 2% under what your saturation would be. if your oxygen saturation reads 92% on the pulse oximeter, it may be anywhere from 90 to 94%.

How do I choose a pulse oximeter?

When you are choosing a pulse oximeter, a few important features of a pulse ox must be taken into account: its real-time readings, accuracy, design, features, vibration alarm, portability, memory, battery life, compatibility, safety, fingertip chamber, ring sensor, display, age variation.

What is a good heart rate and oxygen level?
