Helpful to monitor blood oxygen levels for children and infants. Few come up with alarm to alert if the oxygen level goes below the safe range.

Kids keep moving their hands to get the accurate readings in this situation few oximeters have anti motion feature.

How Pulse Oximetry Devices Work

Pulse oximeters’ work is simple, as the device is first clipped on fingers, toes or earlobes, which are quite transparent in our body.

Then, probe side of it emits a light, containing two unique wavelengths (650nm and 805nm) and the other side contains a light sensor. The haemoglobin in our blood and oxygen molecules that aren’t certain of being attached to them absorbs light.

The sensors can discriminate about how many cells of haemoglobin in the blood is passing through artery to the attached oximeter and how many of cells oxygen molecules is attached which is called “SpO2” or peripheral capillary oxygen saturation.

How to Use a Pulse Oximeter Properly

Oximeter is easy to use. Clip the device to your fingertip or earlobe, for infants you can also attach the clip over wrist or top and bottom of the foot. To take readings then turn on the device.

There are list of variables below that needs to be avoided to get best reading:

  • Do not move during testing, body movement including shivering, sneezing can affect the right reading.
  • Use an earlobe when your nails are painted as painted fingers and toenails can affect proper readings.
  • Take reading in rooms with normal or low light, as the bright sun light or overhead light can affect reading.
  • When exposed to water the sensitive electron components inside the oximeter break. For cleaning purpose use damp cloth or alcohol swab.

Benefits of Using a Pulse Oximeter:

  • High Altitude Sports:

Before it cause a serious problem, a pulse oximeter alert you to oxygen deprivation problem. The activity or sports like mountain climbing, skydiving, hang gliding that put the person in high altitude saturation can help you from using oximeter to determine arterial blood oxygen levels.

  • For COPD Management:

The people who suffer from COPD all times Oximeter should be carried along with them. The body can no longer repair when the cells of the lungs become damaged due to chronic obstructive pulmonary disease.

To determine of the lungs are delivering enough oxygen there is a need to use the medication, lifestyle management and monitoring blood oxygen levels.

It alerts the patient when rescue medication and/or oxygen therapy needed.

  • For Asthma Patient Care:

Before an attack occur a pulse oximeter will alert the asthma patient when their airways are getting restricted and it alert them to use rescue inhaler.

  • For people who suffer from sleep apnea and severe snoring it monitors the saturation in blood.
  • If the oxygen level in blood of an infant or any patient in hospital gets low it warns the hospital staff.
  • For patients in anesthesia, it measures the saturation level.
  • If the reading is beyond limits it notifies you.


For people with dark skin:

As mentioned earlier to avoid testing on fingers those are painted and toenail because the colours may lead the device to overestimate the SPO2 level. This is a point of debate between professionals.

Testing’s has confirmed that there will be a difference between reading of oximeter and blood-gas analysis in individuals with dark skin, but some people say devices will not be affected by pigmented skin.

To help anaesthesiologists in taking care of their patients, several clinical researches have been done on individuals with dark complexion. Most of the researches has proved that even advanced pulse oximeter devices are overestimating concentration of blood-oxygen.

You can overcome this issue by holding the sensor on earlobe or on wrist directly as pigmentation is light in these areas according to several studies.

Go to the Emergency Room if:

It’s advisable to visit the hospital and seek a medical advice if your SPO2 levels are less than 80% and if you get the same results couple of times, your oxygen levels might lower than the readings. Pulse oximeters found to provide inaccurate readings when your blood-oxygen levels reach less than 80%.


If you are facing any situation which results the high CO2 levels in blood, the pulse oximeter must have verified through blood-gas analysis and provided the readings. Oximeters can’t differentiate the cells which carrying oxygen and carbon dioxide, indeed they are helpful while treating circulatory and pulmonary illness.

In these cases believing only pulse oximeter may cause serious health complications may even cause death. Consulting a doctor and understand how determine the readings and when to seek emergency medical advice.

Precautions and tips when using a pulse oximeter:

  • Toenails and fingers paint will obstruct the effective and accurate readings of a pulse oximeter. For such instances, use an earlobe for measurement.
  • Similar to toe nails, dark or any other altercation to the skin could also lead to irregular readings of the Pulse Oximeter. Your overall readings would be affected due to the poor or obstructed passage of light through the skin into the blood. If your skin tone for your finger tips is not fair, it is advised that you take the readings from the back or top of your earlobe.
  • Often than not, bright sunlight or any other on screen bright lighting could cause an effect on the accuracy of the readings. For best results, always take your SpO2 tests inside closed rooms where the light conditions are normal or dimly lit. This will give you accurate readings.
  • People who suffer from circulation related or respiration related health conditions may observe irregularities in their SpO2 readings. Hence use precautions and read the product labels for further instructions
  • When in cold or extreme weather, there would be a lot of shivering or jerking of the body. This may result in production of inaccurate readings. Hence stay calm and simple while using a pulse oximeter to test your SpO2 Levels.
  • Whenever you notice that your pulse oximeter shows SpO2 levels below 80%, there is a possibility that you may need to rush to a hospital. Sometimes, these devices may be inaccurate and unreliable. Hence be sure that you take a couple of readings at different locations and or compare it with someone healthy. This will confirm the doubts of accuracy. If it is confirmed, you would need professional medical assistance right away.
  • Anoxia due to carboxyhemoglobin: Sometimes, in cases of elevated presence of carbon dioxide levels inside the bloodstream could mean that there is a reduced or unstable levels of oxygen in the system. If you are someone who has such condition, then it is highly advised that you cross check your Pulse Oximeter readings with that of a gas-blood analysis.
  • This is so because even though helpful, no accurate pulse oximeter could tell the difference between healthy oxygen-carrying hemoglobin cells and hemoglobin cells that carry Carbon Dioxide.
  • Keep the clip and the light source clean and without any scratches at all times. Any obstruction to the light source could mean irregular readings and passage of light to the bloodstream through the skin.
