Shortly after the pandemic (COVID-19) started, there has been a sudden surge in demand for face masks, alcohol-based hand sanitizer, touchless soap and sanitizer dispenser, nebulizers, Infrared Forehead thermometers, etc. Among these, a Pulse Oximeter is also now a highly demanding product.

The pulse oximeter is a tiny and compact device, that can measure your pulse rate and oxygen level in your blood.
It is now a must-have gadget not only for clinics and hospitals but also for your home use too.

This simple yet effective tool also comes very handy in detecting the Coronavirus infection to some extent.

What is a Pulse Oximeter?

A pulse oximeter is a small clip-on device that measures the heart rate and blood oxygen level in your body. The best part is that this whole process is painless. It is commonly used on patients suffering from respiratory illnesses like asthma, lung diseases, chronic obstructive pulmonary disease (COPD), etc.

It works by attaching the device to the patient’s fingertips. And some can also be attached to their nose, ear, toe, or forehead.

Some models are battery operated and offer real-time results on a small LED present on the device. While some connect with a wire to a separate vital sign monitor. This monitor records the precise information about your heart rate, body temperature, and blood pressure using other sensors connected to your body.

Note: The normal oxygen saturation level for a healthy body is around 95-100%. The oxygen level below 95% indicates that there is a lung problem. And the level below 92% ensures that the person is in a state of hypoxia (low levels of oxygen) and needs immediate hospitalization and oxygen therapy.

Have a look at the below section to know the various benefits of pulse oximeters.

Benefits of Using a Pulse Oximeter

For patients having breathing disorders

A pulse oximeter is an ideal device for the people suffering from various serious respiratory problems like asthma, emphysema, chronic obstructive pulmonary disease (COPD), chronic obstructive airway diseases (COAD), and other respiratory conditions. It helps them to check their SpO2 Levels (Oxygen saturation level ) at regular intervals.

For people doing regular workouts

Exercise is the best way to improve physical stamina, strength, and overall fitness. But, faster exercise leads to shortness of breath. Having a pulse oximeter, you can monitor your oxygen level while exercising. This way, you can easily adjust the pace if you find that your oxygen saturation is decreasing.

For patients with serious cardiac conditions

Patients with serious cardiac conditions like hypertension, congenital heart conditions, valve disease, etc. would often experience low oxygen saturation levels. With a pulse oximeter, they can easily monitor their conditions and can use supplementary oxygen if required.

For pilots, mountain climbers, and athletes

An oximeter helps the pilots, mountain climbers, and people living in high altitudes in managing the hypoxia. Even the athletes doing high altitude training may feel a reduction in oxygen level. A pulse oximeter, therefore, helps them in determining the arterial blood oxygen levels.

For Healthcare Professionals

For any healthcare professionals working in hospitals or clinics, a pulse oximeter is a very important device. It helps them:

  • To keep an eye on the oxygen saturation level of newborn babies.
  • For any coma patients to monitor their blood oxygen level.
  • To monitor and diagnose patients with chronic respiratory diseases.
  • If anyone is suffering from anesthesia, then a pulse oximeter can monitor the oxygen level over time.
  • And very latest, it can help the doctors to keep an eye on the blood oxygen level and heart rate of Covid-19 patients.

Disadvantages of Using Pulse Oximeter

With the adjustable audio and visual alarms, it notifies you when the pulse rate or oxygen level falls.

Pediatric Pulse Oximeter

Pediatric Pulse Oximeter

The pediatric pulse oximeters are designed to check the oxygen level (SpO2 %) and heart rate from primarily the toes and/or fingers of neonates, infants, and kids under four years of age. Some advanced models also come up with anti-motion features that provide accurate measurements even while the kids keep moving their hands and legs.

How does a Pulse Oximeter help in detecting COVID-19?

Apart from fever and dry cough, COVID Pneumonia is one of the most severe symptoms found in many Coronavirus patients. This disease affects the lung’s ability to transfer oxygen. It also causes problems in breathing. And, when a person cannot inhale enough oxygen and exhale enough carbon dioxide, the pneumonia can cause death.

The normal oxygen level must be above 95%. In coronavirus patients, the oxygen level drops significantly, and they feel breathless. In some cases, with a drop in oxygen level, their kidneys, heart, brain, and all the vital organs stop working.

Therefore this smart device, the Pulse Oximeter, is used for the early detection of COVID Pneumonia. Those who found positive or suspected to have been infected with coronavirus can check their oxygen levels in the early stage. If they find a drop in oxygen levels, they can seek additional treatment, or emergency room visit immediately.

How does a Pulse Oximeter Work?

A pulse oximeter combines a sensor or probe and a monitor with a display screen. The probe is on the finger, sometimes on the toe, or earlobe. And the device detects the flow of blood through your finger, toe, or earlobe.

The pulse oximeter basically measures the light absorption in the blood. The device probe consists of two parts: light emitting diodes (LED) and a light detector. The light emitting diodes shine two types of light, a red light, and infrared light. On the other end, the light detector senses how much of each light is absorbed and how much is allowed to pass through the finger (or earlobe or toe).

The working principle includes that the oxygenated hemoglobin can absorb more of the infrared light, allowing more red light to pass through. On the other hand, deoxygenated hemoglobin absorbs more of the red light, allowing more of the infrared light to pass through.

The oximeter then calculates the wavelength’s difference between an invisible infrared light and a visible red light. And this difference determines the oxygen saturation level in your body.

The pulse oximeter provides real-time results in percentage on a small LED display present on the device.

Steps to Use a Pulse Oximeter

I. Turn on the device.
II. Clip the device on to your finger, or toe, or earlobe. If you are using your finger, make sure that the sensor is placed on the fingernail.
III. Leave the probe for ongoing monitoring of oxygen saturation level and pulse rate. Most of the oximeters will get you a reading within 10 seconds. Avoid much movement during this time.
IV. Once the monitoring is done, the readings are displayed on the screen.
V. Now check your SpO2 level and heart rate from the screen.
VI. After checking the reading, remove the oximeter and turn off the device. Some smart models also come with auto power off.

How to Use Pulse Oximeter Properly? (Some Important Tips)

  • Read the instruction manual carefully before using the device.
  • Avoid movements while using the pulse oximeter.
  • Make sure that the probe of the device is correctly positioned.
  • Never use the fingertips oximeter on painted nails as it will affect the reading accuracy. In case of an emergency, it is better to use it on the earlobe or toes.
  • Also, make sure that the patient’s hand is positioned at heart level.
  • Never use it in direct light like sunlight as it results in inaccurate readings.
  • Make sure to perform the pulse oximetry procedure in a room with adequate lighting. Though the device comes with a soft rubber that shields it from the light, it is advisable to avoid direct light shining on it.
  • Patients involved in fires or inhaled smoke may have significant amounts of Hb combined with carbon monoxide (CO). This carbon monoxide poisoning may lead to inaccurate readings.
  • The device works better with warmer hands than cold hands.

Features to look for Before Buying a Pulse Oximeter

1. Accuracy

For any healthcare device, the primary concern is that the readings it offers must be accurate. In the case of pulse oximeters, almost all the models provide an accuracy of ±2% in readings. So, you must check the error percentage of the model you are using.
Also, check the perfusion index of the oximeter. But note, the one with the lower perfusion index is more accurate and precise.

Note one more point that the accuracy of an oximeter is also affected by your motion. So, it is better to choose a model that is more tolerant to hand movements.

2. Size of probe or sensor

To get the accurate readings, it is also very much important that your finger fits properly to the probe of the oximeter. To accommodate the adults’ finger size, most of the oximeters come with the probe size ranging from 0.3 inches to 1 inch. So, you can choose accordingly that fits your finger best.

But if you are buying the pulse oximeter for children or people with small hands, choosing a pediatric pulse oximeter will be a great decision.

Even, many more advanced models also come with the adjustable spring system that can easily fit a wide number of finger sizes from kids to adults, providing accurate results.

3. Response time

No one wants to wait for a longer period to get accurate readings of their pulse rate and blood oxygen level. Thankfully, the latest and advanced models of pulse oximeters will provide accurate readings within ten seconds. Some also take a bit more. The choice depends on you.

4. Size of the Display

Considering the display size of the pulse oximeter is another most important thing. It will be great if you choose the one with a bigger LCD screen. It ensures clear visibility of the data it provides. Make sure that the screen should be bright, even with a Backlit option that allows you to see the readings clearly in both light and dark mode. Plus, the readings it provides should be large enough so that you can read it easily.

5. Auto-Rotate Screen

The model that features auto-rotate functionality on its screen is a great deal. It allows you to read the data from multiple viewing angles, making it much easier and convenient while reading the data.

6. Alarms and warning System

An alarm or warning system in a pulse oximeter is very much important. It notifies you in case you have an irregular heartbeat or low SpO2 levels. Almost all the models come with an audio-visual warning system to alert you about these irregularities. It will be more advantageous for you to choose a model with a customizable warning system, so you will never miss out any irregularities found.
