Pulse Oximetry is a technique designed to measure the blood oxygen level and heart rate. Finger pulse oximeters detect changes in pulse and blood oxygen level, giving you the chance to control the situation. Just clip on the finger pulse oximeter to get the readings in a short while. It is beneficial for patients with COPD, asthma, congestive heart failure, or other health issues. Pulse oximeters provide a painless way to measure oxygen carried by the blood in the body. They are small and lightweight for added convenience. Pulse Oximetry can assist medical professionals in decision-making but cannot be used solely to diagnose the underlying causes. Pulse Oximeters also measure pulse rate. Average pulse rate measurements range from 60-80 beats per minute in adults. While exercising, heart rate may slightly increase, and blood oxygen level may drop, but it should not be less than 90%.
A finger pulse oximeter uses infra-red light to detect oxygen in the blood. The equipment is supplied with sensors that measure the gas in the blood based on how the light passes through the finger. The result is then displayed on the screen.
Pulse oximeters are used in anumber of applications throughout the medical sciences field.
Pulse oximeters are used regularly in all conditions that tend to affect oxygen saturation levels of blood. The most commonly found ones are -
Other situations which require use of pulse oximeters are -
Values of the pulse oximeters, i.e., oxygen saturation (the amount of oxygen carried by the blood compared to its maximum capacity) may vary when there is a change in the person's activity level throughout the day. To determine your average value, you must check the blood oxygen level 4 to 5 times a day and record the values along with the activities you do before checking.
A need for oxygen supplementation is indicated in patients with acute respiratory disorders like influenza or an asthma attack if the SpO2 drops below 92 percent. In patients with chronic respiratory diseases like COPD, further investigation or long-term oxygen therapy is recommended if the SpO2 drops below 92 percent.
Most pulse oximeters have a visual representation of the pulse intensity as well as a digital display of the pulse. The pulse display should be within three beats per minute of the display on the cardiac monitor. The bar pulse display or pulse waveform must cover half of the total display for an accurate reading. Differences greater than this will not reflect accurate oxygen saturation values because the probe is not detecting the arterial pulsations adequately or accurately. Some newer monitors have integrated the ECG complex with the oxygen saturation probe. In pulse oximeters representing the signal as waveforms the morphology of the waves should be looked at which will point towards the accuracy of the signal pick up by the probe.
There are no known risks or dangers of using pulse oximeters, provided they are used in the correct way intended.
Pulse Oximeters provide readings of oxygen levels in a person's blood. Most of them also have the ability to read BPM (Heart Rate). When it comes to COVID-19, it is said that most of the cases involve a dip in SpO2 (oxygen saturation) levels in patient's blood. Having a pulse oximeter can help provide early assistance in such cases. If your reading of oxygen saturation falls below 92%, it is highly recommended to contact a healthcare professional.
The Non-Medical devices tend to be cheaper than medical options and are also portable. On the other hand, medical devices are intended for heavy use and provide multiple readings than non-medical ones who offer 2-3 readings.

Finger Pulse Oximeters are tiny, pocket-size devices weighing a couple of pounds. They display SpO2 (oxygen saturation) and BPM (beats per minute) readings instantly and at the same level of accuracy as large medical devices. They can be used on a vast age range. Below are some of our top picks of Fingertip Oximeters -
Handheld Pulse Oximeters are mainly used for longer durations and continuous monitoring. Unlike finger oximeters, handheld options tend to provide extra readings and also feature alarming systems for when readings fall out of the average limits. You may choose from the below top selling options -

Top 6 Best Pulse Oximeters for Home Use in 2025
The pulse oximeter readings are easily read and offer fairly accurate oxygen levels when checked daily. Pulse oximeters are inexpensive, require little or no prescription, and are non-invasive. Most FDA-approved pulse oximeters are used by placing them on a fingertip.
What Is A Pulse Oximeter and How Does It Work?
A pulse oximeter is one of those items that should be in any healthcare toolbox, especially if the person suffers from any pulmonary disease(s) such as emphysema, asthma, chronic bronchitis, lung cancer, cystic fibrosis, pulmonary fibrosis, heart disease, or shortness-of-breath
A pulse oximeter is a small, lightweight device that monitors the amount of oxygen transmitted into the body. It also determines the pulse rate. Pulse oximeter is a convenient and painless method of keeping an eye on a person’s arterial oxygen saturation and heart rate.
Pulse oximeters provide regular observation and monitoring of the oxygen saturation of haemoglobin in arterial blood. These devices are generally used in hospitals, medical clinics, operating rooms as well as in homes for patients suffering from asthma, COPD (chronic obstructive pulmonary disease) and congestive heart failure. Individuals with serious respiratory issues should have their SpO2 (or saturation of peripheral oxygen) level checked on a regular basis.
A pulse oximeter just needs to be clipped on to your fingertip. The probe passes two types of light through the finger – infrared and red. These are transmitted from the probe through the body and into a light detector on the other side. If the haemoglobin is saturated with oxygen then it will absorb more of the infrared light and if there is less oxygen then more of the red light will be absorbed. This is converted into a digital value which is displayed on the pulse oximeter’s screen.
The number displayed on a pulse oximeter reflects the percentage of haemoglobin saturated with oxygen. Pulse reading in high 90s - from 96% SpO2 through 99% SpO2 - is considered normal. SpO2 reading of 92% or lower is considered as low blood oxygen supply. This indicates hypoxia and requires immediate attention.
