Best Pulse Oximeters for Home Use in India Buying Guide & Tips:
Some of the factors which you need to check while purchasing a Pulse Oximeter are as follows:
1. Accurate Readings:
This is the most important factor that a pulse oximeter should have. The devices show results which are ±2% of the actual oxygen saturation level in blood. Getting a good brand product will always have better accuracy than any random brand.
2. Size of Your Finger:
This device needs to be fitted in the finger, so check if it will fit your finger so that the correct reading can be generated. In the latest models, there is an adjustable spring system by which you can adjust the device as per your finger size. Hence it can be used perfectly for persons of any age.
For kids, make sure to select specific models meant for them as the sensors in those models are correctly calibrated to complete the job in the right way.
3. Size of the Display:
A pulse oximeter is a small device so it should have a display of optimum size so that you can see the readings. You should opt for one which displays large numbers for clear visibility.
4. Bright Display:
A display with a backlit feature helps in visibility in low light conditions. Various color options are available in this case. Also, a display with multiple viewing angles is better to avoid strain on the eyes.
5. Alerts for Warning:
There can be alerts for various factors for convenience of usage. A sound is generated in case of irregular heartbeats such as arrhythmia or other similar issues. Similarly, low SpO2 levels also come with a beep or buzz sound so that those with blurred vision can easily know the abnormal levels. Another alert needed is for low battery warning so that you can recharge it or replace it at the right time to ensure continuity of usage.
6. Time for Response:
Generally, the pulse oximeters take about 10-30 seconds for displaying accurate readings. Lesser the response time, the better it is.
7. Durable:
The device should be durable and waterproof or resistant to humidity to avoid chances of damage. A good device will last longer and continue showing correct results even after using it for a longer time. If you go for cheaper devices, they will pose a life risk as they do not show accurate results after using them a few times. You can find some devices with removable silicon cover for extra protection.
8. Longevity of Battery:
People using the device regularly should look for this factor to ensure continuity of operation. Otherwise, keep a spare battery that can be used in case the battery exhausts.
It is always better to opt for a model that uses Lithium-ion batteries or rechargeable ones even if they are expensive because you won’t have to face the hassle of changing the batteries frequently.
9. Automatically Activation:
This feature turns on the pulse oximeter when a finger is placed in it. It is useful while checking the pulse of spO2 levels.
10. Convenient Operation:
The device should be easy to use such that elderly people without a lot of technical knowledge can also use it easily on their own. Generally, they can be used easily just by clipping the device on the finger and clicking the switch on the button to check the results.
11. Easy to Carry Anywhere:
Since a pulse oximeter is used for measuring vital parameters, it should be portable so that carrying it while traveling will be easy. While keeping these in the pocket, there are chances of accidentally turning them on, so go for models which can be hung around the neck or have a carrying case to avoid this.
12. Check User Reviews:
It is a good practice to check the popularity of the device by going through the experience of the users to understand its characteristics and then decide if it is the best one for you.
13. Expense:
The general cost of oximeters is 2000-5000 on the basis of features provided with it, so based on your budget you can opt for a model.
14. Warranty Period:
The branded devices often come with a good warranty period so that in case of any issue, you don’t have to spend the whole amount from your pocket. Also check for a return policy so that if you receive a faulty product, that can be returned.
15. Other features:
i. Battery Saving Mode:
This is the auto shut-off feature that comes into play when the device is not used for some time and hence enhancing the battery life.
ii. Saving the History:
If you want to check your previous readings and compare them with the current readings to track the performance of your body, then this feature is quite useful.
Types of Pulse Oximeters:
The Various Types of Pulse Oximeters are:
1. The portable finger pulse oximeter:
These are small and portable devices that can be clipped onto the finger and show results in a few seconds. You can check your blood oxygen level easily at home using this.
2. Handheld Pulse Oximeter:
They are somewhat sophisticated but show more accurate results than the portable finger pulse oximeter. It has a probe and a handheld display, both connected using a cable. The patient’s index finger is attached to the probe after which the oxygen level is shown on the skin.
It is suitable for continuous monitoring of oxygen saturation levels in the blood. They are often found in an ambulance, emergency medical services, and medical institutes.
3. Tabletop Pulse Oximeter:
They have a bigger size compared to the handheld oximeters. It also has a probe and a display screen, both connected using a cable.
Some models of tabletop oximeters also come with audio and visual alarms that help alert the people around whenever there is a fall in pulse rate or blood oxygen levels. In some of these models can store old data and comes with a visual or audio alarm in case of abnormal oxygen levels
4. Pulse Oximeter that will be Worn on Wrist:
They are used for continuously monitoring blood oxygen levels and are particularly useful when you are sleeping. The probes are attached to the finger and the reading comes on the screen which is worn on the writs. A short cable connects the display and the probe. Some can even store older data, allow Bluetooth connectivity, and support data transfer via USB.
5. Pulse Oximeters for Infants:
They are meant for kids under 4 years old and can easily fit their small fingers to show correct results. You can’t use the bigger ones for them because of the improper fitting. Certain devices come with an alarm that rings when the blood oxygen is lower than the normal level. Some come with anti-motion features to provide accurate results even if the kid accidentally moves his hands during the measurement.
How do Pulse Oximeter Devices Work?
Pulse oximeters are used for measuring the oxygen quantity in the blood hemoglobin, which is referred to as SpO2. Light is used for monitoring this parameter. Red light which has a wavelength of 650 nm and Infrared which has 950 nm wavelength are used for this purpose. Oxyhaemoglobin absorbs more infrared light compared to the red light but deoxyhemoglobin absorbs red light more than infrared light.
Then the ratio of red light absorbed is compared to that of the infrared light. Depending on the amount of these lights absorbed, the oxygen saturation level in the blood is determined.
Advantages of Using a Pulse Oximeter:
Here are the Merits of using a Pulse Oximeter:
1. While Playing Sports at High Altitude:
Oxygen levels in blood drop while playing games at high altitudes so it is important to measure it to avoid the levels from falling below the standard levels and take proper precautions.
2. Managing Chronic Obstructive Pulmonary Disease(COPD):
COPD needs consistent monitoring of blood oxygen levels so that whenever it reaches very low immediate medication can be administered.
3. Asthama Patients Need It:
Asthma patients face the issue of getting their airways restricted. A quick alert regarding the blood oxygen level can help you become aware of handling the situation by taking proper steps. People suffering from sleep apnea or that administered anesthesia also need this for safety.
Warnings in Certain Situations:
1. People with Darker Skin Complexion:
The Spo2 levels will be overestimated in case you are using the oximeter on painted fingers or nails. AS per some experts, the device doesn’t work in case of people having jaundice or darker skin complexion, i.e it shows incorrect results. To resolve this issue, the sensor can be placed on the wrist or earlobe with lower pigmentation.
2. Emergency Cases:
Incorrect results are shown by the device when the SPo2 levels in the blood fall below 80% when you need immediate medical attention for safety.
3. Carboxyhemoglobin:
Verification of the Pulse Oximeter Readings:
This can be done through blood gas analysis whenever the carbon dioxide levels shoot up. The device can’t differentiate between hemoglobin cells that carry oxygen and those which carry carbon dioxide. Thus, it is risky to depend completely on the readings of oximeters in such cases.
We have covered all aspects of pulse oximeters so that you can easily make the purchasing decision to get the best one for your family’s safety.
Frequently Asked Questions (FAQs)
Q. Can an Oximeter Help Detect COVID-19 at Home?
