Best Pulse Oximeter

There are various models of best pulse oximeter out in the market today. If you are looking for such a device, you should pick one that is suitable to your needs as well as your budget. The size of the pulse oximeter can range from the tiny and compact ones to the large and bulky ones. The large oximeter is normally used in hospitals for Nurses, Doctors, and patients only. If you are finding one to be used at home, you will need to buy the more compact ones so it can be easily operated. There are handy pulse oximeters as well as portable fingertip pulse oximeters you can choose from. Check out various models online if you want to see your options.

You are bound to find both an affordable pulse oximeter as well as an expensive pulse oximeter. The price ranges from less than (one hundred dollars $100) up to as high as (two thousand dollars $2000). Whatever your budget may be, for sure there is the best pulse oximeter you can purchase. All you have to do is know where to search for it. Remember that price is not always the basis of the quality of the device. Just make sure that the pulse oximeter of your choice is able to give accurate readings on saturation and pulse rate. Make sure also that the device you are getting has a warranty. In case it does not work, you can return it to the store where you purchased it.

If you have a health insurance plan, there is a possibility that it can even cover the cost of purchasing the device. If you want to make sure, you can always call your insurance provider and ask about it.

If you are going to use the pulse oximeter at home, make sure you buy a simple one, that is fairly easy to use to identify the oximeter reading. Before you take it home, ask the seller to demonstrate how to operate the device so you have a good idea of how to do it yourself, and don’t forget to ask which finger is best for pulse oximeter.

If you are planning on buying the device from an online store, make sure that you read user reviews first. It gives you the correct information because you can read unbiased opinions from previous owners of the product. You can see whether they are satisfied with their purchase or not. Keep in mind that no one would share a positive review if they did not actually find anything useful with the device

Here’s a List of the Best Pulse Oximeters Under Budget

Which Finger Is Best for a Pulse Oximeter?

Pulse oximetry isn’t a new technology. It was implemented around the 1980s, but many advances have been introduced since then. Mostly, to increase the reliability of the readings.

Accuracy is often the main concern in measuring oxygen saturation, and an interesting 2015 study observed how clipping each finger affected the results.

The verdict came out that the middle finger of the right hand gives the best accuracy. The thumb of the same hand follows.

How to Read A Pulse Oximeter Reading?

You just got your new PULSE OXIMETER, now what?

Here is a quick guide to walk you through the whole process and everything you need to know!

Most pulse oximeters will give you the following information

 

  • Oxygen saturation level –  is a measure of how much oxygen your red blood cells are carrying
  • Pulse rate – is your heart rate or the number of times your heart beats in one minute.

Now how do you know if everything is normal?

 

 Best pulse oximeter readings usually range from 95 to 100 percent.

A rating under 90 percent is considering as low and indicates a requirement for supplemental oxygen.

While the pulse rate for adults over the age of 10 years, including older adults, is between 60 and 100 beats per minute (bpm)

How to read your pulse oximeter reading

This is what the normal pulse oximeter shows, although there may be some variation depending on which model you have.

 

Basically all oximeters will show you the saturation and pulse rate along with the battery indicator.

 

Above you will see the word %SP02, this is your Oxygen saturation level.

 

Below the %SPO2 you have the PR BPM which means Pulse Rate Beats Per Minute.

 

Using the photo this means that the patient has a 98% oxygen saturation level and 68 Beats per minute, which means for our example photo all the results are normal.

 

But always remember the accuracy of this device always depends on two things

 

First, make sure you buy your pulse oximeter from a reliable source

 

Second, once you have your device always use good batteries, as low battery levels can affect the results.

That’s it! You now have the knowledge to handle and read a pulse oximeter, don’t forget that if any results are lower than normal contact your emergency hotline ASAP!

What is Perfusion Index?

The perfusion index, or IP, is the ratio of pulsatile blood flow to static non-pulsatile blood flow in the patient’s peripheral tissue, such as the fingertip, toe, or earlobe. The perfusion index is an indication of the strength of the pulse at the sensor site. PI values vary from 0.02% for very weak pulse to 20% for extremely strong pulse. The perfusion rate varies according to patients, physiological conditions, and monitoring sites. Due to this variability, each patient must establish their own “normal” perfusion index for a given location and use it for monitoring purposes.

The perfusion index is normally monitored with pulse oximeters. PI is also a good indicator of the reliability of the pulse oximeter reading. For most general purpose pulse oximeters, the reading is not reliable or not available if PI is less than or equal to 0.4%. There are oximeters, like those from Masimo, designed for extremely low IP. Most people who use an oximeter at home would not need a perfusion index indicator because they are considered to be generally in good health. A perfusion index adds a lot of sensitivity to the oximeter sensor, increasing the cost of the oximeter.

 

The plethysmograph (plethysmograph), available in many pulse oximeters, is a graphical representation of the perfusion index.

 

In a hospital, the perfusion index, along with many other parameters, is used to monitor critically ill patients. Studies have shown that PI has a high correlation with capillary refill time and temperature difference from core to tip. In acute neonatal care, a low PI is an objective and accurate measure of acute disease. It is superior to the qualitative approach as foot heat.

 

The perfusion index is also used as an early warning of anesthetic failure. Studies have shown that an increase in PI is an early indicator that general or epidural anesthesia has started dilation of peripheral blood vessels, which generally occurs before the start of anesthesia. The lack of the spike would indicate the lack of anesthetic effect.

Other uses of the perfusion index can be found throughout various publications. As we learn more about IP, more clinical applications are discovered.
