Pulse Oximetry is a method that uses devices to measure oxygen levels in the blood. Mostly, Pulse Oximeters are big, complicate to use and are operated by electricity. Fingertip Pulse Oximeters are small devices, which clip to the finger, and can be carried around the house or outside. They are operated by 2 AAA batteries, and take continuous measurement of the SPO2 levels (oxygen-blood saturation) and heart rate. They aren’t influenced by the patient’s movement, and so, they don’t force the patient to stay in one place during the physical checkup, and they can be incorporated into athletic activity. In other words, it can help the patient live more freely.
What are Pulse Oximeters
A pulse oximeter is a noninvasive medical device that is used to measures the oxygen diffusion in a patient’s blood and pulse rates. This medical measuring instrument is very convenient and useful as it can be used with no trouble anytime and anywhere. These are abundant benefits and usages of this pulse measuring device which we will discuss later. One thing you need to make sure that you buy a good quality oximeters as not all brands make accurate and durable devices. For those living in UK can check out list of top pulse oximeters in UK.
Pulse oximeters are clipped to a semi-transparent part of a patient’s body which can be usually a finger or earlobe. A photodiode is faced with a pair of small light-emitting diodes, which has two different wavelengths. One LED is an infrared and the other is red. Absorption at the said wavelengths differs a lot between oxygenated and deoxygenated blood, thus, making it possible to calculate the ratio between the two. There are possibly four pulse oximeter types which includes fingertip, wrist, handheld and tabletop. Each of these types is made to cater to one’s medical needs.
Advantages of using pulse oximeter
The uses of pulse oximeters have become quite handy to the medical world as they are handy and convenient. Pulse oximeters’ uses include detection of under oxygenation in blood, monitoring of a patient’s tendency to have interrupted breathing during sleep, and examining pulse rates. Here are some of the advantages of pulse oximeters.
- Operation of the fingertip pulse oximeters is simple and convenient.
- The fingertip pulse oximeters is compact and ultra light (total weight is about 50g including batteries) and conveniently carried.
- Economic power consumption (two AAA batteries).
- Low voltage warning will be indicated in the visual display when battery voltage is so low.
- The fingertip pulse oximeters will automatically be powered off when out of use for longer than 8 seconds.
Fingertip pulse oximeters uses a light emitter with red and infrared LEDs that shines through a reasonably translucent site with good blood flow. Typical adult/pediatric sites are the finger, toe, pinna (top) or lobe of the ear. Infant sites are the foot or palm of the hand and the big toe or thumb. Opposite the emitter is a photo detector that receives the light that passes through the measuring site.
Using a pulse oximeter
To use pulse oximeters, you just have to attach or clip it to a part of your body—usually to a finger of an earlobe—and then wait for the reading. Its speed and simplicity made the rate of finger pulse oximeters uses very high. Portable pulse oximeters’ uses have been proven very practical, most especially for pilots, cardiac patients, athletes, and plastic surgeries. It has also been proven useful in emergency rescue medicine, like in a rescue from fire. Latest generation pulse oximeters can be attached to any part of the body and check for pulses.
How to buy the right pulse oximeters in 2018
There are many types of pulse oximeters. Each are made to cater to one’s medical needs. One of the most widely known and used type of pulse oximeters is the finger pulse oximeter. These variants of pulse oximeters are attached to the finger and from there give the blood oxygenation and pulse rate reading. These have become very handy as they are portable and efficient to use, thus, making these pulse oximeters the most common among the pulse oximeter types.
Another pulse oximeter type is one that is able to store several information regarding different patients. Because usually one oximeter is used for one patient at one time, as it is designed to monitor specific bodily functions of patients, there is now a pulse oximeter that is able to monitor several patients at the same time.
While price isn’t the most important thing to consider when buying a pulse oximeter it’s still a good idea to make sure you purchase a device that provides you with adequate readings at a reasonable price. The best pulse oximeter for home use is the one you will feel comfortable using. The FDA approved device gives you gives you fast, accurate vital signs readings. Additionally, pulse oximetry helps to ensure that hypoxic patients are treated appropriately with oxygen. The price of a pulse oximeter may vary depending on its accuracy, features, material and brand, so keep this in mind when buying a pulse oximeter.
Some come equipped to track data using apps. You can track and view your blood oxygen level readings instantly on the device LCD display and through the iHealth MyVitals app from your smartphone. The NICE sepsis guidelines highlight the importance of assessing oxygen saturations when risk stratifying patients. There are two common types of pulse oximeters: stationary and portable. We especially like that.
Ease of use
This pulse oximeter is great for athletes or anyone who wants to gain a much greater understanding of how their bodies work, both during normal recreation and high-impact sports. Additionally, pulse oximetry helps to ensure that hypoxic patients are treated appropriately with oxygen. Stationary pulse oximeters are quite bulky and widely used in medical institutions. But, if you’re not tech savvy or have no interest in that feature, many pulse oximeters come with basic functions that are simple to use. You can use your oximeter to measure your oxygen saturation level at any time, such as at home, at work or during recreation.Patients with serious respiratory problems should have their oxygen levels checked regularly and especially if they are not feeling well.
The NICE sepsis guidelines highlight the importance of assessing oxygen saturations when risk stratifying patients. They give highly accurate results, provide long-term monitoring of patients, and deliver information in a graphical format. As always, taking care of your health, should always be taken seriously. The best value category gives you well-built units with basic functions (pulse rate and blood oxygen saturation level). Any one from this category will serve you well unless you want more features or have special needs. Portable pulse oximeters, on the contrary, are the best for home use.
It’s very well-constructed and has a rugged build well-suited for travel. Add the wide array of features that bolster the precision of the readings and you have a top-notch unit you can trust. The 2-year warranty is an added bonus that ensures you’re going to receive all the help you need in case of any issues with your purchase.
