A finger pulse oximeter measures a person’s blood oxygen saturation and pulse rate. They are widely used in the medical field and are also commonly used by pilots, athletes as well as people that work or train at high altitudes. A person’s entire body can be deprived of an adequate supply of oxygen, which is known as generalized hypoxia or simply a certain region of their body, commonly know as tissue hypoxia. This is a pathological condition that must be taken seriously and monitored. It is now easy and affordable to check your own heart rate and blood-oxygen saturation levels with a finger pulse oximeter.
Otherwise normally healthy people can succumb to generalized hypoxia when they travel to high altitudes where it can cause altitude sickness with potentially fatal complications such as, high altitude cerebral edema and pulmonary edema. Divers can also experience hypoxia when using a closed-circuit re-breather controlling the amount of oxygen present in the air they breathe. A finger pulse oximeter is often used by athletes when altitude training, as they purposely attempt to develop performance adaptations at the systemic and cellular levels. In such cases, a finger pulse oximeter is vital in order to monitor blood oxygen saturation.
What are the uses of pulse oximeter
A pulse oximeter is also an invaluable tool in the field of medicine. The ease and speed at which a finger pulse oximeter can be used becomes a critical factor in emergency medical situations. They are also an excellent tool in diagnosing sleep disorders like apnea and hypopnea and are often used for people suffering from respiratory or cardiac conditions such as COPD.
Because of the simplicity of the finger pulse oximeter, it is easy for anyone needing to monitor or check his or her blood saturation level to learn how to use it in a very short time. The finger pulse oximeter has been used successfully by people suffering from a breathing condition, mountain climbers, athletes and pilots around the world. Using your finger pulse oximeter is as easy as placing it over your fingertip and touching one button. The meter then turns on instantly and a display lights up. It immediately gives you vital, real-time information on blood oxygen saturation levels as well as your heart rate. Once you have your readings and take the finger pulse oximeter off, it will automatically turn off after 6 seconds, saving the life of your battery.
How to use Pulse Oximeter
Reading your finger pulse oximeter can’t be easier as it boasts a bright LED digital display that is easily seen. Your meter comes with a lanyard cord that can be used on your wrist or neck, a protective and stylish carrying case complete with instructions and a manual as well as 2 AAA batteries.
The specialized pediatric digital finger pulse oximeter is designed for children between 33-100 lb and uses a unique oximetry sensor, which has been specifically calibrated for children. This is a critical feature as it minimizes measurements that can be inaccurate due to movement by the child. The pediatric finger pulse oximeter is constructed with a smaller opening to fit a child’s finger and even comes a with visible mark that helps children place their finger in the correct spot. Take some time now to learn about the finger pulse oximeter and find out why it is the number one choice both in the medical field and by the general public.
Different types of oximeters
There are a variety of fingertip devices on the market that will measure your blood’s oxygen level, each of which have pros and cons. These are huge and more sophisticated oximeters that are usually used in the hospitals. The usual oximeter may be hard to administer to a new born baby. A comparatively small probe is attached to a computerized unit. One of the units that is trusted by professionals around the country is the CMS 50-DL, a lightweight and inexpensive option with a variety of features including long battery life, an intuitive and easy to read display and it also comes with a neck or wrist cord and storage case.
- The readings of blood oxygen saturation levels and pulse rates are displayed on a monitor that is connected to the main instrument with the help of cables.
- The device has a probe which is put on the baby’s head in order to get a reading from the skull by the passing of light rays.
- It is clipped to the spot on one’s body that is characterized by a good blood flow (usually the earlobe or finger). There is a light emitter insides the probe.
- The most common is the portable fingertip pulse oximeter, which is often used at home.
- For its sheer size and complexity, it is not recommended for personal use.
The probe helps to get the device to the baby through the birth canal. It sends out two streams of light – infrared and red. It is relatively inexpensive, lightweight and easy to use. The wrist worn oximeter is very easy and comfortable to use. The doctor can be alerted of complications beforehand due to this device and can take the required steps faster. Opposite this emitter there’s a photodetector that receives the streams and measures them as they pass through. However, it doesn’t always provide an accurate reading for those with circulatory problems. The patient can wear it on the wrist. Pulse oximeter readings corresponding to 190 blood samples were analyzed. The different types of oximetry tests are found in intensive care units of hospitals and in medical facilities such as overnight test centers for sleep apnea.
Also, it is designed for spot checks, instead of continuous monitoring so there are also several other options available. These are portable oximeters. All oximeters detected hypoxia but motion and low perfusion degraded performance. Equipment for testing blood-oxygen levels is also available for use at a patient’s home. However, when purchasing them for home use, it is recommended that PCI compliance should be ensured for accurate readings.
Three of four oximeters (Masimo, Nellcor, and Philips) had root mean square error greater than 3% for SaO2 70 to 100% during any motion, compared to a root mean square error of 1.8% for the stationary control. Variations in oxygen levels in the blood can be an indication of many different health conditions, therefore oximetry tests are often followed by other tests for diagnostic purposes. The patient can opt for a wrist oximeter that has features like long battery life (in case of portable oximeters), enhanced memory and which is also Bluetooth enabled. A low perfusion index increased error.
Choosing the right pulse oximeters in UK
One of the most sought after items in the market right now, the BCI model collects information and returns highly accurate readings on Sp02, pulse strength, and pulse rate measurements. It doesn’t matter how old or young you are, this piece of equipment will work on anyone!
However, the BCI portable pulse oximeter isn’t the only product of its kind. There are plenty competitors out there, some of them more affordable than others. In fact, if you are looking for a discount model, you may be better served looking somewhere other than the BCI product (with that said, you certainly get what you pay for with BCI. The value is quite worth the price tag).
So, what kind of features do most of these digital finger pulse readers have in common? Well, this is a common question we get, considering you have so many choices out there that are available to you. There is the Pulseox 5000, the Onyx, and the ever popular Respironics 950 model, just to name a few. But don’t worry—we’ll try to slow your head from spinning too much (in other words, you’ve come to the right place).
Most products will display your pulse strength on a small LED screen (or, in some cases, a different type of screen). This way, you won’t have to “cup” your hands around the screen to see your readings as the screens are typically easily readable in light or dark settings. The size of the screen varies from brand to brand, model to model. However, if you have severely impaired eyesight, it is suggested that you shoot for purchasing a model with a bigger screen.
These handy devices are typically charged by one or two “AAA” batteries, and require very minimal power to operate. So, if you’re the extra-conscientious type who likes to check their readings every hour or so, you don’t need to worry about planning on weekly trips to the grocery store to pick up a new batch of batteries.
These devices are also very lightweight. Some only weigh a few ounces, with the BCI Digit coming in at 3 ounces itself. Their size and portability make it easy for the person who is “on-the-go” a lot, so as long as you have a pocket, or even a small purse, you’ll be good to go. Occasionally, a maker will ship a belt-clip with their product that can attach to the back of their product, making traveling with these handy tools even more convenient
Like the BCI mentioned previously, most finger pulse oximeters can be used by anyone of any age, from pediatric use all the way on up to senior use. These machines perform equally as well across all age ranges without any test having proven otherwise.
If you want to buy finger pulse oximeter devices, you have come to the right place. We hope to do the best we can at providing all of the information there is to be had on the topic, and hopefully lead you to some great products that will serve you well in your future.
