Uses of Pulse Oximeters

As we have mentioned early, these devices are used in checking the pulse rate and blood oxygen saturation. It is a small medical device that measures your blood oxygen level at a specific time. They are usually clamped to the index finger and emit a special light that can be used to measure the amount of oxygen in your blood at this time. Some also have other features, like calculating the heart rate, which is also useful during exercise.

It is of utmost importance in patients with asthma, chronic obstructive pulmonary disease, emphysema, and other respiratory diseases. In patients with severe respiratory diseases, blood oxygen content must be checked regularly. A pulse oximeter at hand is important in such conditions.

Patients with severe heart disease regularly suffer from low oxygen levels. They help you monitor your blood oxygen levels and use extra oxygen when needed. It may also indicate the change in blood volume during a pulse-taking.

In a patient with respiratory issues, a physician may recommend exercise to improve physical endurance and overall fitness. However, exercise can also cause the patient to breathe faster. Patients can use it to monitor their oxygen saturation during exercise and adjust the pace as there is decreasing oxygen saturation in the blood. Using appropriate breathing techniques during rehabilitation can increase blood oxygenation. Many low oxygen patients are able to increase these levels through simple breathing techniques.

Pilots, mountaineers, and people working at high altitudes use these products to protect themselves against cerebral hypoxia. A pulse oximeter can also help athletes achieve pulmonary endurance, especially during high altitude exercise. With the reduction in oxygen levels, there is an increase in the number of red blood cells in athletes and helps to increase stamina.

Types of Pulse Oximeters

If you look at different brands and models, you will find out that there are now many different types. Below are some of the most common ones listed.

  • Fingertip or Portable

It is the most commonly used version at home. It is very portable as it still provides pretty accurate results. This version is generally battery powered and the display is located directly on the device.

  •  Handheld

This is the type you will see in medical facilities. However, it can be bought at home and can be helpful for people with severe or chronic health conditions who require constant monitoring. It has the added benefit of providing slightly more accurate readings than the fingertip models, but the disadvantage is that it is less portable.

  • Wearable

This type is generally worn around the wrist and is usually the best for people who have serious health problems and need to constantly monitor their oxygen levels, even while asleep.

  • Pediatric 

If you want to monitor the oxygen level of an infant or child, it is important to buy a device that is designed specifically for children. Adult models do not work the same way in small children, and therefore, the readings they provide is not accurate results. For a child with extremely small fingers, you can buy a child’s pulse oximeter that you can attach to the foot or head. This can allow for much more accuracy.

How Do They Work?

how do pulse oximeters work

They measure how much hemoglobin transports oxygen in the blood (oxygen saturation). If you work in healthcare (or were patient), you’ve most likely seen one. They can be found in areas such as operating theaters, recovery, intensive care units, departments, and ambulances.

They are commonly used because they are non-invasive, cheap to buy and maintain, very compact and detects hypoxemia early.

Oxygen enters the lungs and is then into the blood. The blood transports the oxygen to different organs of the body. Oxygen is mainly transported by hemoglobin in our blood. Hemoglobin molecules (Hb) can be thought of as “cars” and “streets” as blood vessels. The oxygen molecules get into these cars and drive around the body to their destination.

The principle of pulse oximetry is based on the differential absorption properties of oxygenated and deoxygenated hemoglobin. Oxygenated hemoglobin absorbs more infrared light and emits more red light. While deoxygenated hemoglobin absorbs more red light and absorbs more infrared light.

Each device has a sensor probe that is placed either on a fingertip or the earlobe. It contains two LEDs, one emitting red light and the other emitting near-infrared light. It also has a photodetector. At each wavelength. the photodetector measures the intensity of the transmitted light. And on the basis of reading differences, the blood oxygen content is calculated.

Factors to Consider When Buying One

If you want to buy a pulse oximeter to monitor your health or use during your workout, this guide will help you choose the right model for your needs. It is always a good idea to work with your doctor when selecting one, especially if you have certain health conditions for which you are currently being treated. You and your doctor can discuss your specific health goals and how you can gain access to one at home be helpful.

With different types on the market, with different bells and whistles, it is important to understand what your specific goals are and what you will do with yours. If you have a chronic illness, you may want to look for the most durable models that will give you reliable results when used multiple times.

If you’re a fitness fan and want to improve the results of your workout, a device with a built-in heart rate monitor is probably important for you. When reviewing the various functions, notice the long-term and short-term goals in the foreground.

Different Features Available

It is important that you know the different models and features to look out for in meeting your specific needs. Here are some of the most common features that many pulse oximeters offer on the market, and who can get the most from each one.

  •  Alarms

Many pulse oximeters are equipped with alarms that sound when the oxygen level drops below a certain level. This can be very beneficial for caretakers of those with serious health conditions who need a regular pulse and oxygen saturation monitor.

  • Precision Warnings

Many models will notify you if there is an issue with the accuracy of the readings You can then make all the necessary settings to get the correct measurement

  • Battery Life

If you use your device every day or even several times a day, you should look for a brand with great battery life and durability. Alternatively, you can get a plug-in device may be best suited for everyday use.

  • Size

Most products come in a fairly normal size. The majority of probes are 0.3 to 1.0 inches in size and suitable for almost all adult fingers. When making an online purchase, you should be sure to measure your finger from the nail tip to the bottom of the finger pad just before the first joint. Use this measurement to determine the right size for you.
Buy from a trusted retailer with a good return policy.

Despite all this research and these helpful tips, you can make a purchase that does not suit your needs if you buy from a bad seller. If you make your purchase from a trusted retailer, you should be able to contact them for a return or exchange without any hassle. This is especially important when buying one online. Read the returns policy of an online retailer carefully before buying.

  • Check the accuracy before use

One last tip, make sure that the unit you choose provides accurate readings, especially if you are monitoring a serious health condition. The best way to do that is to take it to your doctor’s office. There, you can retrieve a measurement on your portable device and immediately compare it to your doctor’s display on their in-office device. However, the readings may not be the same as your doctor may use more sensitive devices. However, the two readings should be close and you know that your pulse oximeter is accurate.
