A pulse oximeter is a small, lightweight device used to monitor the amount of oxygen of your body. This non-invasive device painlessly attaches to the tip of your finger and transmits two wavelengths of light through your finger to measure the pulse rate and the amount of oxygen in your system. When the oximeter like innovo deluxe fingertip pulse oximeter completes the evaluation, the display will show the percentage of oxygen in your blood and your current pulse rate.
Pulse oximeter types
Blood saturation levels are generally monitored by a clip-on sensor device which generally is clipped onto the fingertips or earlobe, but more and more medical professionals are using wearable and handheld pulse oximeters. The handheld styles that were previously limited to hospital use are now more accessible and affordable for doctor’s offices, clinics and individuals. However, not all types of pulse oximeters are suitable for all scenarios. Check out the three most popular kinds of pulse oximeters to determine which one is best for your needs and budget.
Finger Pulse Oximeter: The finger pulse oximeter is by far the most popular style. In the form of an alligator clip, usually attached to your finger or earlobe, there is a display with SpO2 and pulse rate on top. Finger styles range from a very simple style that only reads SpO2 to a fully functional version with an LED display. These oximeters are the most affordable, compact and simple oximeters.
Wrist Pulse Oximeter: With the rise of all sorts of health and fitness bracelets, medical device manufacturers have started offering wrist pulse oximeters. These high-tech devices generally measure more than blood oxygen saturation. For example, the BodiMetrics Sleep & Fitness Monitor measures SpO2 and pulse rate to improve physical performance and sleep quality. Quite often, the wearable pulse oximeter is considered a personal or household device, but they may also be used in sleep studies, physical therapy, cardiac rehab and other scenarios where it makes more sense to wear an oximeter for a long period of time.
Handheld Pulse Oximeter: Handheld style is recommended in situations where clear digital measurement is required. The sensor is generally built-in (ideal for reading SpO2 with your thumb) and has a large LCD screen. These devices are becoming more popular in the medical industry because they offer more features than standard pulse oximeters. You can find styles that read SpO2, ECG, heart rate, blood pressure and even body temperature in one device.
How to read an oximeter?
The first number of the most oximeters is SpO2, or peripheral oxygen saturation. The SpO2 of an average healthy individual should be around 97%. Older people and people with lung disease may have low average SpO2 levels, but the level must be at least 89%.
Oxygen level measurements can fluctuate during the day, so it is recommended that people using pulse oximeters take measurements several times a day.
