Over the last few years, pulse oximeters have become more popular. The devices were first available to consumers in the early 1980s. However, their prices were quite high, which made many people shy from buying them.
With recent improvements in technology, the medical devices have become cheaper and more accurate. Today, you will find the best pulse oximeters for under $100.
How Do Pulse Oximeters Work?
Pulse oximeters are small devices that measure the amount of oxygen sent to different parts of your body, for example, the legs, arm, heart, etc. Some pulse oximeters work like heart rate monitors in that they can also calculate the heart rate.
To use a pulse oximeter, you have to place it on a thin area of your body, usually the earlobe or fingertip. The pulse oximeter has a light emitter inside the probe that sends out two streams of light; one infrared and one red.
The hemoglobin in the blood responds differently to these lights. The pulse oximeter will calculate the amount of hemoglobin in the bloodstream at these two different light wavelengths to determine the amount of oxygen in your blood.
The amount of oxygen in the blood fluctuates from time to time depending on what a person is doing. There are also some factors that can affect how the pulse oximeter works. For example, using the oximeter on a finger with acrylic nails or nail polish can lead to inaccurate results. Hand movements, a weak pulse, and cold hands can also lead to inaccurate readings.
A healthy person’s oxygen reading should be over 97 percent. Normally, the reading should not fall below 92 percent.
You may not need to measure the amount of oxygen in your body during workouts. However, serious athletes may want to monitor their oxygen levels when undertaking strenuous exercises. Pulse oximeters are also useful to mountain climbers or hikers whose oxygen levels may decrease as they go up higher altitudes.
Nurses may also need to measure the oxygen levels of patients with certain medical conditions or those recovering from surgery or other illnesses. The devices can be used to measure the health of a person with conditions such as chronic obstructive pulmonary disease (COPD), pneumonia, asthma, lung cancer, anemia, heart failure, and heart attack. There are specific pulse oximeters for nurses that are recommended for medical use.

The Innovo Deluxe oximeter has both a Plethysmograph and Perfusion Index (PI). This pulse oximeter for doctors and nurses produces accurate measurements of your oxygen levels fast.
You can see a visual representation of your heartbeat through the Plethysmograph. Each heartbeat is depicted by a wave while the amplitude shows the amount of blood in your blood vessels. When there is a good flow of blood in your body, the waveform will be consistent.
The strength of your pulse is numerically represented through the Perfusion Index. This representation ensures that you have accurate readings. If the PI value is less than 0.2%, this shows that you have placed the pulse oximeter improperly or your hands are too cold.
The Innovo Deluxe Fingertip pulse oximeter shows your Pulse Rate as well as SpO2. The combination of the two sensors above ensures accurate readings.
