A finger pulse oximeter is a great way to test your blood oxygen level in an instant and for a low price. These devices measure oxygen saturation in the blood and feature a bar graph that shows the pulse in real time. The results are displayed on a bright, easy to read digital face. Finger pulse oximeters are also energy efficient, and many don’t require batteries. To ensure accuracy, use a finger pulse oximeter as directed.
The finger pulse oximeter is a noninvasive device that sends wavelengths of light through the skin to determine SpO2 and pulse rate. Typically, patients with heart conditions can use the device under the supervision of a physician. Although finger pulse oximeters can aid in decision-making, they are not a substitute for clinical assessment. For the most accurate measurements of oxygen saturation, arterial blood gas measurements should still be the gold standard.
If you are unsure about purchasing a finger pulse oximeter, the FDA has provided guidelines for use. These guidelines recommend that clinical studies include patients with varying skin pigmentation to improve the accuracy of the device. Also, the FDA recommends that at least 15% of participants in a study be darkly pigmented. This will ensure a more accurate reading than if everyone in the study is light-skinned.
