Which Pulse Oximeter Should You Choose?

Pulse oximetry has been a standard method in clinical practice for the measurement of oxygen saturation as it shortens the time required to detect hypoxemia. In choosing such a device the features and options you would require would depend on the condition and the setting to which the device will be used.

Hospitals and Clinical Practice

The most commonly employed pulse oximeter in hospitals and ambulatory settings are stationary and handheld pulse oximeters. They are the bulky ones that are located by the bedside. It consists of a typical probe (either a Y-sensor probe, or a fingertip clip) that is wired to a bulky base unit. The base unit does the calculations over the difference in light absorption between oxygenated and deoxygenated blood. They are much preferred due to their cost-effectiveness and large displays that enables the health worker to see the results clearly from a distance. A great example is the Nonin 7500FO, a powerful and reliable digital oximeter that is compatible with many types of sensors (probe), and large visualization.

Home Monitoring

If you plan to use a pulse oximeter by yourself, find a type that is easy to manipulate. You would not want to take a manual with you every time you use the device. Finger pulse oximeters are the most common types purchased for home or outdoor use because of its user-friendly interface and superior portability.

Should there be a need for remote monitoring, wireless pulse oximeters would suit you best. They come with a special capability to transmit data using Bluetooth technology and upload the information to the physician’s clinic via a central notification system.

Probes

There are probes that are only for single-use while there are also some that are reusable. A certain type of probe called a Y-sensor probe can be applied to various sites ranging from fingers, toes, palm, and soles, which can be used for pediatric and adult patients.  In some cases, pediatric patients may need a special motion-resistant feature to produce more reliable results.
