Portable Oximeters

If you have serious cardiac or respiratory conditions, like asthma or a lung condition like COPD or chronic obstructive pulmonary disease, you may need to use a pulse oximeter to monitor your oxygen levels—insufficient oxygen in your blood can be dangerous and sometimes fatal.

A fingertip pulse oximeter is a very convenient and easy to use medical device that measures the oxygen saturation in your hemoglobin, a measurement called SpO2 as well as your pulse rate. A fingertip is an ideal spot for many reasons—it is easily accessible and is a spot with excellent blood flow for better results. A finger oximeter unit will often measure less than 2” by 2” by 2” so you can use it—and take it—anywhere. The latest models feature streamlined designs, some in bright colors.

A fingertip oximeter uses both red and infrared light to detect oxygen levels in your blood non-invasively. Readings are instantly calculated and appear on the unit’s LED or LCD screen for you to see and record if needed.

Here are other features to look for:

• Strong visibility in low-light conditions
• A large backlit display with easy-to-read numbers
• A low-battery indicator to alert you when a change is needed
• An automatic shut-off to extend battery life
