A pulse oximeter is a small, lightweight monitor attached to a patient’s fingertip to measure the amount of oxygen in the body. Doctors prescribe the gadget to patients suffering from COPD (asthma and other respiratory illnesses), chronic conditions like cancers, anemia, heart problems, etc. to monitor the oxygen saturation level at home, during social activities or exercise.

Athletes like mountain climbers, bikers, scuba divers and aviation providers like pilots also use the device.

Pulse oximeters also assist doctors to decide whether the patient’s COPD is improving. Doctors prescribe different pulse oximeters to different patients depending on their oxygen saturation target.

The ideal oxygen saturation rate should be over 90% in all activities. Our discussion will review the four best pulse oximeters for home use, and their features.

It’s also user-friendly and comes 45-degree adjustable spring hinge to help fit adult-size fingers.

Though it ranks as one of the best pulse oximeters, the low-grade plastic material may be a turn-off for some users.
