Pulse oximeters are compact and portable medical devices that measure a person's blood oxygen level by fitting onto a finger. They typically also display heart rate. In addition to being used for emergency medical treatment, oximeters are important for patients who have problems such as chronic obstructive pulmonary disease (COPD) or sleep disorders such as sleep apnea. An oximeter makes it easy for patients to monitor their blood oxygen level to avoid greater complications. Oximeters are sometimes also used to monitor training by athletes. These oximeters are simple to use and operate for many hours on battery supply. They have digital readouts that are easy to read and are small and lightweight for simple portability, so you can have them at hand when needed. Oximeters are just one example of the health and personal care products we carry, from dental care devices to blood pressure monitors, to help you live a healthier life.
