These devices are generally used in hospitals, medical clinics, operating rooms as well as in homes for patients suffering from asthma, COPD (chronic obstructive pulmonary disease) and congestive heart failure. Individuals with serious respiratory issues should have their SpO2 (or saturation of peripheral oxygen) level checked on a regular basis.</p
