Ion irradiation is routinely used to implant impurities atoms into materials, especially semiconductors, to modify their properties. This process, usually known as ion implantation, is an important step in the manufacture of silicon integrated circuits.
Pulse oximetry is a procedure used to measure the oxygen level (or oxygen saturation) in the blood. It is considered to be a noninvasive, painless, general indicator of oxygen delivery to the peripheral tissues (such as the finger, earlobe, or nose).
âCardiopulmonary sleep disorders, essential sleep apnea, obstructive sleep apnea, upper airway resistance all require the use of pulse oximetry for diagnosis,â said Braebon CEO Richard Bonato, who added that pulse oximetry also can be used as an ongoing monitoring tool after the initial diagnosis.
