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).
2. Understand the reasons for the procedure. Pulse oximetry is used to assess oxygen saturation in the blood for a variety of reasons. It is often used in surgeries and other procedures that involve sedation (such as a bronchoscopy and to make any adjustments of supplemental oxygen.
