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).
Preparing to Use a Pulse Oximeter. 1  1. Understand the relationship between oxygen and the blood. Oxygen is breathed into the lungs. 2  2. Understand the reasons for the procedure. Pulse oximetry is used to assess oxygen saturation in the blood for a variety of reasons. 3  3. Understand how the pulse oximeter works.
