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).
The correct use of pulse oximetry in measuring oxygen status. The pulse oximeter, which is used for evaluating the oxygen status of patients in a variety of clinical settings, has become an increasingly common piece of monitoring equipment. It provides continuous, non-invasive monitoring of oxygen saturation of haemoglobin in arterial blood.
