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).
Pulse oximeters are medical devices used to measure the oxygen level (or oxygen saturation) in the blood. Pulse oximeters are considered to be a noninvasive, painless, general indicator of oxygen delivery to the tissues (e.g., finger, earlobe, forehead, toe or nose).isks of using a Pulse Oximeter. Pulse oximetry is a quick, noninvasive method of measuring oxygen saturation in the blood. Risks associated with using a pulse oximeter are minimal and rare. Prolonged application of the probe may cause tissue breakdown at the application site.
