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).
What is pulse oximetry? Pulse oximetry is a noninvasive method that enables the measurement of a personâs blood oxygen saturation, which is often referred to as SpO2 or âThe Fifth Vital Signâ (the first 4 being your pulse, temperature, blood pressure and respiratory rate).hat is pulse oximetry?
