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 oximetry is a useful tool for assessing oxygen saturation, but it doesn't provide a complete picture of your patient's respiratory status. Understanding what pulse oximetry can and can't do will help you to use this technology wisely.o interpret pulse oximetry values correctly, you need to understand the oxyhemoglobin dissociation curve, which illustrates the relationship between arterial oxygen saturation (for our purposes, SpO 2 or SaO 2) and the amount of oxygen that is dissolved in the blood (partial pressure of oxygen, PaO 2).
