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).
oximetry. measurement of the oxygen content of arterial blood. pulse oximetry. use of a spectrophotoelectric instrument applied to the skin which measures pulse rate and the percentage of oxygenated and reduced hemoglobin.ximetry performed noninvasively, usually on the finger or ear lobe, in which the small increase in absorption of light during the systolic pulse is used to calculate oxygen saturation.
