oximeter

[äk′sim· əd·ər]
(medicine)
A photoelectric photometer used to measure the oxygenated fraction of the hemoglobin in blood which is either circulating in a particular tissue of an intact animal or human being, or during, or shortly after, its withdrawal from the vascular system, by observation of the absorption of light transmitted through or reflected from the blood.

Evaluation of accuracy of portable fingertip pulse oximeter, as compared to that of a hospital oximeter with digital sensor.
A plateau was defined as stable when the readings of the reference pulse oximeter manufactured by Nellcor oximeter (N-550, Nellcor Puritan Bennett Inc., Pleasanton, CA) have not changed more than 1% for 10 seconds.
Numerous studies have determined the accuracy of various pulse oximeter models, with literature reviews and meta-analyses concluding most devices have acceptable levels of agreement with arterial oxygen saturation levels in nonhypotensive patients (Giuliano & Higgins, 2005; Jensen, Onyskiw, & Prasad, 1998; Keogh & Kopotic, 2005; Nitzan, Romem, & Koppe, 2014; Soubani, 2001).
Oxygen saturation (the percentage of arterial blood that is bound with oxygen) and pulse rate (the number of times the heart beats per minute) provide an indication of lung and heart efficiency and increasingly are being measured with fingertip pulse oximeters for personal use.
Pulse oximeter proves to be an ideal device for an early recognition of hypoxia.
In the early 1990's I did some research for one of the pulse oximeter companies.
In July 2011, Lifebox donated 80 pulse oximeters to hospitals in Uganda.
There are no inexpensive portable pulse CO-oximeters on the market and a pulse oximeter cannot indicate impending carbon monoxide-related hypoxemia.
Members donated pounds 1,500 to the charity for research into the disease and purchased three oximeters.
The non-invasive nature of the oximeter was a revolution for the times, as we were all dealing with Universal Precautions, and seeking ways to avoid contact with human blood or other potentially infectious materials.
Working to develop a tabletop pulse oximeter, GE Healthcare engineers developed the TruSat pulse oximeter--a new product designed to be more durable and easier to use than similar products currently on the market.
Comparing S[O.sub.2] obtained by pulse oximetry with F[O.sub.2]Hb obtained by "CO-oximetry" in patients with high fractions of COHb or MetHb led to numerous reports erroneously stating that the oxygen saturation was greatly overestimated by the pulse oximeter in these patients.
