oximetry

 [ok-sim´ĕ-tre]
measurement of oxygen saturation of the blood using an oximeter.
pulse oximetry a noninvasive method of indicating the arterial oxygen saturation of functional hemoglobin, using a pulse oximeter.

ox·im·e·try

(ok-sim'ĕ-trē),
Procedure using a device to measure oxygen saturation by fluctations of light absorption in well-vascularized tissue during systole and diastole. The underlying principle is the Beer law, or the relationship between the amount of light absorbed by a solute in solution and the concentration of the unknown solute.

oximetry

/ox·im·e·try/ (ok-sim´ĕ-tre) determination of the oxygen saturation of arterial blood using an oximeter.

oximetry

a photodiagnostic method of monitoring arterial blood oxygen saturation (SaO2). Oximetry is commonly used to titrate levels of oxygen in hospitalized patients. It is used for monitoring the patient's oxygenation status during the perioperative period or any other time of heavy sedation, during mechanical ventilation, and in many clinical situations such as pulmonary rehabilitation programs and stress testing. See also pulse oximeter.

oximetry

(1) Measurement of oxygen saturation of blood by laboratory techniques.
 (2) An obsolete bedside test for determining oxygen saturation by evaluating the colour of blood as it passes through a translucent tissue—e.g., the pinna of the ear.

ox·im·e·try

(ok-sim'ĕ-trē)
Measurement with an oximeter of the oxygen saturation of hemoglobin in a sample of blood.

ox·im·e·try

(ok-sim'ă-trē)
Measurement with an oximeter of the oxygen saturation of hemoglobin in a sample of blood.

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.

As seen in Figure 1, options on the form for the pulse oximetry screening were: pass, fail, not screened, and NICU (neonatal intensive care unit).
Too many babies have been discharged from hospitals without proper pulse oximetry screening, only to die or require last-minute, emergency life-saving procedures," said Annamarie Saarinen, co-founder and CEO of the Newborn Foundation, and the mother of Eve, who was diagnosed at 48 hours old with CCHD.
Screening for CCHD by pulse oximetry is relatively inexpensive and uncomplicated.
The present study primarily aimed to determine trends and reference values for pre-ductal and postductal oxygen saturation by pulse oximetry during the first 60 min of life in healthy full-term infants born at moderate altitude.
Nurses indicated that pulse oximetry was a familiar skill and screening all newborns was easily incorporated into their routine tasks.
Lest I he accused of all doom and gloom regarding neonatal pulse oximetry, I have good news.
While doctors stressed the need for more paediatric cardiologists, they added that the pulse oximetry significantly reduces the chance of an affected baby being undiagnosed.
