oximetry

A recent review undertaken by NHS England recommended to the UK National Screening Committee (UK NSC) against using pulse oximetry as an additional test in the newborn and infant physical exam (NIPE).

In the USA, where pulse oximetry screening is routine, death from critical heart defects has been reduced by one third in babies offered the screening.

Nonetheless, it can also be measured by pulse oximetry.[1] Pulse oximetry is normally used for checking SpO[sub]2 and is very useful in rural communities or developing countries.[2] Normal pulse oximetry readings range from 95% to 100% at the sea level.[2] SpO[sub]2 can be defined as the fraction of SpO[sub]2 hemoglobin to that of total hemoglobin in the blood.[3] Pulse oximetry is used in determining the percentage of oxygen bound to hemoglobin in the blood.[3],[4],[5],[6],[7],[8],[9],[10],[11] The pulse oximeter consists of a small device which sticks to the body such as a finger, earlobe, or foot and shows its readings through wireless.

The purpose of the present study was to evaluate the use of pulse oximetry in the assessment of fingertip perfusion using handheld Doppler probe as the reference standard.

Red Cross War Memorial Children's Hospital (RCWMCH), a tertiary paediatric hospital in the Western Cape Province, SA, introduced overnight oximetry as a screening tool for OSA in 2012 with the aim of prioritising children requiring urgent intervention.

Cerebral oximetry leading up to cardiac arrest: A marker of the impact of mean arterial pressure on the brain, but not time of death.

Aim of this study is to find out whether this pulse oximetry method (disappearance and/or reappearance of plethysmographic waves and/or average of both) can reliably be used for measuring BP of neonates.

Conclusion: The measurement of pre-and post-ductal oxygen saturation by pulse oximetry was an effective screening tool for the detection of critical congenital heart defects in newborns.

Specific wavelengths of ?P=660nm & 940nm with narrow spectral bandwidths provide the perfect LED solution for pulse oximetry applications.

Additionally, the regional oximetry may help clinicians monitor cerebral oxygenation in situations in which pulse oximetry alone may not be fully indicative of the oxygen in the brain due to various factors, such as the type of clinical procedure being performed, concluded the company.
