PURPOSE OF REVIEW Recent advances in pulse oximetry have made it possible to noninvasively measure total hemoglobin, as well as the two most common dyshemoglobins. This review will trace the development and clinical application of multiwavelength pulse oximetry. RECENT FINDINGS Until now, commercially produced pulse oximeters have utilized two wavelengths of light and could measure only the r...

Cerebral oximetry has been around for some 3 decades but has had a somewhat checkered history regarding application and reliability. More recently several monitors have been approved in the United States and elsewhere and the technique is emerging as a useful tool for assessing not only adequate cerebral oxygenation but also tissue oxygenation and perfusion in other organs.

IMPORTANCE Critical congenital heart disease (CCHD) was added to the Recommended Uniform Screening Panel for Newborns in the United States in 2011. Many states have recently adopted or are considering requirements for universal CCHD screening through pulse oximetry in birth hospitals. Limited previous research is directly applicable to the question of how many US infants with CCHD might be iden...

Incorporating of the new pulse oximetry feature into computer-aided fetal monitoring system requires a lot of modifications in hardware and software structure of the system. Since these modifications are fairly time-consuming, such a solution would be impracticable during preliminary testing and evaluation phases of new medical instrument. Therefore, at first we decided to build a prototype sys...

Objectives: To detect Congenital Heart Diseases (CHD) at an early stage and to find out its occurrence in asymptomatic healthy term newborns. To assess the role of pulse oximetry as a screening tool in CHD. Methods: All apparently healthy newborns delivered in a period of 1 year in Krishna Institute of Medical Sciences, Karad were screened for the presence of CHD by physical examination and pul...
