Sleep States and Neonatal Pulse Oximetry

Neonatal and pediatric pulse oximetry.

The pulse oximeter has become a vital instrument in the care of infants and children with cardiopulmonary disease. Recent advances in pulse oximetry technology have improved some aspects of pulse oximeter performance. However, the reliability, accuracy, and clinical utility of pulse oximetry remain problematic in some types of patients under certain conditions. Improved signal processing techno...

Accuracy of pulse oximetry during neonatal resuscitation

A pilot study of neonatal and pediatric esophageal pulse oximetry.

BACKGROUND In this pilot study we explored the suitability of the esophagus as a new measuring site for blood oxygen saturation (Spo(2)) in neonates. METHODS A new miniaturized esophageal pulse oximeter has been developed. Five patients (one child and four neonates) were studied. RESULTS Spo(2) values were obtained in the esophagus of all patients. A Bland and Altman plot of the difference ...

Pulse Oximetry

The principal advantage of optical sensors for medical applications is their intrinsic safety since there is no electrical contact between the patient and the equipment. (An added bonus is that they are also less suspect to electromagnetic interference). This has given rise to a variety of optical techniques to monitor physiological parameters: for example, the technique of Laser Doppler veloci...
