Abstract

The provision of sufficient oxygen to the brain is a major goal for neonatologists to prevent major neuro-developmental handicaps and to improve the chances for intact survival of sick newborn infants. In this paper the authors present the theory and design of a new noninvasive device for transcutaneous monitoring of cerebral blood and tissue oxygenation using a differential absorption laser system. The new technique depends upon illuminating the head of the neonate with radiation from six near infrared laser diodes. The choice of the used laser wavelengths (775, 780, 810, 825, 830, 850 nanometers) follows the principles of near infrared spectroscopy for obtaining accurate measurements. Different constructions of fiber optic probes arranged around the head of the neonate along the biparietal diameter guide the transmitted and received laser signals for signal processing. The detailed description and operating characteristics of this system are presented.
