Krypton Filled Flashlamp: A Possible New Light Source for Near Infrared Spectroscopy in vivo
Hypoxic brain damage of newborn infants is the prominent problem of perinatal medicine. Research in this field is limited, because new techniques for measuring the oxygen supply to brain cells are still in development. There is a need for further improvement of existing techniques and for a simplification of the measuring systems and their applicability. Near infrared (NIR) spectroscopy in vivo has been shown to be a powerful tool for non-invasive monitoring of several cerebral parameters, e. g. changes in blood oxygenation or blood volume. Since Jöbsis’ (1977) first description of this technique marked improvements could be achieved by a number of workers. Recent progress by Cope and Delpy (1988) lead to new clinical applications as the quantitative estimation of cerebral blood flow.
