Abstract | A great many potentially useful data are available in the neonatal intensive care unit (NICU) in analog form, that is, time-varying signals from pressure transducers, impedance sensors, or bioelectric potentials. Although the instruments commonly used to process these signals are becoming more sophisticated, most commercially available monitors extract only simple parameters, such as heart rate or blood pressure, and sound an alarm if preset limits are violated. We [the authors] at Vanderbilt University are attempting to use computers, on a research basis, to extract more useful information about the patient by processing the signals from relatively noninvasive physiologic sensors. We are also involved in using statistical models to characterize a given patient population as to probable course and outcome on the basis of linear discriminant function analysis of a few variables observed at specific times. |
