title: Computerized transcutaneous monitoring incorporating laser Doppler velocimetry.
abstract: Measurements of transcutaneous oxygen tension, transcutaneous carbon dioxide tension, transcutaneous heater power, transcutaneous electrode temperature, and peripheral perfusion at the gas measurement site (assessed by laser Doppler velocimetry) are monitored by a microprocessor-based data acquisition system. Arterial blood pressure, central venous pressure, pulmonary artery pressure, respiration rate, and heart rate may be simultaneously captured with the system unattended for 12-hour intervals. This computerized monitoring system is mobile and easily applied by medical technologists to adult or neonatal intensive care patients. Simultaneous collection of the measurement data has facilitated research on the interrelationships of the measured parameters. It should be helpful in assessing optimal therapeutic interventions as well as the changing physiology of acutely ill patients.
