[Automatic non-invasive blood pressure determination--comparative determinations and experiences with the DINAMAP Vital Data 845 XT Monitor in the intensive care station].
An improved version of a well-established monitor for the noninvasive measurement of blood pressure and heart rate was tested in critically ill patients in an operative intensive care-unit. The device utilizing the oscillometric method and a microprocessor proved to be safe, reliable and sufficiently precise for long-term monitoring. Data were shown clearly on a lighted digital display. Individual factors had much influence on the measurement. Deviations from intraarterial measurement occurred in the same patient almost permanently in one direction, but alterations of blood pressure were read out precisely. Irrespective of the individual influence, mean arterial pressure (MAP) and diastolic blood pressure were indicated too high, and the systolic pressure was recorded to low above 150 mmHg (= 20 kPa) and too high below 100 mmHg (= 13.3 kPa) obtained by the invasive method.
