摘要

Evaluates the accuracy of the pulse transit time method for determining diastolic blood pressure using intra-arterial blood pressure as a reference. First, the paper describes the method. Then it discusses two sets of measurements which were carried out to determine the accuracy of the method with cardiac operated patients and healthy young volunteers. The thus obtained accuracies were +0.7 mmHg ± 10.7 mmHg for the cardiac patients and -6.6 mmHg ± 10.5 mmHg for the young volunteers, respectively.
