Noninvasive blood pressure measurements on the temporal artery

Systolic and diastolic blood pressures were recorded noninvasively on the temporal artery and compared with systolic and diastolic blood pressures obtained from the brachial artery. Both types of measurements were based on the detection of Korotkoff sounds. Data was collected from five subjects with the subjects lying in a supine position, sitting at rest. and sitting immediately after moderate exercise. This comparative study showed that both pressure measurements track each other within a difference margin of ±10%. which is comparable to the generally accepted accuracy of noninvasive blood pressure measurements.
