SAMMENDRAG
Blodtrykksmåling med kvikksølvmanometer etter standardiserte prosedyrer, har lenge vært en epidemiologisk
referansemetode. Dinamap er en automatisert blodtrykksmåler som måler trykk og hjertefrekvens på
grunnlag av oscillometri og moderne elektronikk. Før Statens helseundersøkelser (SHUS) tok i bruk
Dinamap på slutten av 80-tallet, ble blodtrykk målt med kvikksølvmetoden (Erkameter) sammenlignet med
blodtrykk målt med Dinamap – i en screening situasjon. Vi fant at Dinamap var et velegnet screeningverktøy.
Systolisk blodtrykk ble målt omtrent likt med de to metodene, Dinamap viste seg å måle diastolisk
trykk noe lavere enn Erka. Forskjellen Erka–Dinamap avtok med økende målenivå.

ENGLISH SUMMARY
Blood pressure measurements with a sphygmomanometer in accordance with standardized methods, has
been an epidemiological reference method for a long time. Dinamap is a method of measuring blood
pressure automatically, recording both pressure and heart frequency on the basis of oscillometry and
modern electronics. Before the National Health Screening Service started using Dinamap, at the end of the
eighties, blood pressure was measured with the mercury method (Erkameter) and compared to blood
pressures measured with Dinamap – in a screening situation. We then found that Dinamap was a well
suited screening tool. Systolic blood pressure measurements were about the same with the two methods,
for diastolic pressure Dinamap showed slightly lower values than Erka. The difference Erka–Dinamap
diminished at higher measurement levels.
