evaluation of a photo-electronic oscillometric method of blood pressure measurement [Omron HEM 815F]

ABSTRACT

Readings from an Omron HEM 815F portable blood pressure monitor and a Dinamap 8100 are compared to those obtained from a mercury column sphygmomanometer in this study. Results showed a bias of -3.6 and -2.8 mmHg for systolic and diastolic readings respectively with the Omron HEM 815F, compared to Dinamap 8100 which showed bias of +11.9 and -3.2 mmHg. The limits of agreement for the systolic readings were +/- 23.8 mmHg from the bias [mean difference] with the Omron HEM 815F, compared to +/- 21.8 mmHg with the Dinamap 8100. The Omron HEM 815F is a small monitoring device that produces readings of comparable accuracy to those produced by the Dinamap 8100
