[An evaluation of the Spacelabs 90207 model of the ambulatory arterial pressure monitoring system].
BACKGROUND
The aim of the present study was to validate the SpaceLabs 90207 apparatus used in non-invasive outpatient monitoring of blood pressure.


METHODS
The measurements of blood pressure (BP) and cardiac frequency (CF) obtained with the SpaceLabs monitor were compared with those obtained with a mercury sphygmomanometer used as the reference method in 86 patients with a wide range of ages and BP. The differences between both methods of measurement were quantified by a previously protocolized grade system from the British Hypertension Society (BHS).


RESULTS
The mean of the differences between both systems of reading was 1.59 +/- 5.9 mmHg for systolic BP (SBP) 1.05 +/- 4.4 mmHg for diastolic BP (DBP) and -0.64 +/- 2.55 beats per minute for the CF. The accumulated percentage of differences of BP less than or equal to 5, 10 and 15 mmHg was of 74, 89 and 96%, respectively corresponding to grade B according to the validation protocol of the BHS. Grade B was obtained in all the interval differences of BP except within the range of DBP greater than or equal to 100 mmHg which showed grade A. Grades A or B were obtained in all the age groups except for grade C in the SBP of subjects over the age of 65.


CONCLUSIONS
The SpaceLabs 90207 monitor satisfies the criteria of internationally accepted validation criteria, therefore, its use can be recommended for the outpatient blood pressure measurement.
