A validation of the Mobil O Graph (version 12) ambulatory blood pressure monitor.
OBJECTIVE
To assess the clinical accuracy of the Mobil O Graph (version 12) ambulatory blood pressure monitor in an adult population.


METHODS
The accuracy of the device was assessed by predefined criteria (British Hypertension Society, BHS) in 85 subjects recruited from the patients and staff in a teaching hospital. A series of same-arm sequential blood pressure measurements were taken: first two observers taking simultaneous mercury readings, followed by a reading with the Mobil O Graph ambulatory monitor. A total of seven readings were taken from each subject in the sitting position. The data were then analysed according to the BHS protocol and the criteria of the Association for the Advancement of Medical Instrumentation (AAMI).


RESULTS
The Mobil O Graph ambulatory monitor fulfilled the criteria of the BHS protocol, achieving a grade B for systolic blood pressure (SBP) and a grade A for diastolic blood pressure (DBP). The mean differences were -2+/-8 mmHg for SBP and -2+/-7 mmHg for DBP. The device therefore also passed the AAMI standard (the mean to be within 5+/-8 mmHg).


CONCLUSIONS
The Mobil O Graph ambulatory monitor performed in a satisfactory manner according to the BHS and the AAMI criteria and can therefore be recommended for clinical use in the general population.
