Validation of A&D TM-2430 upper-arm blood pressure monitor for ambulatory blood pressure monitoring in children and adolescents, according to the British Hypertension Society protocol

Blood Press Monit. 2012 Apr;17(2):76-9. doi: 10.1097/MBP.0b013e328351d4a4.


Objective: The A&D TM-2430 ambulatory blood pressure (BP) monitor has been validated in adults but not in a young population. We sought to validate the device monitoring in children and adolescents, according to the British Hypertension Society (BHS) protocol.

Methods: The A&D TM-2430 is an automated oscillometric upper-arm device for ambulatory BP monitoring. Nine consecutive measurements were taken in 61 children (mean age, 9.8 years; range, 5-15 years) according to the BHS criteria. Overseen by an independent supervisor, measurements were recorded by two observers blinded from each other's readings and from the device readings.

Results: The mean difference ± SD between the observers and device measurements was 0.73 ± 1.64 mmHg for systolic blood pressure (SBP) and -1.23 ± 1.65 mmHg for diastolic blood pressure (DBP), respectively, with an interobserver difference of 4 mmHg. The cumulative percentages of differences within 5, 10, and 15 mmHg were 89, 95, and 98% for SBP and 67, 88, and 98% for DBP. The device achieved a grade A rating for SBP and a B grade for DBP.

Conclusion: The A&D TM-2430 upper-arm BP monitor has fulfilled the required BHS standards and can be recommended for measuring ambulatory BP in children and adolescent populations.
