Validation of the Welch Allyn ProBP 3400: a device for modern medical practice.


OBJECTIVES As medical care evolves, automated sphygmomanometers must be able to provide accurate and timely blood pressure (BP) data to the healthcare provider. We evaluated the performance of a new hand-held, battery-operated device, the Welch Allyn ProBP 3400, to the AAMI SP 10 criteria. We also performed British Hypertension Society data analysis. METHODS A total of 111 (97 adults, 14 children) participants were tested using blinded and paired observers performing auscultation of Korotkoff (K1 and K5) sounds. RESULTS Ninety-two participants had acceptable data, giving 275 paired data sets for systolic BP (SBP) and diastolic BP (DBP) analyses. The mean ± standard deviation of the observer/device differences were -1.1 ± 7.5 mmHg for SBP and -2.1 ± 6.0 mmHg for DBP. These passed the AAMI SP10 requirements. The ProBP 3400 achieved an A grade for both SBP and DBP. CONCLUSION The ProBP 3400 passed the AAMI standard requirements and achieved A grade for both SBP and DBP. The device is less in cost and completely portable. It transmits BP data directly into the electronic medical record using a Universal Serial Bus connection. These features will improve the efficiency and accuracy of BP data available to clinicians, thus improving the quality of care.
