Validation of the FF680 upper-arm blood pressure monitor according to the ISO 81060-2:2018

This study evaluated the accuracy of blood pressure measurement in adults using FF680 electronic blood pressure monitors with the Korotkoff-Sound method, in accordance with the ISO 81060-2:2018. The study was conducted at Shijiazhuang People's Hospital and lasted 56 days, from 26 May to 21 July 2023. Participants, drawn from an adult demographic, underwent data verification and analysis with strict adherence to the trial protocol. For the FF680 electronic blood pressure monitor using the Korotkoff-Sound method, data from 85 valid participants were analyzed. The findings revealed mean differences (SDs) of -0.66 mmHg (2.45 mmHg) for SBP and -0.28 mmHg (2.09 mmHg) for DBP. SBP and DBP had SDs of ≤6.9 and ≤6.95 mmHg, meeting the standard requirements. FF680 devices are recommended for adult blood pressure monitoring because they meet the ISO 81060-2:2018.
