ABSTRACT
To (1) assess the accuracy of the Uscom BP+ oscillometric upper-arm professional blood pressure (BP) monitor in children and adolescents as per the AAMI/ESH/ISO Universal Standard (ISO 81060-2:2018); (2) assess the suitability of a non-standard cuff; and (3) assess the impact of motion artefact on device accuracy and precision. Children and adolescents were recruited to fulfil the sex/cuff distribution criteria of the Universal Standard. Single arm sequential BP measurements were used, the test device measured on deflate with an altered child/adolescent algorithm, using three standard (Extra Small, Small Adult, Adult) and, as exploratory analysis, additionally in one non-standard cuff (Wide Range; WR) (arm circumferences: 12-17, 16-24, 22-32, 22-42 cm, respectively). The presence of motion artefact was determined and its impact on BP assessed. One-hundred-forty participants were recruited with 123 included for analysis. When using the Extra Small, Small Adult and Adult cuffs only, the BP+ passed both criteria (95 participants, 321 pairs, -0.1 ± 7.3/ – 1.6 ± 7.6 and 5.72/6.50 mmHg systolic/diastolic) (reference thresholds: ≤5 ± 8, ≤6.95/6.76, respectively). The inclusion of the WR cuff showed unacceptable imprecision, and motion artefact had a substantial influence on test device precision. The Uscom BP+ fulfilled the requirements of the Universal Standard in children and adolescents when using the altered algorithm with the three standard cuffs and can be recommended for clinical use. The WR cuff cannot be recommended in this population in measure-on-deflate mode due to its imprecision. Additionally, BP measurement accuracy in children and adolescents can be improved through inclusion of a motion artefact detection system.
