title: Validation of the Health & Life HL168JD wrist blood pressure monitor for home blood pressure monitoring according to the International Protocol.
abstract: OBJECTIVE
  This study aimed to evaluate the accuracy of the automated Health & Life oscillometric wrist blood pressure monitor HL168JD for home blood pressure monitoring according to the European Society of Hypertension International Protocol.
  
  
  METHODS
  Systolic and diastolic blood pressures were sequentially measured in 33 adult Chinese using the mercury sphygmomanometer (two observers) and the HL168JD device (one supervisor). Ninety-nine pairs of comparisons were obtained from 15 participants in phase 1 and further 18 participants in phase 2 of the validation study. Data analysis was performed using the ESHIP Analyzer program.
  
  
  RESULTS
  The HL168JD device successfully passed phase 1 of the validation study with a number of absolute differences between device and observers within 5, 10, and 15 mmHg for at least 33/45, 41/45, and 45/45 measurements, respectively. The device also achieved the targets for phase 2.1, with 71/99, 90/99, and 98/99 differences within 5, 10, and 15 mmHg, respectively, for systolic blood pressure, and with 73/99, 89/99, and 99/99 within 5, 10, and 15 mmHg, respectively, for diastolic blood pressure. In phase 2.2, 27 and 26 participants had at least 2 of the 3 device-observers differences within 5 mmHg for systolic and diastolic blood pressure, respectively.
  
  
  CONCLUSIONS
  The Health & Life wrist blood pressure monitor HL168JD can be recommended for home use in adults.
