Validation of the Omron 705IT (HEM-759-E) oscillometric blood pressure monitoring device according to the British Hypertension Society protocol

There is some inconsistency in the recommendations by scientific societies on the issue of miscuffing.

“However, there is some inconsistency in the recommendations by scientific societies on the issue of miscuffing [1,4,90,98–100].”

A device that has been successfully validated in a general population sample might not be accurate in a special population such as children, pregnancy, atrial fibrillation, chronic kidney disease, or arm circumference greater than 42 cm.

“A device that has been successfully validated in a general population sample might not be accurate in a special population [children, pregnancy, atrial fibrillation, chronic kidney disease (CKD), arm circumference >42 cm]”

In 2018, the AAMI, ESH and ISO developed a single universally acceptable standard, AAMI/ESH/ISO, ISO 81060-2:2018, intended to replace all previous protocols.

“In 2018, the AAMI, ESH and ISO developed a single universally acceptable standard (AAMI/ESH/ISO, ISO 81060-2:2018), which is intended to replace all previous protocols [90].”

Current recommendations for manual auscultatory devices require a cuff with the length of the inflatable bladder covering 75-100% of the mid-arm circumference and the width covering 37-50% of the length of the mid-arm.

“Current recommendations for manual auscultatory devices require a cuff with the length of the inflatable bladder covering 75–100% of the mid-arm circumference of the individual and the width covering 37–50% of the length of the mid-arm [90,98].”

For automated oscillometric upper arm-cuff devices, the cuff is also the signal sensor and each cuff size should be validated in an adequate number of individuals according to the validation standard used.

“For automated oscillometric upper arm-cuff devices, the cuff is also the signal sensor and each cuff size should be validated in an adequate number of individuals according to the validation standard used [90,98].”

The rules for the dimensions of the inflatable bladder do not necessarily apply for oscillometric devices, and the accuracy of each oscillometric device should be assessed in association with the recommended cuff size in validation studies.

“The above-mentioned rules for the dimensions of the inflatable bladder do not necessarily apply for oscillometric devices, and the accuracy of each oscillometric device should be assessed in association with the recommended cuff size in validation studies [90,98].”

An automated oscillometric device successfully validated in adults may not be accurate in children.

“An automated oscillometric device, which has been successfully validated in adults may not be accurate in children [90,91,182]”

An automated oscillometric device successfully validated in adults may not be accurate in pregnancy or preeclampsia.

“An automated oscillometric device, which has been successfully validated in adults may not be accurate in pregnancy or preeclampsia [90,191]”

A new Universal Standard for validation of BP monitors has been published in 2018.
