To validate the noninvasive blood pressure monitoring function of the EDAN elite V5 patient monitor with reference invasive blood pressure monitoring equipment for clinical use in adults, adolescents or children according to the International Organization for Standardization (ISO) 81060-2:2018 standard.

Patients were recruited, and the ipsilateral sequential method was used for blood pressure measurement according to the standard. The validation results were assessed following the protocol and the Bland–Altman scatterplot was used to show the difference between the test device and reference invasive blood pressure results.

A total of 71 patients were included in the study, with 35 and 36 patients for each iFAST and iCUFS mode, respectively. The validation results showed an average device-reference difference of −3.27 ± 5.60 mmHg for SBP and −0.09 ± 6.10 mmHg for DBP for the iFAST mode, and −2.04 ± 5.55 mmHg for SBP and −0.79 ± 5.86 mmHg for DBP for the iCUFS mode, respectively, which passed the criteria of the ISO 81060-2 : 2018 in adults, adolescents or children population for both SBP and DBP.

The noninvasive blood pressure monitoring function of the EDAN elite V5 patient monitor passed all the requirements of ISO 81060-2:2018 and can be recommended for clinical use in adults, adolescents, or children.
