The document updates WHO’s 2005 guidance on blood pressure measuring devices (BPMDs). It also responds to concern about the lack of accurate, good-quality devices, especially in low-and middle-income countries (LMIC) through technical consultation and expert review. The focus of the publication is on automated non-invasive BPMDs with cuff, including characteristics, regulatory requirements and standards, calibration as well as maintenance. It also provides guidance on procurement, decontamination and decommissioning. Additional elements on accurate measurement of BP and training for personnel are included.
