Non-invasive automated sphygmomanometer

1 Scope

This standard establishes safety and validity requirements for all sphygmomanometers, whether automated, or electronic, that are used with an occluding cuff for the indirect determination of arterial blood pressure.

1.1 Inclusions

This standard is applicable to electronic sphygmomanometer completing non-invasive blood pressure measurement via oscillography or other similar methods or other devices having such function, including all devices that inflate and deflate through cuff and sense or display pulsations, flow, or sounds in connection with the measurement, display, or recording of blood pressure.

This standard covers the blood pressure measurement devices for neonatal or newborn through adult categories.

Ambulatory blood pressure monitors, which are portable, lightweight, automated devices worn or carried by the patient that are able to obtain and store the results of repeated determinations of blood pressure and heart rate during activities of ordinary daily living, are included in this standard.

Note: For an explanation of the need for this standard and the rationale for its provisions, see annex A.

1.2 Exclusions

This standard is not applicable to devices for direct, intra-arterial measurement of blood pressure.

The use of automated monitors that measure blood pressure on the finger or through thoracic impedance are not covered in this standard.
