ISO/TC 121/SC 3/JWG 7 - Joint ISO/TC 121/SC 3-IEC/SC 62D WG : Non-invasive blood pressure monitoring equipment

This document specifies the requirements and methods for the clinical investigation of continuous automated non-invasive sphygmomanometers used for the measurement of the blood pressure of a patient. This document does not cover usability aspects such as the form and manner of the data display or output. This document does not specify a numerical threshold on the minimum output period. A continuous automated non-invasive sphygmomanometer providing blood pressure parameters (e.g., systolic blood pressure, diastolic blood pressure or mean arterial pressure) with an output period considerably larger than 30 s is not typically considered a continuous automated non-invasive sphygmomanometer. This document covers both trending continuous automated non-invasive sphygmomanometers and absolute accuracy continuous automated non-invasive sphygmomanometers and focuses solely on requirements for the clinical investigation. Representation of output is not covered by this document. NOTE 1 IEC 62366-1 provides requirements on the application of usability engineering to medical devices. The usability engineering process can be used to clarify for the intended user whether the displayed data concerns absolute accurate values or trending values. The requirements and methods for the clinical investigation of continuous automated non-invasive sphygmomanometers provided in this document are applicable to any subject population, and any condition of use of the continuous automated non-invasive sphygmomanometers. NOTE 2 Subject populations can, for example, be represented by age or weight ranges. NOTE 3 This document does not provide a method to assess the effect of artefacts during the clinical investigation (e.g. motion artefacts induced by the movement of the subject or the movement of the platform supporting the subject). This document specifies additional disclosure requirements for the accompanying documents of continuous automated non-invasive sphygmomanometers that have undergone clinical investigation according to this document. This document is not applicable to: — the clinical investigation of a non-automated sphygmomanometer as given in ISO 81060-1, — the clinical investigation of an intermittent automated non-invasive sphygmomanometer as given in ISO 81060-2, — an automated non-invasive sphygmomanometer as given in IEC 80601-2-30, or — invasive blood pressure monitoring equipment as given in IEC 60601‑2‑34.

This document specifies requirements for the repeatability and reproducibility of non-invasive blood pressure (NIBP) simulators intended to test automated sphygmomanometers utilizing the oscillometric non-continuous method only. In addition, the pulse rate set on the NIBP simulator is tested. This document is not intended to relate the signals, generated by the NIBP simulator, to the oscillometric signal recorded in a cuff attached to a human. It does not intend to test the interaction between the NIBP simulator and the tested automated sphygmomanometer (e.g. the agreement of the set values of the NIBP simulator and the displayed values of the tested automated sphygmomanometer or the properties of the cuff and tubing, such as design or elastic properties). NOTE 1 These parameters can be tested separately in a clinical investigation or by using different special test setups. This document does not check whether or not the NIBP simulator is able to test the accuracy of the absolute blood pressure value of oscillometric automated sphygmomanometers. NOTE 2 Usually this is tested by a clinical investigation according ISO 81060-2 or other protocols. This document is applicable to NIBP simulators testing automated sphygmomanometers for adults, children and neonates at the upper arm, thigh etc. and automated sphygmomanometers measuring at the wrist.

This document specifies the requirements and methods for the clinical investigation of me equipment used for the intermittent non-invasive automated estimation of the arterial blood pressure by utilizing a cuff. This document is applicable to all sphygmomanometers that sense or display pulsations, flow or sounds for the estimation, display or recording of blood pressure. These sphygmomanometers need not have automatic cuff inflation. This document covers sphygmomanometers intended for use in all patient populations (e.g. all age and weight ranges), and all conditions of use (e.g. ambulatory blood pressure monitoring, stress testing blood pressure monitoring and blood pressure monitors for the home healthcare environment for self-measurement as well as use in a professional healthcare facility). EXAMPLE Automated sphygmomanometer as given in IEC 80601-2-30 undergoing clinical investigation according to this document. This document specifies additional disclosure requirements for the accompanying documents of sphygmomanometers that have passed a clinical investigation according to this document. This document is not applicable to clinical investigations of non-automated sphygmomanometers as given in ISO 81060-1 or invasive blood pressure monitoring equipment as given in IEC 60601-2-34. This document is not applicable to clinical investigations of a set of cuffs that are not of same materials and construction. Each type of cuff set is required to be evaluated separately according to this document.

ISO 81060-2:2013 specifies the requirements and methods for the clinical investigation of me equipment used for the intermittent non-invasive automated estimation of the arterial blood pressure by utilizing a cuff. ISO 81060-2:2013 is applicable to all sphygmomanometers that sense or display pulsations, flow or sounds for the estimation, display or recording of blood pressure. These sphygmomanometers need not have automatic cuff inflation. ISO 81060-2:2013 covers sphygmomanometers intended for use in all patient populations and all conditions of use. ISO 81060-2:2013 specifies additional disclosure requirements for the accompanying documents of sphygmomanometers that have undergone clinical investigation according to ISO 81060-2:2013.

ISO 81060-2:2009 is applicable to all sphygmomanometers that sense or display pulsations, flow or sounds for the estimation, display or recording of blood pressure. These sphygmomanometers need not have automatic cuff inflation. ISO 81060-2:2009 covers sphygmomanometers intended for use in all patient populations (e.g. all age and weight ranges), and all conditions of use (e.g. ambulatory blood pressure monitoring, stress testing blood pressure monitoring and blood pressure monitors for the home healthcare environment or self-measurement). ISO 81060-2:2009 specifies additional disclosure requirements for the accompanying documents of sphygmomanometers validated according to this International Standard.
