YY 0670-2008Non-invasive automated sphygmomanometer (English PDF)

1.1 Standard equipment includes

This standard applies to the use of oscillometric or other similar methods to complete the non-invasive blood pressure measurement or electronic sphygmomanometer having this feature other devices. Including all through cuff inflation, deflation, and by means of vibration generated by the flow of sound to measure, display and record blood pressure instrument.

This standard covers all blood pressure measuring apparatus from newborns to adults of all ages.

This standard also applies to ambulatory blood pressure monitoring. Such patients may carry equipment worn or carried, or activities of daily living may be in the process Repeated measurement of blood pressure and heart rate, and save the results obtained.

Note: Appendix A contains the basic principles concerning the interpretation of the requirements of the standard and its provisions.

1.2 This standard does not include equipment

This standard does not apply to direct, invasive arterial blood pressure measurement devices.

This standard does not apply to the measurement of blood pressure by finger, thoracic impedance method for automated blood pressure monitor.

3.2 Auscultatory gap

Early sound auscultation auscultation between the late first phase and the second phase appears momentarily disappear.

Note: In some of the object, especially in patients with hypertension who, in the case of very high cuff pressure arm artery auscultation, auscultation sound disappears when the pressure is reduced.

When the pressure is reduced to a certain extent, the auscultation sound reappears. This often causes a low systolic blood pressure measurements, it may also cause diastolic Measuring high values.
