Clinic Blood Pressure Underestimates Ambulatory Blood Pressure in an Untreated Employer-Based US Population: Results From the Masked Hypertension Study.

Circulation·2016

Mercury sphygmomanometers are being phased out due to environmental concerns, not technological limitations. Current alternatives like aneroid and oscillometric devices have their own significant drawbacks, necessitating further research into advanced blood pressure monitoring techniques.

Area of Science:

  • Biomedical Engineering
  • Clinical Measurement
  • Environmental Health

Background:

  • Mercury sphygmomanometers, the clinical standard for blood pressure measurement, are being discontinued due to environmental concerns.
  • Existing alternatives, such as aneroid and oscillometric devices, present their own limitations, including observer error, mechanical drift, and inherent methodological constraints.
  • There is a need for reliable and accurate alternatives to mercury-based blood pressure monitoring.

Purpose of the Study:

  • To review the limitations of current blood pressure monitoring devices.
  • To explore potential alternative technologies to mercury sphygmomanometers.
  • To identify future directions for accurate and reliable blood pressure measurement.

Main Methods:

  • Review of existing literature on sphygmomanometer technologies.

  • Analysis of the advantages and disadvantages of mercury, aneroid, and oscillometric devices.
  • Discussion of emerging technologies like hybrid sphygmomanometers and wideband recording techniques.

    • Main Results:

    • Mercury sphygmomanometers, despite being the 'gold standard,' suffer from observer technique and maintenance issues.
    • Aneroid devices exhibit frequent deficiencies and are prone to observer technique errors.
    • Oscillometric devices eliminate observer error but may have inherent limitations preventing them from becoming the gold standard.
    • Hybrid and wideband recording techniques are proposed as potential, yet untested, alternatives.

    Conclusions:

    • The phase-out of mercury sphygmomanometers necessitates the development and validation of new blood pressure monitoring technologies.
    • Current alternatives do not fully replace the accuracy and reliability of mercury devices.
    • Further research into hybrid and wideband recording techniques is warranted to address the limitations of existing methods.
