Equipments Used To Measure Blood Pressure

2.8K
Direct Method
This invasive approach involves cannulating a peripheral artery. During each cardiac contraction, pressure generates mechanical motion within the catheter, transmitted through rigid, fluid-filled tubing to a transducer. This transducer converts mechanical motion into electrical signals displayed as waveforms on a monitor. An automatic flushing system prevents blood backflow. Due to the potential risk of unexpected arterial blood loss, this method is primarily used in intensive...

    Area of Science:

    • Biomedical Engineering
    • Optical Sensing
    • Physiological Monitoring

    Background:

    • Photoplethysmography (PPG) is a non-invasive optical technique.
    • Primarily used for blood oxygen saturation, PPG also estimates other physiological parameters.
    • This review focuses on parameters derived solely from the PPG waveform.

    Purpose of the Study:

    • To review physiological parameter estimations using PPG waveform analysis.
    • To discuss methods, signal processing, and validity of PPG-based measurements.
    • To highlight future research directions for non-invasive wearable devices.

    Main Methods:

    • Review of existing literature on PPG waveform analysis.
    • Discussion of signal processing techniques for physiological parameter extraction.
    • Comparison of PPG-derived results with gold standard measurements.

    Main Results:

    • PPG waveform analysis enables estimation of heart rate, lipid profiles, blood glucose, ankle brachial pressure, and respiratory rate.
    • Validity of these optical measurement techniques has been assessed against gold standards.
    • Part 2 of the review covers estimations requiring additional input measurements.

    Conclusions:

    • PPG is a valuable tool for non-invasive physiological monitoring beyond blood oxygen saturation.
    • Further research into wearable PPG devices can enhance remote and continuous health assessment.
    • The review provides a foundation for understanding PPG's capabilities and future potential.
