Measurement of Fluid Pressure01:16

Measurement of Fluid Pressure

360
Fluid pressure is commonly measured using devices called manometers, which rely on liquid columns to indicate pressure differences. The height of a liquid column in a manometer reflects the pressure exerted by the fluid, providing a simple yet effective means of measurement. Different types of manometers serve specific purposes based on their configurations and the type of fluids involved.
A basic form of manometer is the piezometer, a vertical tube open at the top and filled with the same...

Pressure Gauges01:20

Pressure Gauges

4.4K
Most pressure gauges, like those on scuba tanks, are calibrated to read zero at atmospheric pressure. Readings from such gauges are called the gauge pressure, which is the pressure relative to atmospheric pressure. When the pressure inside the tank exceeds atmospheric pressure, the gauge reports a positive value. Some gauges are designed to measure negative pressure. For example, many physics experiments must take place in a vacuum chamber, a rigid chamber from which some of the air is pumped...

Design Example: Strain Gauge Bridge or Wheatstone Bridge

672
The utilization of strain gauges as transducers for converting mechanical strain into electrical signals is a common practice in various engineering applications. These strain gauges are frequently integrated into Wheatstone bridge circuits to accurately measure parameters such as force or pressure. Within this context, each element within the circuit exhibits a resistance that undergoes subtle variations when subjected to mechanical strain. The primary objective is to convert minuscule...

Area of Science:

  • Cardiovascular research
  • Medical device technology
  • Interventional cardiology

Background:

  • Fractional flow reserve (FFR) is crucial for assessing coronary artery stenosis severity.
  • Advancements in pressure sensor technology aim to improve FFR measurement reliability and handling.
  • Optical pressure sensors offer a potential alternative to traditional piezoresistive sensors.

Purpose of the Study:

  • To evaluate the reliability and handling of the OptoWire Deux optical pressure sensor.
  • To compare the OptoWire Deux against PressureWire X and Verrata Pressure wire (piezoresistive sensors).
  • To assess measurement drift and qualitative handling characteristics of different FFR wires.

Main Methods:

  • Single-center study involving 80 patients undergoing coronary angiography.
  • FFR measurements were performed using OptoWire Deux, PressureWire X, and Verrata Pressure wire.
  • Drift was defined as Pd/Pa differing from 1.00 ± 0.02 post-measurement.
  • Handling was qualitatively assessed for steerability and torqueability.

Main Results:

  • OptoWire Deux demonstrated stable and reliable FFR measurements with significantly less drift (11%) compared to PressureWire X (37%) and Verrata (33%).
  • OptoWire Deux exhibited superior handling, rated higher for steerability and torqueability.
  • PressureWire X handling was rated equally good, while Verrata was rated inferior.

Conclusions:

  • The OptoWire Deux provides stable and reliable FFR measurements with reduced drift.
  • OptoWire Deux offers advantageous handling characteristics for interventional procedures.
  • Optical sensor technology shows promise for enhancing FFR assessment accuracy and usability.
