Equipments Used To Measure Blood Pressure

Equipments Used To Measure Blood Pressure

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...

Measurement of Fluid Pressure

Measurement of Fluid Pressure

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...

Measurement of Blood Pressure

Measurement of Blood Pressure

Assessing blood pressure is a standard procedure executed in virtually all medical environments. The method utilized today was established over a hundred years ago by an innovative Russian doctor, Dr. Nikolai Korotkoff. The soft ticking noise, known as Korotkoff sounds, heard while taking blood pressure readings results from turbulent blood flow within the vessels. The apparatus required for this procedure includes a sphygmomanometer, a blood pressure cuff attached to a gauge, and a...

Area of Science:

Ophthalmology
Biomedical Engineering
Medical Devices

Background:

Accurate intraocular pressure (IOP) monitoring is crucial for glaucoma management.
IOP fluctuates daily and with heart rate, a phenomenon known as the ocular pulse.
Current monitoring methods may lack the precision needed for real-time therapeutic adjustments.

Purpose of the Study:

To report the measurement of the ocular pulse profile using a novel miniaturized IOP sensor.
To assess the sensor's accuracy and feasibility in an animal model.
To demonstrate a new method for continuous IOP monitoring.

Main Methods:

A miniaturized, passive interferometric IOP sensor was implanted in a New Zealand White rabbit eye.
The sensor measures ocular pulse variations without requiring an internal power source.
Ocular pulse profiles were recorded using both a DSLR and a smartphone reader.

Main Results:

The ocular pulse profile was successfully measured using the implanted sensor.
Measurements achieved an accuracy of +/- 0.15 mmHg.
The sensor effectively captured pressure variations up to 5 Hz.

Conclusions:

The developed interferometric IOP sensor enables accurate measurement of ocular pulse.
This technology offers a promising approach for continuous and precise IOP monitoring in glaucoma patients.
The use of external readers like smartphones suggests potential for user-friendly clinical application.
