Intravascular Electronic Manometer

Development of an electronic manometer for intrapleural pressure monitoring.

BACKGROUND Measurement of intrapleural pressure is useful during various pleural procedures. However, a pleural manometer is rarely available. OBJECTIVES The aim of this study was to (1) construct an electronic pleural manometer, (2) assess the accuracy of the measurements done with the new device, (3) calculate the costs of the manometer construction and (4) perform an initial evaluation of ...

Integrated Digital Manometer for Lumbar Puncture

U-Tube Manometer Calibration using ANFIS

This paper deals with the implementation of the Adaptive neuro fuzzy inference system (ANFIS) on a Xilinx based Field Programmable Gate Array Spartan-3E. The implemented hardware is then used to efficiently calibrate the U-Tube manometer, in which the relation between the level of mercury and the Capacitance developed across the Copper Plates of the manometer is highly non-linear. This system s...

An intracardiac manometer: its evaluation and application.

The miniature intracardiac manometer supplied a method for recording artefact-free pressure tracings from the heart and great vessels of man and the intact animal. This instrument has been applied to the procedure of cardiac catheterization. It has also been used to demonstrate that if motion artefacts can be minimized, the central pulse can be recorded with reasonable accuracy by means of mano...

Study on a Concentric Tube Bulb Manometer and its Performance Compared to U-shaped Manometer

This paper presents comparative study of a new type of manometer calledconcentric tube bulb (C.T.B) manometer. Its performance of measuring differential heightis studied against conventional U-shaped manometer. Pressure drops and mass flow ratesare calculated by taking various systems comprising of different flow measuring devicessuch as orifice and venturimeters using both U- shaped and C.T.B ...
