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 ...

THE method about to be described secures a correct record of any part of the intracardiac pressure curve, for it meets the theoret-Fig. 1.-Scheme illustrating the arrangement of the apparatus. The meaning of the abbreviations is given in the text. ieal requirements of a perfect method, in that it employs an incom-pressible fluid and at the same time practically does away with the inertia error....

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 ...

Objective To assess the prevalence of obesity and elevated blood pressure in a suburban population of middle school and high school student athletes and examine the differences from the previously published populations. Study design The Student Athlete Cardiac Evaluation Registry Study is a single-centre, community hospital-based registry study, that provided free annual preparticipation phys...

INTRODUCTION Pleural manometry during large-volume thoracentesis can prevent the development of excessively negative pleural pressures, which have been associated with re-expansion pulmonary edema; can diagnose an unexpandable lung; and can predict pleurodesis success. We currently perform pleural manometry simultaneously with both a vertical-column water manometer with an interposed resistive ...
