Evaluation of a new electronic spirometer: the vitalograph "Escort" spirometer.

BACKGROUND The "Escort" spirometer is a lightweight, hand held spirometer employing a Fleisch pneumotachograph. Measurements of forced expiratory volume in one second (FEV1), forced vital capacity (FVC), and peak expiratory flow (PEF) are obtained from a single FVC manoeuvre. Results are displayed on a small liquid crystal display, but there is no graphical display. The performance of the Escor...

irrelevant. Chemistry and the relations between science, technology, and industry are well surveyed by Crosland and Cardwell respectively. Forbes's essay on mathematical cosmography is not a comprehensive account but the story (albeit interesting) of a few German cartographers. Compared with other recent collections of essays in the history of science, this volume parades no party line: witness...

MR compatible spirometer

Introduction: MR compatible spirometer is needed for (i) monitoring of anaesthetized patients and (ii) sequence synchronization and/or image reconstruction. Patient motion is likely to induce motion artifacts (ghosting) in image thus reducing its quality during MRI acquisitions. When breath-hold acquisitions are not possible, as for uncooperative children, an alternative technique is proposed, ...
