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...
متن کاملA comparison of a new transtelephonic portable spirometer with a laboratory spirometer.
The Spirophone is a new, portable transtelephonic spirometer which records the slow and the forced expiratory vital capacity tests. Data can be transmitted via the telephone to a remote receiving centre, where a volume-time curve and the flow-volume curve are displayed on screen in real time. The aim of this study was to compare the newly developed transtelephonic spirometer, with a laboratory ...
متن کاملMR 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, ...
متن کاملClinical evaluation of a new electronic spirometer.
An electronic spirometer which utllizee a thermistor end an linearizing circuit, was evaluated. When compared to a Collins 13.5 liter water seal spirometer, 60 test results from 30 patienls revealed no clinically significant difference in forced vital capacity (FVC), forced expiratory volume in one second (FEVih or maximum voluntary ventilation (MVV). The device was found durable Pnd highly use...
متن کاملAssessment of a new transtelephonic portable spirometer.
BACKGROUND A new portable spirometer, the Spirophone, has been developed that records a subject's blow and can then transmit all the data by telephone to a receiving centre for analysis and comment. Tests of this device were undertaken to determine its accuracy and reliability. METHODS The performance of the Spirophone was tested using computer generated wave forms, by delivering blows from c...
