Assessment 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...
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 کاملValidation of the portable Air-Smart Spirometer
BACKGROUND The Air-Smart Spirometer is the first portable device accepted by the European Community (EC) that performs spirometric measurements by a turbine mechanism and displays the results on a smartphone or a tablet. METHODS In this multicenter, descriptive and cross-sectional prospective study carried out in 2 hospital centers, we compare FEV1, FVC, FEV1/FVC ratio measured with the Air S...
متن کاملFour-year calibration stability of the EasyOne portable spirometer.
BACKGROUND Clinical practice guidelines recommend daily spirometer calibration checks and weekly linearity checks. The long-term stability of the volume and flow accuracy of a specific model of spirometer should be carefully characterized before modification of the frequency of calibration checks is considered for that model of spirometer. METHODS The EasyOne ultrasonic flow-sensing spiromete...
متن کاملAssessment of accuracy and applicability of a portable electronic diary card spirometer for asthma treatment.
A pocked-sized turbine flowmeter and spirometer device, integrated with an electronic diary card (EDC-spirometer, Micro Medical, U.K.), was tested with a mechanical calibrator, in an outpatient clinic and in the home situation. A screen pneumotachometer was used as flow and volume reference. Ten devices were tested; interdevice variability was small with a mean variation coefficient of 1.1% for...
