BACKGROUND Objective measurement of lung function is considered essential in the management of patients with asthma and COPD. Many primary care practitioners lack the means necessary to obtain these measurements conveniently. To meet this need, electronic spirometers, offering portability, ease of operation, and timesaving readout options have been introduced. We compared the accuracy of a typical pneumotachograph-based device with a conventional volume displacement spirometer. METHODS We…

The accuracy of a handheld “disposable pneumotachograph device” in the spirometric diagnosis of airway obstruction in a Chinese population
TLDR
A disposable handheld spirometry device is capable of accurately identifying and quantifying airway obstruction in patients deemed to be at risk, however, caution should be exercised and all available brands should be tested.
Accuracy of Office Spirometry Performed by Trained Primary-Care Physicians Using the MIR Spirobank Hand-Held Spirometer
TLDR
The Spirobank device seems to be appropriate for research purposes if the standardized protocol is used correctly and the acceptability criteria are respected, and high correlations were found for the pulmonary function parameters.
Lung Function Monitoring; A Randomized Agreement Study
TLDR
Oxycon Pro obtained most frequently values of the lung function variables with highest precision as indicated by the coefficients of repeatability (CR), followed by MasterScreen, SensorMedics and SpiroUSB.
Accuracy and Precision of Desktop Spirometers in General Practices
TLDR
On average, desktop spirometers in general practices slightly overestimated FEV1 and FVC values, but some devices showed substantial deviations, and general practices should pay more attention to the calibration of their spirometer.
Comparison of a new desktop spirometer (Spirospec) with a laboratory spirometer in a respiratory out-patient clinic.
TLDR
The Spirospec is comparable to the Masterlab 4.0, with high accuracy for FEV(1) and forced vital capacity and clinically acceptable differences in the measured flow variables.
Pulmonary function electronic monitoring devices: a randomized agreement study.
TLDR
These low-cost and easy-to-use electronic monitoring devices showed a very good reproducibility and were in agreement with the pneumotachograph, and seem adequate for both screening and monitoring.
Considerations in the use of different spirometers in epidemiological studies
TLDR
Comparisons in the use of different spirometers in epidemiological studies are explored by comparing forced expiratory volume in 1 (FEV1) and forced vital capacity (FVC) measurements between the Masterscreen pneumotachograph and EasyOne spirometers.
Accuracy and Quality of Spirometry in Primary Care Offices.
TLDR
The results raise concerns regarding the utility of spirometry obtained in primary care offices without greater attention to quality assurance and training.
Testing Spirometers: Are the Standard Curves of the American Thoracic Society Sufficient?
TLDR
The global quality of most spirometers makes them acceptable for the detection of pulmonary diseases, however, they demonstrated accuracy issues not shown by the standard testing procedure.
Effects of equipment and technique on peak flow measurements
TLDR
Peak flow measurements are affected by the instruction given and by the device and Peak Flow scale used, and patient management decisions should not be based on PEF measurement made on different instruments.

Evaluation of a new electronic spirometer: the vitalograph "Escort" spirometer.
TLDR
The Escort spirometer compares extremely well with a wedge bellows spirometer for measurement of FEV1 and FVC, whilst yielding results of PEF from an FVC manoeuvre which are comparable to those obtained from a Wright meter.
Evaluation of "electronic" spirometers.
TLDR
Evaluated Portable electronic spirometers, often with direct readout, are now replacing conventional water or bellows spirometers for office, clinic and bedside use, with serious inadequacies observed.
Performance evaluation of contemporary spirometers.
TLDR
Simple testing of spirometers with a 3 L calibrating syringe for validation purposes was inadequate to assess spirometer performance when compared to dynamic waveform testing.
Evaluating commercially available spirometers.
TLDR
It is concluded that most available spirometers can faithfully record forced spirograms and that if a spirometer meets the ATS requirements, it makes no difference on which device the spirogram is recorded.
Reference spirometric values using techniques and equipment that meet ATS recommendations.
TLDR
This study produced predicted values for forced vital capacity and forced expiratory volume in one second that were almost identical to those predicted by Morris and associates when the data from their study were modified to be compatible with the back extrapolation technique recommended by the ATS.
Changes in the normal maximal expiratory flow-volume curve with growth and aging.
TLDR
Improved prediction equations for each sex by age group for 5 spirometric and flow-volume variables are derived and "Normal" limits are proposed that take into consideration the between-subject variability and non-Gaussian distribution of the various measurements.
Physician perceptions and management of COPD.
TLDR
Primary care practitioners have a low index of suspicion for obstructive airway disease, markedly underutilized spirometry as a screening tool, consider beta 2-agonists first-line therapy for COPD and asthma, and despite considering COPDand asthma different disease processes, choose similar medications for each disorder.
BTPS correction for ceramic flow sensor.
TLDR
Use of exit air temperature provides a means of estimating a dynamic BTPS correction factor, and this technique may be sufficient to provide an FEV1 accuracy of less than +/- 3 percent for exit air temperatures from 5 degrees to 28 degrees C.

TLDR
If airways obstruction is present, inhaled quaternary anticholinergic bronchodilators or inhaled beta 2 agonists or both may be of benefit, the former agents showing fewer side effects and often greater efficacy in elderly patients, although proof of efficacy is lacking.
