Technical and Functional Assessment of 10 Office Spirometers: Comment

At variance with standard spirometers, the majority of the office spirometers were not calibrated during the study (Table 1). This may seen somewhat surprising in a laboratory study, but we wanted to respect the instructions of the vendors/manufacturers also in … Continue reading

Technical and Functional Assessment of 10 Office Spirometers: Recommendation

We did not compare the quality and the cost of the mouthpieces, nor the facility of disinfecting the parts in contact with the exhaled air. We do not have any information on the long-term solidity of the devices, nor on … Continue reading

Technical and Functional Assessment of 10 Office Spirometers: Conclusion

We devised a new questionnaire about the user friendliness of office spirometers. The results of this small and informative survey suggest large similarities among the majority of the spirometers. Almost all of them have an interface with a personal computer, … Continue reading

Technical and Functional Assessment of 10 Office Spirometers: Discussion

The tests done with the computer-controlled mechanical syringe indicate that the spirometers working under ideal laboratory conditions, at least at ambient conditions, are reliable, but they do not guarantee that the same performances will be obtained in real-life conditions, as … Continue reading

Technical and Functional Assessment of 10 Office Spirometers: Research

The use of the 24 ATS standard waveforms for FVC and FEV1 is recommended, but the recent ATS/ERS statement does not require that these tests must be performed by an independent laboratory, such as the laboratory at LDS Hospital for … Continue reading

Technical and Functional Assessment of 10 Office Spirometers: User-Friendliness Assessment

Some office spirometers showed an apparent good agreement with the standard spirometers (low bias), but the visual inspection of the Bland and Altman plot revealed a proportional difference. In other words, there was a significant relationship between the mean difference … Continue reading

Technical and Functional Assessment of 10 Office Spirometers: Results

A total of 399 different subjects (age range, 25 to 87 years; mean ± SD, 61.2 ± 14.6 years; 128 women) were studied in the three centers. The distribution of the 300 COPD patients according to the GOLD classification was … Continue reading

Technical and Functional Assessment of 10 Office Spirometers: Assessment of User Friendliness

We developed a novel questionnaire to assess the user friendliness of office spirometers (to view Tables A and B in the on-line supplementary data, go to www.chestnet.org). The questionnaire completed by the three GPs covered the following: general properties and … Continue reading

Technical and Functional Assessment of 10 Office Spirometers: Setting

The ETs were asked to perform PFTs in the two other centers to verify interchangeability of the results. There was no significant difference between centers in absolute values and reproducibility (p > 0.05, by one-way analysis of variance; Fig 1). … Continue reading

Technical and Functional Assessment of 10 Office Spirometers: Setting

The study was divided into an in-laboratory study and an assessment of user friendliness of the office spirometers. The in-laboratory study was performed in the pulmonary function laboratories of three academic hospitals in Belgium. For the user-friendliness assessment, the office … Continue reading
