Oscillometry (also known as the forced oscillation technique) measures the mechanical properties of the respiratory system (upper and intrathoracic airways, lung tissue and chest wall) during quiet tidal breathing, by the application of an oscillating pressure signal (input or forcing signal), most commonly at the mouth. With increased clinical and research use, it is critical that all technical details of the hardware design, signal processing and analyses, and testing protocols are transparent and clearly reported to allow standardisation, comparison and replication of clinical and research studies. Because of this need, an update of the 2003 European Respiratory Society (ERS) technical standards document was produced by an ERS task force of experts who are active in clinical oscillometry research.The aim of the task force was to provide technical recommendations regarding oscillometry measurement including hardware, software, testing protocols and quality control.The main changes in this update, compared with the 2003 ERS task force document are 1) new quality control procedures which reflect use of “within-breath” analysis, and methods of handling artefacts; 2) recommendation to disclose signal processing, quality control, artefact handling and breathing protocols (e.g. number and duration of acquisitions) in reports and publications to allow comparability and replication between devices and laboratories; 3) a summary review of new data to support threshold values for bronchodilator and bronchial challenge tests; and 4) updated list of predicted impedance values in adults and children.

Breath Tests

Breath tests cover the fraction of nitric oxide in expired gas (FENO), volatile organic compounds (VOCs), variables in exhaled breath condensate (EBC) and other measurements. For EBC and for FENO, official recommendations for standardised procedures are more than 10 years old and there is none for exhaled VOCs and particles. The aim of this document is to provide technical standards and recommendations for sample collection and analytic approaches and to highlight future research priorities in the field. For EBC and FENO, new developments and advances in technology have been evaluated in the current document. This report is not intended to provide clinical guidance on disease diagnosis and management.Clinicians and researchers with expertise in exhaled biomarkers were invited to participate. Published studies regarding methodology of breath tests were selected, discussed and evaluated in a consensus-based manner by the Task Force members.Recommendations for standardisation of sampling, analysing and reporting of data and suggestions for research to cover gaps in the evidence have been created and summarised.Application of breath biomarker measurement in a standardised manner will provide comparable results, thereby facilitating the potential use of these biomarkers in clinical practice.

Joint Task Force

Spirometry is the basic method for pulmonary function evaluating but it is very dependent on the quality of performance. Currently, specialists in lung function diagnostics rely on the 2005 technical standards of spirometry, jointly developed by the American thoracic Society (ATS) and the European Respiratory Society (ERS), adapted for our country by the Russian Respiratory Society in 2013. New technical capabilities and research studies have shown the need to improve approaches to ensuring the measurements quality. A joint task force with experience in conducting and analyzing pulmonary functional tests assigned by the ATS and ERS has significantly updated international standards to ensure quality laboratory practice. The article discusses the standards update by the 2019 consensus, as well as the new added factors that were not previously mentioned. New standards are needed for manufacturers, clinicians, functional diagnostics specialists and researchers in order to increase the accuracy of spirometric measurements and reduce the negative impact on the patient.

Clear Information

The American Thoracic Society and European Respiratory Society commissioned a task force to update the technical standards for spirometry testing with the aim of increasing the accuracy, precision, and quality of spirometry measurements and improving the patient experience.To inform the task force with patient experiences, European Lung Foundation, in collaboration with the task force, conducted an online survey in 10 languages between August and September 2018.There were 1760 respondents from 52 countries. The majority were adults (97.1%) and the most common reasons for spirometry referral were diagnosis (35.5%) and management of an ongoing condition (60.9%). 53.2% reported regularly using inhalers.Respondents were very experienced with spirometry: 89.9% completed more than one test; 48% completed 10 or more tests. However, most reported not knowing what FEV1 means (59.4%) and only 39.6% knew their most recent FEV1; the exception was respondents with cystic fibrosis (CF) who reported much greater knowledge.Respondents rated as moderately or seriously problematic: being told to keep blowing when they felt nothing is coming out (31.4%), coughing (30.4%), tiredness (26.3%) and concern about shortness of breath (20.1%).Overall, respondents found spirometry to be acceptable, however an important minority (17%) find it difficult. Patients want clear information before, during and after the test, including information on stopping medications. Operators have an important role in increasing the ease of patients, and changes to the testing environment can increase patient comfort. Patients want access to their results and want to understand how they relate to their individual health.

Genetic Burden

Due to its high association with Raynaud’s phenomenon systemic sclerosis (SSc) is probably the most common connective tissue disease seen by vascular specialists. In part 1 of our systematic overview we summarize classification concepts of scleroderma disorders, the epidemiologic and genetic burden, the complex pathophysiologic background, and the clinical features and the stage-dependent capillary microscopic features of SSc. Furthermore, we address the diagnostic recommendations propagated by the German Network for Systemic Sclerosis and the Task Force for Diagnosis and Treatment of Pulmonary Hypertension of the European Society of Cardiology, the European Respiratory Society, and the International Society of Heart and Lung Transplantation.

Abstract In wafer fabrication (Fab), Fluorine (F) based gases are used for Al bondpad opening process. Thus, even on a regular Al bondpad, there exists a low level of F contamination. However, the F level has to be controlled at a lower level. If the F level is higher than the control/spec limits, it could cause F-induced corrosion and Al-F defects, resulting in pad discoloration and NSOP problems. In our previous studies [1-5], the theories, characteristics, chemical and physical failure mechanisms and the root causes of the F-induced corrosion and Al-F defects on Al bondpads have been studied. In this paper, we further study F-induced corrosion and propose to establish an Auger monitoring system so as to monitor the F contamination level on Al bondpads in wafer fabrication. Auger monitoring frequency, sample preparation, wafer life, Auger analysis points, control/spec limits and OOC/OOS quality control procedures are also discussed.

The Impact

Obstructive sleep apnoea (OSA) is highly prevalent and is a recognised risk factor for motor vehicle accidents (MVA). Effective treatment with continuous positive airway pressure (CPAP) has been associated with a normalisation of this increased accident risk. Thus, many jurisdictions have introduced regulations restricting the ability of OSA patients from driving until effectively treated. However, uncertainty prevails regarding the relative importance of OSA severity determined by the apnoea-hypopnoea frequency per hour and the degree of sleepiness in determining accident risk. Furthermore, the identification of subjects at risk for OSA and/or accident risk remains elusive. The introduction of official European regulations regarding fitness to drive prompted the European Respiratory Society to establish a Task Force to address the topic of sleep apnoea, sleepiness and driving with a view to providing an overview to clinicians involved in treating patients with the disorder. The present report evaluates the epidemiology of MVA in patients with OSA, the mechanisms involved in this association, the role of screening questionnaires, driving simulators and other techniques to evaluate sleepiness and/or impaired vigilance, the impact of treatment on MVA risk in affected drivers, and highlights the evidence gaps regarding the identification of OSA patients at risk for MVA.
