Preserved ratio impaired spirometry is associated with small airway dysfunction and reduced total lung capacity

Respiratory Research, 2022
Background: Preserved ratio impaired spirometry (PRISm) refers to decreased forced expiratory volume in 1 s (FEV 1 ) in the setting of preserved ratio.

Deep learning using multilayer perception improves the diagnostic acumen of spirometry: a single-centre Canadian study

BMJ Open Respiratory Research, 2022
Rationale Spirometry and plethysmography are the gold standard pulmonary function tests (PFT) for diagnosis and management of lung disease. Due to the inaccessibility of plethysmography, spirometry is often used alone but this leads to missed or ...

Spirometry parameters used to define small airways obstruction in population-based studies: systematic review

Respiratory Research, 2022
Background The assessment of small airways obstruction (SAO) using spirometry is practiced in population-based studies. However, it is not clear what are the most used parameters and cut-offs to define abnormal results.

Mechanism of spirometry associated gastro-esophageal reflux in individuals undergoing esophageal assessment.

PLoS ONE, 2023
Persistent variability observed during spirometry, even when technical and personal factors are controlled, has prompted interest in uncovering its underlying mechanisms.

Restricted spirometry and cardiometabolic comorbidities: results from the international population based BOLD study

Respiratory Research, 2022
Background Whether restricted spirometry, i.e. low Forced Vital Capacity (FVC), predicts chronic cardiometabolic disease is not definitely known. In this international population-based study, we assessed the relationship between restricted spirometry and

Prevalence and effects of gastro-oesophageal reflux during spirometry in subjects undergoing reflux assessment.

PLoS ONE, 2020
Variability during spirometry can persist despite control of technical and personal factors. We postulate spirometry induces gastro-oesophageal reflux (GOR), which may cause variability and affect results of spirometry.

HERMES Spirometry: the European Spirometry Driving Licence [PDF]

Breathe, 2011
Spirometry testing is the most widely practiced, most common and adaptable of all lung function tests and spirometers are used as a key instrument in the diagnosis of patients with respiratory disease [1]. As a leading cause of death worldwide responsible for some 9.4 million deaths [2], and further increases predicted by 2020, the management of lung ...

The Impact of an Electronic Health Record Intervention on Spirometry Completion in Patients with Chronic Obstructive Pulmonary Disease

COPD, 2022
Spirometry is necessary to diagnose chronic obstructive pulmonary disease (COPD), yet a large proportion of patients are diagnosed and treated without having received testing.

Standardization of Spirometry 2019 Update. An Official American Thoracic Society and European Respiratory Society Technical Statement

American Journal of Respiratory and Critical Care Medicine, 2019
Background: Spirometry is the most common pulmonary function test. It is widely used in the assessment of lung function to provide objective information used in the diagnosis of lung diseases and monitoring lung health.
