Millimetre‐wave radar‐based spirometry for the preliminary diagnosis of chronic obstructive pulmonary disease

IET Radar, Sonar & Navigation, 2023
Chronic respiratory diseases, especially chronic obstructive pulmonary disease (COPD), have high morbidity and mortality worldwide. Spirometry is regarded as the gold standard for the diagnosis of COPD. However, conventional spirometry requires expensive

Reduced exercise capacity is associated with left ventricular systolic dysfunction in long‐term survivors of allogeneic hematopoietic stem‐cell transplantation

Journal of Clinical Ultrasound, Volume 51, Issue 1, Page 5-15, January 2023., 2023
Exercise intolerance is a common complication in long‐term survivors of allogeneic hematopoietic stem‐cell transplantation. In this study, we found reduced oxygen uptake (VO2peak) by cardio‐pulmonary exercise tests to be associated with left ventricular systolic dysfunction by echocardiography.

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.

Home spirometry in patients with idiopathic pulmonary fibrosis: data from the INMARK trial

European Respiratory Journal, 2021
Background Data from the INMARK trial were used to investigate the feasibility and validity of home spirometry as a measure of lung function decline in patients with idiopathic pulmonary fibrosis (IPF).

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.

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 ...

Exploring the 175-year history of spirometry and the vital lessons it can teach us today

European Respiratory Review, 2021
175 years have elapsed since John Hutchinson introduced the world to his version of an apparatus that had been in development for nearly two centuries, the spirometer.

Different Risks of Mortality and Longitudinal Transition Trajectories in New Potential Subtypes of the Preserved Ratio Impaired Spirometry: Evidence From the English Longitudinal Study of Aging

Frontiers in Medicine, 2021
Background: Preserved ratio impaired spirometry (PRISm), characterized by the decreased forced expiratory volume in 1 s (FEV1) and forced vital capacity (FVC) with a preserved FEV1/FVC ratio, is highly prevalent and heterogeneous.

How Accurate Is the Diagnosis of “Chronic Obstructive Pulmonary Disease” in Patients Hospitalized with an Acute Exacerbation?

Medicina, 2023
Rationale: COPD diagnosis requires relevant symptoms and an FEV1/FVC ratio of 0.7), and those who have never performed spirometry. Results: A total of 1138 patients with a recorded diagnosis of COPD were identified of which 233 patients were included in
