NCT05913323

Brief Summary

The purpose the study is to determine the agreement between the information obtained about lung mechanics (lung function) from the Rapid Expiratory Occlusion Monitor (REOM) handheld portable device with that obtained by conventional oscillometry as well as by pulmonary function testing (PFT), in patients with both 'mild' as well as 'very severe' forms of chronic obstructive pulmonary disease (COPD). This study also intends to study the user experience with this handheld portable device.

Outcome Measures

Primary Outcomes (2)

  • Concordance (correlation)

    Correlation will be tested using the Spearman correlation coefficient (r) between REOM-obtained (Reo1 and Reo2) and tremoflo-obtained (R19 and R5) resistance measurements.

    Single-visit study: all tests performed at one single visit.

  • Agreement

    Agreement will be tested using the Bland-Altman test between REOM-obtained (Reo1 and Reo2) and tremoflo-obtained (R19 and R5) resistance measurements.

    Single-visit study: all tests performed at one single visit.

Secondary Outcomes (2)

  • Discriminative capacity

    Single-visit study: all tests performed at one single visit.

  • Participant satisfaction and usability experience

    Single-visit study: all tests performed at one single visit.

Study Arms (2)

COPD sub-group: GOLD 1 COPD

A secondary objective of the study is to investigate the discriminative capacity of the parameters obtained from the REOM to distinguish between 'mild' and 'very severe' COPD. Thus, there will be a 'mild' (GOLD 1) COPD sub-group.

Device: Rapid Expiratory Occlusion Monitor (REOM)Diagnostic Test: Standard oscillometryDiagnostic Test: Standard pulmonary function test

COPD sub-group: GOLD 4 COPD

A secondary objective of the study is to investigate the discriminative capacity of the parameters obtained from the REOM to distinguish between 'mild' and 'very severe' COPD. Thus, there will be a 'very severe' (GOLD 4) COPD sub-group.

Device: Rapid Expiratory Occlusion Monitor (REOM)Diagnostic Test: Standard oscillometryDiagnostic Test: Standard pulmonary function test

Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)
Sampling MethodNon-Probability Sample
Study Population

Patients with COPD at the Montreal Chest Institute (MCI) of the McGill University Health Centre (MUHC).

You may qualify if:

  • Males and females aged ≥40 with COPD, former/current smokers with a ≥10 pack-year smoking history.
  • Diagnosed with COPD by FEV1/FVC \< 0.7 using standard PFT post-bronchodilator testing, with either 'mild' ('GOLD 1': FEV1 ≥ 80% of predicted value) COPD or 'very severe' ('GOLD 4': FEV1 \< 30% of predicted value) COPD.
  • Ability to provide informed consent.

You may not qualify if:

  • No existing COPD diagnosis
  • History of co-morbid asthma
  • Current use of home oxygen
  • Any acute exacerbation of COPD (AECOPD) experienced within 4 weeks of participation in the study
  • Chronic respiratory infection
  • Any contraindication to respiratory testing
  • Inability to participate in reproducible measurements due to physical or cognitive barrier
