Measuring Lung Mechanics in Patients With COPD Using the REOM Handheld Portable Device
Measuring Lung Mechanics in Patients With Chronic Obstructive Pulmonary Disease (COPD) Using the Rapid Expiratory Occlusion Method (REOM) Handheld Portable Oscillometer: A Cross-Sectional Study.
Study Overview
Status
Conditions
Detailed Description
The primary objective of this cross-sectional study is to determine the concordance and agreement between the parameters obtained from the REOM, Reo1 and Reo2, and the conventional resistance parameters obtained by the tremoflo oscillometer device (R19 and R5, respectively) in adults with COPD confirmed by diagnostic pulmonary function testing (PFT).
The secondary objectives are:
- To investigate the discriminative capacity of the parameters obtained from the REOM to distinguish between 'mild' and 'very severe' COPD.
- To collect descriptive information on the participant user experience with the REOM.
- To determine concordance between the parameters obtained from the REOM and those obtained from the tremoflo oscillometry device with the 'standard' parameters obtained from each participant's standard Pulmonary Function Tests (PFT).
Hypothesis:
We hypothesize in the adult COPD patient population that the REOM parameter Reo1 and tremoflo device parameter R19 will correlate closely, and that the REOM parameter Reo2 and tremoflo device parameter R5 will correlate closely. We also hypothesize that the REOM, in particular, Reo2, will be able to distinguish between 'mild' and 'very severe' COPD, and that participants will report a positive user experience with the REOM.

Group / Cohort |
Intervention / Treatment |
---|---|
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 for which Health Canada approval (ITA Authorization) has been obtained for use in the present study.

Standard-of-care respiratory 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. |

What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Concordance (correlation)
Time Frame: Single-visit study: all tests performed at one single visit.
|
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
Time Frame: Single-visit study: all tests performed at one single visit.
|
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 Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Discriminative capacity
Time Frame: Single-visit study: all tests performed at one single visit.
|
The t-test (between 2 independent means) will be used to determine the discriminative capacity of the REOM to distinguish between 'mild' and 'very severe' COPD.
|
Single-visit study: all tests performed at one single visit.
|
Participant satisfaction and usability experience
Time Frame: Single-visit study: all tests performed at one single visit.
|
Each participant will complete a 'participant satisfaction questionnaire' as well as the validated System Usability Scale (SUS) for each test (REOM, standard oscillometry, pulmonary function test).
Data will be presented descriptively.
