Study Summary

Expiratory Flow Limitation (EFL) occurs when the airways become compressed, which usually results when the pressure outside the airway exceeds the pressure inside the airway. EFL can be detected using the Forced Oscillation Technique (FOT), which has been incorporated into a new screening feature in the Philips Respironics BiPAP Ventilator overall platform (Vector Non-Invasive (NIV) device). In this study, the Vector device will be used in a cross-sectional non-randomized epidemiology study to assess the prevalence and severity of expiratory flow limitation in a community COPD population. The study will also investigate how the presence of EFL may correlate with other physiological biomarker endpoints in the COPD patient. Participants will include 100 male and females with a diagnosis of COPD between the ages of 40 and 80. During the one-visit study, participants will undergo an EFL screening using the Vector device. If EFL is not detected during the screening after 5 minutes, the participant will not continue. If EFL is detected by the device, the participant will continue to wear it while it measures the level of therapy that is needed to eliminate EFL. Twenty minutes of pressure therapy will then be provided and the final Expiratory Positive Airway Pressure (EPAP) that is determined to abolish the participants EFL will be recorded. Participant characteristics (e.g. health history, behaviors, anthropometric, vitals, etc.) will be also be collected via questionnaires, medical record review, and physical exam. Future benefits of the study will be to gain a better understanding of the Vector screening feature and the characteristics of patients who present with varying degrees of EFL severity.

Primary Outcome

The overall prevalence of EFL will be determined. This is defined as the percentage of participants exhibiting a DeltaXRS value greater than or equal to 2.8 using the Vector EFL device while supine. For purposes of this trial, overall prevalence includes indeterminate EFL and EFL.
