Mindful Breathing Awareness Through Pursed-Lip Breathing Training

Study Overview
=================
Brief Summary
-----------------
To establish the feasibility of a tool that monitors and motivates people with COPD to complete training in mindful pursed-lip breathing to enhance pulmonary rehabilitation at home.

Detailed Description
-----------------
For this pilot study patients who meet the conventional criteria for pulmonary rehabilitation at their clinical appointments will be recruited and scheduled to return for the study. After completing the informed consent, patients will be taught how to don and doff the pulse oximeter, the source of the heart rate and oxygen signals. Patients will participate in a demonstration on how to perform the intervention. Recruitment will continue until five patients have completed the pilot in a clinic setting. If necessary, the prototype will be modified and testing resumed. Once the prototype system has met the criteria for success in the clinic, five of patients will be asked to use the prototype at the clinic and to take it home for a week and perform the intervention at least five times.

Design Details

Primary Purpose: Device Feasibility
Intervention Model: Single Group Assignment
Interventional Model Description: pilot study
Masking: None (Open Label)


Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: Breathing Awareness<br>In the clinic, once patients are proficient with the proposed tool, they will (1) independently don the pulse oximeter, (2) use the prototype to perform the mindful breathing intervention. The whole session will last no longer than 60 minutes with 30 minutes for the consent and demonstrations, two minutes to don the study devices, 15 minutes to practice mindful breathing, and two minutes to doff the study devices. The mindful breathing portion will be divided into three sessions. Each session will last three minutes and display a different presentation of Heart Rate Coherence biofeedback. At home, after completing the in-clinic study, five patients will take the mindful breathing tool home for a week to practice pursed-lip breathing at least five times. They will don the study devices, perform the intervention, and doff study devices. | Other: Breathing Awareness<br>* Participants will use a pulse-oximeter and biofeedback app to guide them through pursed-lip breathing training.<br>|
