Trial Summary
What is the purpose of this trial?
This study is meant to compare the amount of oxygen required for hypoxemia relief between current standard of care (oxygen only) and oxygen with the addition of high flow air for Chronic Obstructive Pulmonary Disease (COPD), Interstitial Lung Disease (ILD), and Pulmonary Hypertension (PH) patients during rest. Subjects will be titrated from 0 L/min until they maintain 95% SpO2 for each of the following delivery methods:
1. Pulses of pure oxygen (control)
2. Constant high flow air with pulses of pure oxygen
3. Out of phase pulses of high flow air and pure oxygen

Timeline
Screening
Participants are screened for eligibility to participate in the trial
1-2 weeks
Baseline Titration
Participants perform baseline titration with oxygen only to determine the required oxygen flow rate to maintain 95% SpO2.
Approximately 15 minutes
1 visit (in-person)
Intervention
Participants are titrated with six different delivery methods, including Out-of-Phase pulsed high-flow air and oxygen, and Continuous high-flow air with pulsed oxygen.
4-5 hours
1 visit (in-person)
Follow-up
Participants are monitored for safety and effectiveness after treatment
1-2 weeks

Trial Overview The study compares standard oxygen therapy to two new methods: one combines high-flow air with oxygen, and the other alternates between them. The goal is to see which method best maintains an oxygen saturation level of 95% during rest.
