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

Are You a Good Fit for This Trial?

This trial is for adults aged 30 or older with certain lung diseases like COPD, ILD, or PH who need oxygen therapy at rest. They must have a history of stable heart rate and blood pressure, not be pregnant or breastfeeding, and haven't had recent cardiovascular issues.

Inclusion Criteria

My blood oxygen level is above 80% without extra oxygen.

You have had a pulmonary function test in the last three months.

I am 30 years old or older.

Exclusion Criteria

I have had recent heart or stroke issues.

Pregnancy or lactation

Treatment with another investigational drug or other intervention within three months

Timeline for a Trial Participant

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

What Are the Treatments Tested in This Trial?

Interventions

• Nasal Delivery of High-Flow Air and Oxygen Therapy
• Nasal Delivery of Oxygen Therapy

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.

How Is the Trial Designed?

Group I: Baseline followed by intervention 2f Experimental Treatment 2 Interventions

Subjects perform baseline titration with oxygen only first. Subjects are then titrated with six different delivery methods. The subjects will be first delivered Out-of-Phase pulsed high-flow air and oxygen (order of high-flow air flow rate: 25 L/min, 20 L/min, 15 L/min) and then Continuous high-flow air with pulsed oxygen (order of high-flow air flow rate: 25 L/min, 20 L/min, 15 L/min).

Group II: Baseline followed by intervention 2e Experimental Treatment 2 Interventions

Subjects perform baseline titration with oxygen only first. Subjects are then titrated with six different delivery methods. The subjects will be first delivered Out-of-Phase pulsed high-flow air and oxygen (order of high-flow air flow rate: 25 L/min, 15 L/min, 20 L/min) and then Continuous high-flow air with pulsed oxygen (order of high-flow air flow rate: 25 L/min, 15 L/min, 20 L/min).
