What is the purpose of this trial?

This trial explores how well Nasal High Flow (NHF) treatment aids individuals with Chronic Obstructive Pulmonary Disease (COPD) during a 6-Minute Walk Test, which measures the distance walked in six minutes. The study compares NHF to a lower flow of air to determine which more effectively reduces breathlessness. Participants should have COPD, be able to walk independently, and already use low-flow oxygen or no oxygen. As an unphased trial, this study provides a unique opportunity to contribute to understanding how NHF can enhance the quality of life for COPD patients.

Will I have to stop taking my current medications?

The trial information does not specify whether you need to stop taking your current medications. It's best to discuss this with the trial coordinators or your doctor.

What prior data suggests that nasal high flow is safe for COPD patients?

Research has shown that nasal high flow (NHF) therapy is generally well-tolerated by people with Chronic Obstructive Pulmonary Disease (COPD). Studies have found that NHF can improve exercise ability and quality of life, indicating its safety for patients with stable COPD. One study discovered that NHF reduced the need for inserting a breathing tube during COPD flare-ups, meaning it did not lead to more severe breathing issues compared to other treatments.

Another study found that using NHF at home for a year lowered the number of hospital visits and the time spent in the hospital for patients with severe COPD. This suggests that NHF is not only safe but also beneficial for long-term use.

In summary, NHF therapy has been shown to be safe for COPD patients, with studies reporting no increase in serious side effects like infections or death. It offers a promising option for those looking to manage their COPD symptoms more effectively. ^{1 2 3 4 5}

Why are researchers excited about this trial?

Researchers are excited about Nasal High Flow for COPD because it offers a new approach to delivering oxygen therapy. Unlike the standard low-flow oxygen therapy, which supplies oxygen at a lower rate, Nasal High Flow delivers it at a much higher rate of 70 liters per minute. This increased flow can improve the clearance of carbon dioxide and enhance breathing efficiency. Additionally, the high flow may offer more comfort and better outcomes for patients, which could be a significant improvement over traditional methods.

What evidence suggests that Nasal High Flow is effective for COPD?

This trial will compare the effectiveness of Nasal High Flow Cannula (HFNC) with Nasal Low Flow Cannula for COPD. Studies have shown that HFNC therapy can be very effective for people with COPD. Research indicates that HFNC works as well as non-invasive ventilation (NIV) in preventing the need for a breathing tube during a COPD flare-up. Patients using HFNC reported feeling more comfortable, and this therapy has proven valuable in treating severe breathing problems. Over a year, HFNC therapy significantly reduced both hospital visits and the frequency of worsening COPD symptoms. These positive results suggest that HFNC could help patients breathe easier and lead to fewer hospitalizations. ^{1 2 4 6 7}

What Are the Treatments Tested in This Trial?

Interventions

• Nasal High Flow

Trial Overview

The study is testing the effects of two types of oxygen delivery during exercise: high flow nasal cannula at 70 liters per minute and low flow. It measures how these affect exercise tolerance and breathlessness in COPD patients after walking for six minutes.

How Is the Trial Designed?

Group I: Nasal High Flow Cannula Experimental Treatment 2 Interventions

Nasal High Flow cannula at 70 liters per minute for 30 minutes. Given that this is a cross-over study, participants on this arm will be then crossed over to Nasal Low Flow Cannula at less than or equal to 4 liters per minute with supplemental oxygen for 30 minutes

Group II: Nasal Low Flow Cannula Active Control 2 Interventions

Low Flow Nasal Cannula at less than or equal to 4 liters per minute with supplemental oxygen at patient's baseline for 30 minutes. Given that this is a cross-over study, participants on this arm will be then crossed over to High Flow Cannula at 70 liters per minute for 30 minutes

Published Research Related to This Trial

High flow nasal cannula (HFNC) is an effective and safe treatment for adults with acute hypercapnic respiratory failure (AHRF), showing comparable outcomes in intubation rates, mortality, and arterial blood gas improvement when compared to conventional oxygen treatment (COT) and non-invasive ventilation (NIV).

HFNC offers greater comfort and fewer adverse events than NIV, and it can significantly reduce heart rate, respiratory rate, and hospital stay length, while also decreasing the need for NIV in patients with compensated hypercapnia.

A study of 321 Japanese adults using high-flow nasal cannula (HFNC) oxygen therapy showed significant improvements in respiratory parameters, including oxygen levels and respiratory rate, indicating its efficacy in treating acute hypoxemic respiratory failure and other conditions.

HFNC was primarily used in intensive care and general wards, with a median duration of 4 days, and about two-thirds of patients survived to discharge, highlighting its potential effectiveness in real-world clinical settings.

High-flow nasal cannula (HFNC) therapy significantly improved dyspnea, breathing frequency, and oxygen saturation in 90 out of 111 patients treated outside the ICU, indicating its efficacy in non-ICU settings.

Despite the benefits observed, the study reported a high overall mortality rate of 50%, suggesting that HFNC may often be used in a palliative context, particularly among patients with do not resuscitate (DNR) orders.

Humidified high-flow nasal cannula oxygen therapy (HFNC) significantly improves respiratory function in stable COPD patients, as evidenced by higher FEV1, FEV1%, and FEV1/FVC values compared to conventional oxygen therapy (COT).

HFNC also enhances the quality of life and reduces adverse reactions in patients, with better blood gas analysis results (higher pH and PaO2, lower PaCO2) and improved exercise capacity, indicating its safety and efficacy.

In a study of 337 patients with acute COPD exacerbation, high-flow nasal cannula (HFNC) did not significantly reduce the need for intubation compared to conventional oxygen therapy, indicating similar efficacy in this regard.

HFNC was associated with a longer hospital stay and higher costs compared to conventional oxygen therapy, suggesting that while it may not improve clinical outcomes, it could lead to increased resource use.

High-Flow Nasal Cannula (HFNC) therapy offers several physiological benefits for COPD patients, including improved gas exchange, enhanced comfort, and a more stable oxygen delivery compared to conventional oxygen therapy.

In stable COPD patients, HFNC has been shown to improve quality of life and reduce dyspnea, while in exacerbated cases, it may serve as a viable alternative to non-invasive ventilation and conventional oxygen therapy, although more research is needed to confirm its superiority.
