NCT04350970

Brief Summary

Patients with COPD are often unable to sustain a sufficient workload during exercise. The use of external strategies to improve exercise tolerance, such as non-invasive ventilation (NIV) and high-flow nasal therapy (HFNT) have been used. The objective was to evaluate and compare the acute effects of HFNT and NIV during exercise on cardiorespiratory parameters, dyspnea, exercise tolerance and comfort in patients with moderate to severe COPD.

Outcome Measures

Primary Outcomes (2)

  • Exercise dinamic hyperinflation

    To determine the dinamic hyperinflation during exercise test with 3-different situations , Control, NIV and HFNT. During all testes the dinamic hyperinflation will be measured by inspiratory capacity (at rest and at the end o exercise test) and will be demonstrated as porcentage os maximum.

    one week after all tests

  • Exercise Tolerance

    To determine the exercise tolerance with 3-different situations , Control, NIV and HFNT. Time of exercise test will be measured to determine which test could be the best for COPD patients. In additional, the workload will (treadmill inclination and speed) be check to show which intervention has the better response.

    one week after all tests

Secondary Outcomes (1)

  • Dyspnea

    one week after all tests

Study Arms (3)

Control

ACTIVE COMPARATOR

The cardiopulmonary exercise test was performed with patient breathing room air.

Other: Control

NIV

ACTIVE COMPARATOR

The cardiopulmonary exercise test was performed with non-invasive ventilation during the test.

Other: Non-invasive ventilation

HFNT

ACTIVE COMPARATOR

The cardiopulmonary exercise test was performed with a High flow nasal therapy during the test.

Other: High flow nasal therapy

Interventions

All patients underwent two cardiopulmonary exercises with constant-load at 90% of the peak workload. The high flow nasal therapy was used during all exercise test.

HFNT

All patients underwent two cardiopulmonary exercises with constant-load at 90% of the peak workload. The NIV was used during all exercise test.

NIV
ControlOTHER

All patients underwent two cardiopulmonary exercises with constant-load at 90% of the peak workload. The control test was performed with no additional therapy.
