The Application and Analysis of HHHFNC in Walking Test of Pulmonary Rehabilitation

Overview

The aim of this study is to investigate the use heated humidified high-flow nasal cannula (HHHFNC) in pulmonary rehabilitation and analysis of cardiopulmonary parameters in adult patients.

Objectives： The aim of this study is to investigate the use heated humidified high-flow nasal cannula (HHHFNC) in pulmonary rehabilitation and analysis of cardiopulmonary parameters in adult patients. Background： Recently, HHHFNC has been used in both adult and neonates with post-extubation respiratory support. Studies indicate that HHHFNC has similar efficacy compared to non-invasive positive pressure ventilation and superior than conventional oxygen therapy. Six-minute walking test (6-MWT) is a standardized laboratory tests to evaluate the endurance capacity in adult patients. It helps clinician to modify the treatment plan. Cirio, et at. has been shown HHHFNC may improve the exercise performance in severe chronic obstructive pulmonary disease (COPD) patients with ventilatory limitation. Study Design： This is a prospective clinical trial in a pulmonary rehabilitation out-patient department (2018.08.01-2019.07.31).。 Methods： Patents with COPD who done pulmonary function test will enroll to this study. Left-side heart failure, COPD acute-exacerbation (AE) within 3 months, diagnosed neuromuscular disease, and unable to perform 6-MWT will be exclude. The data will be collected for and analyzed. Effect： Investigators expect the exercise performance; cardiopulmonary function will be improve under HHHFNC support. We hope the application of HHHFNC in adult patient with pulmonary rehabilitation could enhance the quality of life. Key words： chronic obstructive pulmonary disease; heated humidified high-flow nasal cannula; pulmonary rehabilitation, six-minute walking test.
