Respiratory Therapist-Supported Home Noninvasive Ventilation in Stable Severe COPD Without Hypercapnia

Brief Summary

Chronic obstructive pulmonary disease (COPD) can cause persistent breathing problems, reduced exercise capacity, and repeated worsening of symptoms. Noninvasive ventilation (NIV) provides breathing support through a mask. Although NIV is commonly used in patients with respiratory failure, its role in patients with stable severe COPD without hypercapnia is less clear. The purpose of this study was to evaluate the feasibility of a respiratory therapist-supported home NIV program and to explore its potential clinical effects in adults with stable severe COPD without hypercapnia. Participants used a bilevel positive airway pressure device at home for at least 6 hours per day for 3 months. Respiratory therapists provided education and helped set up and adjust the device in collaboration with physicians according to each participant's comfort and breathing pattern. Participants were assessed before starting home NIV and after 1 and 3 months of treatment. Assessments included walking capacity, lung function, arterial blood gas measurements, breathing symptoms, and COPD-related health status. The study also evaluated participants' ability to tolerate and continue home NIV. The findings were intended to determine whether a respiratory therapist-supported home NIV program is practical and potentially beneficial for patients with stable severe COPD without hypercapnia.
