Respiratory Strategies in COPD Patients With Persistent Hypercapnia Following Exacerbation
Recruiting now · Not applicable
Conditions studied: COPD, Hypercapnia, Exacerbation Copd
In brief
This multicenter, cross-over study aims to investigate the effects of two different respiratory strategies, the use of high flow nasal cannula (NHF) and the use of home mechanic ventilation (HMV), both associated with standard oxygen therapy, in patients with COPD and persistent hypercapnia following a severe acute exacerbation. The purpose is to evaluate whether the clinical benefits, in terms of reduction in PaCO2 levels, resulting from the use of NHF are non-inferior to those obtained from the use of HMV. Partecipants will be randomized at 1:1 ratio into two groups: group 1: will start the respiratory strategy under study (NHF + standard oxygen therapy) as first treatment group 2 will start the control respiratory strategy (HMV + standard oxygen therapy) as first treatment. The study has a crossover design: each patient will undergo treatment with the two different respiratory strategies, NHF and HMV, each lasting for 3 months

You may qualify if…
- Age ≥18 years
- Acquisition of informed consent form
- Patients with COPD
- Persistent hypercapnia (PaCO2 >53 mmHg) 2-4 weeks after an acute hypercapnic exacerbation of COPD requiring NIV.
- pH value >7.35.
- Chronic hypoxemia (PaO2 <55mmHg or <60mmHg if at least one of the following criteria is present: polycythemia, pulmonary hypertension or Chronic Pulmonary Heart Disease, >30% of sleep time with SpO2 < 90% measured with a pulse oximeter)
