简要总结
The purpose of this pilot study is to evaluate the effect of high intensity non-invasive positive pressure ventilation (HINPPV) for stable, hypercapnic COPD patients. The investigators believe that HINPPV, used at least 6 hours nocturnally over three months, will benefit the stable hypercapnic COPD patient through a reduction in the daytime partial pressure of carbon dioxide in arterial blood (PaCO2) levels.
详细描述
The High Intensity Non-invasive Positive Pressure trial is a single arm interventional study. The purpose of this study is to evaluate the effect of High Intensity Non-invasive ventilation (HINPPV) in stable Chronic Obstructive Pulmonary patients with chronically elevated carbon dioxide levels. Participants will undergo various testing ( arterial blood gas (ABG), Pulmonary Function Test (PFTs), Polysomnography (PSGs), 6 minute walk tests)over a 3 month period to determine if this type of therapy will improve daytime carbon dioxide levels. The participants will also complete quality of life questionnaires to help ascertain improvements in their daily living activities.

研究组 & 干预措施
High Intensity Non Invasive Pos.Pressure
The High Intensity Non-invasive Pos.Pressure trial is a single arm interventional study. Hypercapnic COPD participants that meet eligibility criteria will receive high intensity non-invasive positive pressure ventilation (HINPPV) for 90 days. Participants will receive HINPPV via bilevel positive airway pressure (BiPAP Synchrony) if they require an inspiratory positive airway pressure (IPAP) less than or equal to 30 cmH2O (centimeters of water); or the Trilogy ventilator if they require an IPAP greater than 30 cmH2O.
干预措施: Bilevel positive airway pressure (BiPAP) (Device)
