High Intensity Non-Invasive Positive Pressure Ventilation (HINPPV)
High Intensity Non-Invasive Positive Pressure Ventilation (HINPPV)
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.
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.
