High Intensity Non-Invasive Positive Pressure Ventilation (HINPPV)

This is a single arm interventional study. Hypercapnic COPD participants that meet eligibility criteria will receive high intensity non-invasive positive pressure ventilation(HINPPV). Participants will receive HINPPV via bilevel positive airway pressure (BiPAP) via a Synchrony ventilator if they require an inspiratory positive airway pressure (IPAP) less than or equal to 30 cmH2O; or the Trilogy ventilator if they require an IPAP greater than 30 cmH2O.
