High Intensity Non Invasive Pos.Pressure
The High Intensity Non-invasive Positive Pressure (HINPPV) trial is a single arm interventional study. Hypercapnic Chronic Obstructive Pulmonary Diseased (COPD) participants that meet eligibility criteria will receive 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.

SECONDARY outcome

Timeframe: Before and after 3 months of therapy

Health status was assessed by completing different surveys at baseline and after 3 months of therapy. The Calgary Sleep Apnea Quality of Life was administered at baseline and 3 months. It is a 35-item, interview-administered scale, the SAQLI evaluates four domains of quality of life associated with sleep apnea: daily functioning, social interactions, emotional functioning, and symptoms. The SAQLI use a 7-point Likert scale ranging from 1 (maximal impairment) to 7 (no impairment).

SECONDARY outcome

Timeframe: Before and after 3 months of therapy

The Maximal inspiratory pressure (MIP) is the maximum negative pressure that can be generated from one inspiratory effort starting from functional residual capacity (FRC) or residual volume (RV). This was assessed at baseline and after 3 months of therapy.

SECONDARY outcome

Timeframe: Before and after 3 months of therapy

The modifed Borg scale was used to measure dyspnea. The Dyspnea Borg scale measures patients perceived level of dyspnea. The scale ranges from 0 to 10, 0- nothing at all and 10 is maximal.

SECONDARY outcome

Timeframe: Before and after 3 months of therapy

Population: Only 5 participants completed the overnight polysomnography (PSG) for this trial.

Sleepiness will be evaluated by measuring the the baseline and 3 month Epworth Sleepiness Scale. The Epworth Sleepiness Scale is an 8 question survey regarding daytime sleepiness. The higher the score the higher the chance of dozing during the day. Each question is rated on a 0 to 3 scale of chance of dozing or sleeping. 0 would be no chance, 3 would be the highest chance.
