High intensity NPPV is a new
strategy aim at maximal improvement in gas exchange in COPD patients with chronic
hypercapnic respiratory failure by increasing ventilator setting to the
individually tolerated maximum if necessary or to the level necessary to
achieve normocapnia.
In contrast to conventional NPPV in high intensity NPPV an
IPAP (Inspiratory positive airway pressure) is set in between 20-40 cm of H2O
initially in hospital setting and later at home. The randomised controlled
trail has shown that high intensity NPPV cause several benefit. Compare to
conventional strategy it showed-
- Improved gas exchange
- Improvement in breathing pattern and lung function
- Improvement in inspiratory muscle strength
- Increase haematocrit in anemic COPD and decrease haematocrit
in polycythemic COPD
- Improvement in dyspnea, quality of life and walking
distance.
