Non-invasive ventilation is found to help reduce dynamic hyperinflation during exercise in COPD patients. Latest research conducted by Clancy J. Dennis and colleagues at the faculty of medicine and health at the University of Sydney found that non-invasive ventilation could help increase endurance in COPD patients, apart from minimising dynamic hyperinflation during exercise. The research report, published in Chest, said that  a randomized, crossover trial involving 19 participants with COPD proved that the exercise endurance time increase of 152 seconds was greater than the minimal clinically important difference. Importantly, the inspiratory capacity improvement at isotime and at the end of exercise with noninvasive ventilation with titrated expiratory positive airway pressure exceeded 200 mL in 79 percent of participants compared with no noninvasive ventilation.
