Comparative StudyContinuous positive airway pressure versus continuous negative pressure around the chest for patients with acute exacerbation of chronic obstructive pulmonary disease in the intensive care unit: a pilot study.
With chronic obstructive pulmonary disease (COPD) exacerbations, continuous positive airway pressure (CPAP) has been used to overcome the threshold load provided by intrinsic positive end expiratory pressure and decrease the inspiratory work of breathing. In this pilot study, we observed whether a continuous negative pressure (CNP) around the thorax and upper abdomen with a shell and wrap would provide a similar level of relief in dyspnoea. ⋯ The CNP was similar to CPAP except CNP was more comfortable.
