Positive pressure ventilation (PPV) treatments in obese patients are more likely to lead to ventilator-induced lung injuries (VILI). The purpose of this project was to develop a continuous negative abdominal pressure ventilator (CNAP) to work in tandem with PPV to reduce the positive pressure. The design consists of a Shell, Sealing, Locking, Frame, and Pump subsystems with easy removal and CNAP function. The clear shell is clasped to a frame, which can be attached to any standard medical bed, and neoprene seals to the patient. The lightweight device extends from the top of the sternum to the hipbone line. It maintains a vacuum range of -10 to -30 cmH2O for 6 hour work-2 minute rest cycles for 3-4 weeks. The combination of the CNAP and PPV can potentially reduce the occurrence of VILI.
