This disclosure relates to device for providing continuous negative abdominal pressure (CNAP) which selectively recruits (inflates) the dorsal (spinal region) collapsed areas of the lung, while enabling the patient to remain in the supine (usual) position. The CNAP device includes a rigid frame configured to have a shape and size to envelop a patient's lower chest and abdominal area while in a supine position with the frame having opposed edges which sit on a surface on which the supine patient is resting. A series of panels are mounted in the frame such that the series of panels extend around the patient's lower chest and abdominal area. A flexible sheet wrapped around the outside of the panels and is long enough to extend up to the patient's upper chest and down to the patient's thighs and wide enough to envelop the supine patient's lower chest and abdominal area. Sealing members are to seal the flexible sheet over the frame and panels and around the patient's lower chest and pelvis, wherein a chamber is formed between the patient and said device when the patient is enveloped by the device. An air inlet coupling extends through one of the panels and is attachable to a suction source which is configured to generate negative pressure of between about -5 to about -10 cm H2O inside the chamber.La présente invention concerne un dispositif pour fournir une pression abdominale négative continue (PANC) qui recrute de manière sélective (gonfle) les zones affaissées dorsales (région rachidienne) du poumon, tout en permettant au patient de rester en position couchée sur le dos (habituelle). Le dispositif PANC comprend un cadre rigide conçu pour avoir une forme et une taille permettant d'envelopper la poitrine inférieure et la région abdominale d'un patient, tandis qu'il se trouve en position couchée sur le dos, le cadre ayant des bords opposés qui s'appuient sur une surface sur laquelle repose le patient couché sur le dos. Une série de panneaux sont montés dans le cadre de t
