Abstract
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 pressure sensor is mounted to the frame for measuring a pressure inside the chamber and is connected to a display for displaying the pressure inside the chamber. An active pressure controller is connected to the pressure sensor, and a vacuum pump is in flow communication with inside the chamber and connected to the active pressure controller. The device includes a top up pump in flow communication with inside the chamber and connected to the active pressure controller which is programmed to instruct the vacuum pump to provide negative pressure in the chamber to start decompressing the chamber, and to instruct the top up pump to maintain the negative pressure in the chamber.
