The present invention is directed to improved systems and methods for processing respiratory signals derived generally from respiratory plethysmography, and especially from respiratory inductive plethysmographic sensors mounted on a garment for ambulatory recording. The systems and methods provide improved signal filtering for artifact rejection, improved calibration of sensor data to produce outputs indicative of lung volumes. Further, this invention provides improved systems and methods directed to processing lung volume signals, however measured or derived, to provide improved determination of respiratory parameters and improved recognition of selected respiratory events.

Systems and methods for respiratory event detection

An air-filled mattress with virtually no air loss has a plurality of air-filled bags grouped into zones of uniform air pressure. A controller monitors the air pressure in each zone and activates a blower to adjust the pressure in any zone in which the measured pressure differs from the desired pressure by more than a threshold amount. The blower is otherwise deactivated. The bags are deflated by reversing the direction of flow from the bags to the blower. The bags are fastened to a mattress base using an attachment fitting that receives an elongated bead on the bag's bottom edge into a chamber along the mattress base fitting. The mattress base can be attached to any of a variety of different conventional bed frames. Tabs fastened to the mattress base having a hinge and a hand malleable aluminum plate can be bent to grasp a variety of different bed frames. A unique air manifold between the blower and the bags, a unique hose coupling between the blower and the manifold and a unique air coupling between the manifold and the bags are also described. The controller is incorporated into an independent housing with an adjustable handle, wheels and a movable keyboard and is operated according to a four-mode control program.

Fluid filled flotation mattress

An alternating pressure pad, useful between a mattress and a bed-ridden person for preventing the occurrence of bed sores, defines two separate sets of interdigitated transverse inflatable body support chambers. The support chambers are alternately inflated and deflated to provide alternating areas on his body where a person lying on the pad is supported by the pad. In a leg and foot section of the pad, the support chambers have a smaller inflated diameter than the other chambers of each set to provide effective support, and freedom from support, of the heel and ankle areas of the body when those chambers are alternately inflated at a pressure consistent with comfort of the person. A body air chamber is defined in the pad over and independent from the support chambers under a pad top sheet which has a predetermined portion of its area open for air to flow through it.

Alternating pressure pad

A foam pad containing slits in its upper surface is disclosed. In its preferred embodiment the pad is adapted to be positioned on a bed in a supporting relationship to a patient. The pad has head and foot supporting sections, each in the form of a convoluted checkerboard pattern of rows of peaks separated by depressions. A torso supporting section is located between the head and foot supporting sections comprising substantially parallel ribs separated by substantially parallel valleys. The slits are located on the torso supporting section, transverse to the ribs, forming a diamond-shaped area. Each slit varies in depth decreasing from the center of the pad towards the sides of the pad. Additionally, the overall depth of the slits is progressively shallower towards the head and foot supporting sections of the pad. In another embodiment, slits of the same configuration are used with a pad having a smooth upper surface which supports at least a portion of a body. The configuration of the slits cause the pad to be softer permitting the bony prominences of the body in contact with the slits, to sink deeper into the pad than other portions of the body. This substantially reduces the pressure placed on the skin covering these bony prominences thereby helping to prevent the formation of decubitus ulcers.
