Pulmonary mattress
First Claim
1. A patient-support apparatus comprisingan upper frame having a head end and a foot end, the upper frame movable between a generally horizontal position and a position wherein the head end of the upper frame is spaced vertically below the foot end of the upper frame,an upper deck supported on the upper frame, the upper deck movable with the upper frame and including a seat section and a head section, the head section pivotable relative to the seat section to change the angular relationship between the head section and the seat section, anda control module controlling movement of the head section to coordinate movement of the head section with a change in attitude of the upper frame such that as the head section moves from a first position in which the head section is generally coplanar with the seat section to a second position in which the head section is inclined, wherein during a portion of the movement of the head section, the control module causes the upper frame to move from the generally horizontal position to a first position wherein the head end of the upper frame is lowered, and wherein continued movement of the head section upwardly causes the control module to cause the movement of the upper frame from the first position back toward the generally horizontal position.

1. A patient-support apparatus comprising
an upper frame having a head end and a foot end, the upper frame movable between a generally horizontal position and a position wherein the head end of the upper frame is spaced vertically below the foot end of the upper frame, an upper deck supported on the upper frame, the upper deck movable with the upper frame and including a seat section and a head section, the head section pivotable relative to the seat section to change the angular relationship between the head section and the seat section, and a control module controlling movement of the head section to coordinate movement of the head section with a change in attitude of the upper frame such that as the head section moves from a first position in which the head section is generally coplanar with the seat section to a second position in which the head section is inclined, wherein during a portion of the movement of the head section, the control module causes the upper frame to move from the generally horizontal position to a first position wherein the head end of the upper frame is lowered, and wherein continued movement of the head section upwardly causes the control module to cause the movement of the upper frame from the first position back toward the generally horizontal position.

15. A patient-support apparatus comprising
an upper frame having a head end and a foot end, the upper frame movable between a generally horizontal position and a position wherein the head end of the upper frame is spaced vertically below the foot end of the upper frame, an upper deck supported on the upper frame, the upper deck movable with the upper frame and including a seat section and a head section, the head section pivotable relative to the seat section to change the angular relationship between the head section and the seat section, and a controller controlling movement of the upper frame and the head section of the upper deck such that when the head section of the upper deck moves from a first, position sensed by an angle sensor in which the head section is generally coplanar with the seat section to a second position sensed by the angle sensor in which the head section is not coplanar relative to the seat section, and the controller causes the upper frame to move from a first position to a tilt position wherein the head end of the upper frame is lowered, and wherein continued articulation of the head section upwardly to a third position sensed by the angle sensor causes the controller to move the upper frame from the tilt position back to the first position.
