Person support surfaces including set by preview function for continuous lateral rotation therapy

A person support apparatus comprising:

• a person support surface including an actuating device;
• and
• a controller operable to control the actuating device, the controller comprising a processor and a non-transitory memory device, the memory device including instructions that, when executed by the processor, cause the processor to operate the actuating device to simultaneously perform a rotation subroutine and a percussion and vibration (P&V) subroutine,
• wherein, during the rotation subroutine, the controller causes the actuating device to move the person support surface to a first rotation position for a first predetermined period of time,
• wherein the actuating device causes the actuating device to move the person support surface to a flat position for a second predetermined period of time after the first predetermined period of time,
• wherein the actuating device causes the actuating device to move the person support surface to a second rotation position for a third predetermined period of time after the second predetermined period of time,
• wherein, during the rotation subroutine, the controller causes the actuating device to perform P&V therapy, and
• wherein, during the rotation subroutine, the controller causes the actuating device to halt operation in response to detecting a fault condition, the fault condition including an incline position of a portion of the person support surface exceeding a predetermined threshold.

A method comprising:

• receiving user input including instructions to position an actuating device of a person support surface into a first preview position and setting the first preview position as a first evaluation position;
• receiving user input including instructions to position the actuating device into a second preview position and setting the second preview position as a second evaluation position;
• operating the actuating device to move the person support surface to the first evaluation position for a first predetermined period of time;
• operating the actuating device to move the person support surface to a flat position for a second predetermined period of time after the first predetermined period of time;
• and
• operating the actuating device to move the person support surface to the second evaluation position for a third predetermined period of time after the second predetermined period of time.
