Abstract

An elevation device used in the performance of cardiopulmonary resuscitation (CPR) and after resuscitation includes a base and an upper support operably coupled to the base. The upper support is configured to incline at an angle relative to the base to elevate an individual'"'"'s upper back, shoulders and head. The elevation device includes a support arm coupled with the upper support. The support arm is movable to various positions relative to the upper support and is lockable at a fixed angle relative to the upper support such that the upper support and the support arm are movable as a single unit relative to the base while the support arm maintains the angle relative to the upper support. The elevation device also includes a chest compression device coupled with the support arm. The chest compression device is configured to compress the chest.
