Abstract: A method for performing cardiopulmonary resuscitation (CPR) includes elevating the heart of an individual to a first height relative to a lower body of the individual. The lower body may be in a substantially horizontal plane. The method may also include elevating the head of the individual to a second height relative to the lower body of the individual. The second height may be greater than the first height. The method may further include performing one or more of a type of CPR or a type of intrathoracic pressure regulation while elevating the heart and the head. The first height and the second height may be determined based on one or both of the type of CPR or the type of intrathoracic pressure regulation.

Abstract: A technique of construction is disclosed utilizing a plurality of upright posts bored from the top to define a bore that is coaxial with the post, there being cutaway portions entering into the sides of the post and communicating with the coaxial bore. A plurality of beams each has a tongue at both ends, the tongues fitting within the cutaway portions and being secured within the coaxial bore in the respective post. This securing is done with pins which are driven down into detent bores in the ends of the tongues, and the entire coaxial bore and pin and tongue detent structure is hidden by virtue of an overlying cap which is a press-fit into the coaxial bore, defining a flush surface with the top of the post.
