Patients do not support any weight above them other than a > 6" layer of fiberglass insulation. Now, as I understand it, standing patients vertically is done because of the state of dewar design. However, given this whole new design for patient storage, perhaps it would be less stressful on the patients to store them horizontally? They take up the same volume either way. It might also make sense to place the patients on some sort of form-fitting surface, perhaps even sand escavated to fit patient contours, to evenly distribute the stresses across the bearing surface of the patient.
