The word cardioplegia combines the Greek cardio meaning the heart, and plegia paralysis. Technically, this means arresting or stopping the heart so that surgical procedures can be done in a still and bloodless field. Most commonly, however, the word cardioplegia refers to the solution used to bring about asystole of the heart, or heart paralysis. The main goals of hypothermic cardioplegia are:
4. to furnish or decorate with a tuft or tufts. 5. to arrange in a tuft or tufts. 6. to draw together (a cushion, mattress, etc.) by passing a thread through at regular intervals, the depressions thus produced usu. being ornamented with tufts or buttons.
The locations you place the buttons and how tight you pull them determine the tufted shape. Tufting is a process in which you add buttons to the surface of an upholstered piece of furniture to create diamond-or square-shaped clusters in the material.. Thread the upholstery needle with the button twine. Tie the twine on the button so that it does not come off, threading its tail through the marked location on the fabric and through the hole in the batting, the foam and through any other layers in the piece of furniture. Pull it through to the other side.
