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.
Tufting, a process of inserting pile yarns into a backing material, accounts for more than 90% of the carpet produced today. This process revolutionized the manufacture of carpet by speeding production and making carpet more affordable for the masses. Tufting is a process very similar to embroidery. Yarn is inserted into a backing material to form the face material. In fact, tufting originated from the manufacture of embroidered chenille bedspreads and was gradually transformed into rugs and later broadloom carpet.
