Is there a place for nursing models in theatre nursing?

Nursing models are described as theoretical frameworks, or concepts, which represent what nursing is. A concept is 'something conceived in the mind, an idea, covering many similar things derived from study of particular instances'. You might ask, why do we need a model to explain what we do? But nursing has been notoriously difficult to define. Two definitions often cited are: 'The unique function of the nurse is to assist the individual, sick or well, in the performance of those activities contributing to health or its recovery (or a peaceful death) that he would perform unaided, if he had the necessary strength, will or knowledge. And to do it in such a way as to help him gain independence as rapidly as possible'. and: 'Nursing consists essentially of acts of helping or assistance ... the conditions which validate nursing action are lack of strength or will or knowledge. The nursing role, therefore, takes on physical and psychological assistance and its teaching function'. These provide us with a basis to initiate our ideas of nursing, but provide few answers to the 'how' of nursing.
