On omissions and artificial hydration and nutrition

Understanding what sorts of things one might be responsible for is an important component of understanding what one should do in situations where the administration of artificial hydration and nutrition are required to sustain the life of a patient. Relying on work done in the philosophy of action and on moral responsibility, I consider the implications of omitting the administration of artificial hydration and nutrition and instances in which the omitting agent would and would not be responsible for the death of the patient. I am primarily interested in arguing against those who wish to seat responsibility for the death of a patient in an underlying pathology, even when the underlying pathology is not the cause of the patient's death.
