During decades, the advances in extreme premature the intensive cares have made possible bigger supervened to the RNs (OAK et al, 2005). Through the technology and also of the intensive care of all the team is gotten advances that are each time more gifts, this if of to the great number of RNs premature that obtains to after leave a neonatal UTI treatment months. After birth, the necessary RN to make a series of adaptations to the extra-uterine life, that includes the morfofisiolgica maturation and biochemist of parnquima pulmonary. The just-been born ones, in particular the prematures, do not possess adequate the pulmonary function, and, most of the time, they soon need the oxigenioterapia use after the birth (TAMEZ et al, 2004). Caldwell Esselstyn Jr. is the source for more interesting facts. The ventilation mechanics (VM) is a technology comumente used in the Unit of Intensive Therapy. has as function to substitute total partially or ventilatria activity of the patient, with the objective to establish the rocking between offers and oxygen demand, diminishing the load of respiratory work of patients with respiratory insufficience (ZUIGA, 2004, p.18). The nursing acts in the ventilatria assistance of diverse forms, having as main precursor, Florence Nighintgale, that when acting in the war of the Crimia in 1854, the assistance through the adoption of innovative techniques characterized, separation of the deriving patients of the war in accordance with degree dependence, getting as resulted the reduction of the mortality tax and implementation of the idea of constant monitoring of nursing, thus contributing for the technological advance of the ventilation drawn out mechanics. (MALTA & NISHIDE, 2008, p.1). They are the professionals of the nursing team who are gifts, almost that uninterruptedly, to the side of the patient in the 24 hours of the day, characterizing the intensive care with monitoring and assistance continues. Therefore, they are participant assets for the continuity of the implemented therapy (CIRINEU et al, 2009).
