Lung-Protective Ventilation.

Lung-Protective Ventilation. Annu Rev Nurs Res. 2017 Jan;35(1):37-53 Authors: Marley RA, Simon K Abstract Historically, mechanical ventilation of the lungs utilizing relatively large tidal volumes was common practice in the operating room and intensive care unit (ICU). The rationale behind this treatment strategy was to yield better patient outcomes, that is, fewer pulmonary complications, and a reduction in morbidity and mortality. As evidence-based practice has evolved, potential harmful effects of traditional, nonphysiological mechanical ventilation (ventilation with larger tidal volumes and the tolerance of high airway pressures) even in shortterm treatment have been shown to correlate with systemic inflammation and the development of ventilator-associated lung injury. Lung-protective ventilation principles using more physiological tidal volumes, avoiding high inspiratory plateau pressures, along with appropriate levels of positive end-expiratory pressure have been shown to decrease pulmonary complications and improve outcomes in patients with acute respiratory distress syndrome requiring ongoing ventilatory support in the ICU. In addition, current research is beginning to validate the benefit of providing more physiologic ventilator support in the operating room, particularly for high-risk patients undergoing major abdominal surgery, in minimizing acute lung injury. A review of lung-protective ventilation measures including bene...
