Abstract:
The ventilator-induced lung injury (VILI) was centered on the "static" characteristics of the mechanical ventilation in early phases (tidal volume, plateau pressure, positive end-expiratory pressure and driving pressure). But the "dynamic" characteristics of ventilation must not be ignored (respiratory rate and flow). Mechanical energy and mechanical power (the pace of performing energy load) regarding all factor have won wide spread attention. The energy generated by mechanical ventilation is mainly used to expand respiratory system and overcome resistance, a fraction of energy acts on lung tissues probably inducing "heat" and inflammation that is related to lung injury. The review described recent conceptual advances regarding the mechanical energy and power, and the relationship with VILI, hoping to help further understanding the risk factors for VILI.
