PURPOSE OF REVIEW: Mechanical ventilation is a cornerstone of ICU treatment. Because of its interaction with blood flow and intra-abdominal pressure, mechanical ventilation has the potential to alter hepato-splanchnic perfusion, abdominal organ function and thereby outcome of the most critically ill patients. RECENT FINDINGS: Mechanical ventilation can alter hepato-splanchnic perfusion, but the effects are minimal (with moderate inspiratory pressures, tidal volumes, and positive end-expiratory pressure levels) or variable (with high ones). Routine nursing procedures may cause repeated episodes of inadequate hepato-splanchnic perfusion in critically ill patients, but an association between perfusion and multiple organ dysfunction cannot yet be determined. Clinical research continues to be challenging as a result of difficulties in measuring hepato-splanchnic blood flow at the bedside. SUMMARY: Mechanical ventilation and attempts to improve oxygenation such as intratracheal suctioning and recruitment maneuvers, may have harmful consequences in patients with already limited cardiovascular reserves or deteriorated intestinal perfusion. Due to difficulties in assessing hepato-splanchnic perfusion, such effects are often not detected.
