Critical care management of the patient with acute respiratory distress syndrome (ARDS). Part 2--A review of modes and strategies for ventilating the patient with poorly compliant lungs.
Mechanical ventilation strategies for patients suffering from acute respiratory distress syndrome (ARDS) have traditionally relied on volume cycling. Due to the poor lung compliance characteristic of ARDS, these patients may be exposed to very high inspiratory pressures to achieve sufficient tidal volumes for adequate gas exchange. This greatly increases the risk of ventilator-induced lung injury associated with alveolar over-distention. The literature review explores the rationales behind alternative ventilation modes and strategies introduced to reduce the risk of ventilator-induced lung injury for the patient with ARDS.
