ARDS患者典型的肺功能较小。越来越多的临床和实验证据表明，机械通气会导致高跨肺压差和肺单位过度膨胀，从而加重ARDS患者的急性肺损伤。因此，提倡使用低潮气量机械通气的相对形式的“肺休息”，以防止肺泡过度膨胀，这可以通过减速吸气流量的低容量、容量循环呼吸机或压力控制呼吸机(PCV)实现。本文的目的是提供一种简单实用的方法来管理ARDS患者的PCV。在我们的方法中隐含的是使用具有PCV软件和波形功能的呼吸机。
Patients with ARDS typically have functionally small lungs. A growing body of clinical and experimental evidence has demonstrated that mechanical ventilation that results in high transpulmonary pressure gradients and overdistention of lung units will potentiate the acute lung injury in patients with ARDS. A relative form of ''lung rest'' using low tidal volume mechanical ventilation that prevents alveolar overdistention has therefore been advocated, This may be achieved with low-volume, volume-cycled ventilation with a decelerating inspiratory flow or pressure-controlled ventilation (PCV). The goal of this article is to provide a simple and practical approach to the management of PCV in patients with ARDS. Implicit in our approach is the use of a ventilator of with PCV software and waveform capabilities.
