PCV、PCIRV和VCIRV等几种新的通气方式应用了减速气流和反比通气,使MAP的调节可独立于PEEP。这几种新的通气方式在ICU中用于治疗ARDS等急性呼吸衰竭的治疗中,已证实可提高MAP、PaO_2,降低PAP、PEEP,其血流动力学变化相对稳定,并能提高肺顺应性。以上通气方式为ARDS等重症病人的呼吸治疗提供了更多的选择。 Several new ventilation modes, PCV, PCIRV and VCIRV, apply both decelerating airflow and inverse ventilation, making MAP adjustments independent of PEEP. These new ventilation methods in the ICU for the treatment of acute respiratory failure such as ARDS treatment, has been shown to increase MAP, PaO_2, reduce PAP, PEEP, the hemodynamic changes are relatively stable, and can improve lung compliance . Ventilation above ARDS and other critically ill patients with respiratory treatment provides more choices.
