简要总结
The purpose of this study is to compare lung recruitment in acute lung injury (ALI)/acute respiratory distress syndrome (ARDS) based on lower inflection point with transthoracic ultrasonographic assessment of lung recruitment.
详细描述
Sedated and sometimes temporary relaxed patients with ALI/ARDS on mechanical ventilation in semirecumbent position are included. Lower inflection point on pressure volume loop on ventilator Draeger Evita 4 with low continuous flow on volume controlled ventilation is measured with zero PEEP. Transthoracic lung ultrasound with linear probe is proceed on both hemithoraces when mechanical ventilation based on measured PEEP is started. We compare if real lung recruitment seen by ultrasound is the same as predicted by lower inflection point.
The procedure is a part of routine everyday respiratory monitoring in our unit.
