Hyperpolarized Helium MRI to quantify regional lung damage and ventilation for improvement of recruitment strategy.

许多肺损伤需要机械通风来重新打开塌陷的肺空间，并为患者提供氧气。这项研究使用两种方法来监测呼吸过程中的肺：超极化氦气磁共振成像空间，和电阻抗断层扫描测量肺体积。这些信息将允许调整呼吸机压力，以在不增加肺损伤的情况下最大限度地转移氧气。更快地修复肺损伤和患者康复是这项研究的好处。

Many lung injuries need mechanical ventilation to reopen collapsed lung airspaces and supply oxygen to the patient. This study uses two methods to monitor the lungs during ventilation: Hyperpolarised helium MRI to image the airspace, and electrical impedance tomography to measure lung volume. This information will allow adjustment of ventilator pressure to maximize oxygen transfer without increasing lung damage. Quicker repair of lung damage and patient recovery are the benefits of this study.
