Pulmonary fluid accumulation plays an important role in the development of post-traumatic pulmonary insufficiency. Yet initially diagnosis may be difficult. The measurement of transthoracic electrical impedance was used to detect early pulmonary fluid overload. In healthy test persons infusions of isotonic electrolyte solutions and diuresis were accompanied by changes of impedance dependent on the amount of infused or withdrawn fluid. In patients with pulmonary insufficiency a relatively low mean body impedance was recorded. Enforced diuresis resulted in a rise and in diminution of the alveolar-arterial oxygen difference.
肺内液体蓄积在创伤后肺功能不全的发生发展中起重要作用。然而，早期诊断可能困难。经胸电阻抗测量用于检测早期肺液体超负荷。在健康受试人员中，输注等渗电解质溶液和利尿时，阻抗会随着输注或排出液体量的变化而改变。在肺功能不全患者中，记录到相对较低的平均身体阻抗。强制利尿导致肺泡 - 动脉氧分压差升高和降低。
