Abstract:
Electrical Impedance Tomography (EIT) is a non-invasive bedside imaging technique that provides real-time lung ventilation information on critically ill patients. EIT can potentially become a valuable tool for optimising mechanical ventilation, especially in patients with acute respiratory distress syndrome (ARDS). In addition, EIT has been shown to improve the understanding of ventilation distribution and lung aeration, which can help tailor ventilatory strategies according to patient needs. Evidence from critically ill patients shows that EIT can reduce the duration of mechanical ventilation and prevent lung injury due to overdistension or collapse. EIT can also identify the presence of lung collapse or recruitment during a recruitment manoeuvre, which may guide further therapy. Despite its potential benefits, EIT has not yet been widely used in clinical practice. This may, in part, be due to the challenges associated with its implementation, including the need for specialised equipment and trained personnel and further validation of its usefulness in clinical settings. Nevertheless, ongoing research focuses on improving mechanical ventilation and clinical outcomes in critically ill patients.
摘要:
电阻抗断层扫描(EIT)是一种无创的床旁成像技术,可为危重病人提供实时肺通气信息。EIT可能会成为优化机械通风的有价值的工具,尤其是急性呼吸窘迫综合征(ARDS)患者。此外,EIT已被证明可以提高对通气分布和肺通气的理解,这可以帮助定制通气策略,根据患者的需要。来自危重患者的证据表明,EIT可以减少机械通气的持续时间,并防止由于过度扩张或塌陷引起的肺损伤。EIT还可以在招募操作中识别肺部塌陷或招募的存在,这可能会指导进一步的治疗。尽管有潜在的好处,EIT尚未在临床实践中广泛使用。这可能,在某种程度上,由于与实施相关的挑战,包括需要专业设备和训练有素的人员,并进一步验证其在临床环境中的有用性。然而,目前的研究重点是改善危重患者的机械通气和临床结局.
