Electrical impedance tomography (EIT) is an emerging technology for the non-invasive monitoring of regional distribution of ventilation and perfusion, offering real-time and continuous data that can greatly enhance our understanding and management of various respiratory conditions and lung perfusion. Its application may be especially beneficial for critically ill mechanically ventilated patients. ⋯ This report is the result of a four-day expert meeting where we aimed to promote the consistent and reliable use of EIT, facilitating its integration into both clinical practice and research, focusing on the adult intensive care patient. We discuss the state-of-the-art regarding EIT acquisition and processing, applications during controlled ventilation and spontaneous breathing, ventilation-perfusion assessment, and novel future directions.

Meta Analysis Comparative Study
Central venous catheter-related infections: a systematic review, meta-analysis, trial sequential analysis and meta-regression comparing ultrasound guidance and landmark technique for insertion.
During central venous catheterization (CVC), ultrasound (US) guidance has been shown to reduce mechanical complications and increase success rates compared to the anatomical landmark (AL) technique. However, the impact of US guidance on catheter-related infections remains controversial. This systematic review and meta-analysis aimed to compare the risk of catheter-related infection with US-guided CVC versus AL technique. ⋯ US-guided CVC placement significantly reduces the risk of catheter-related infections compared to the AL technique, particularly when performed by experienced operators.
