Current opinion in critical care

Ventilator weaning forms an integral part in critical care medicine and strategies to shorten duration are rapidly evolving alongside our knowledge of the relevant physiological processes. The purpose of the current review is to discuss new physiological and clinical insights in ventilator weaning that help us to fasten liberation from mechanical ventilation. ⋯ A thorough understanding of the physiological adaptations during withdrawal of positive pressure ventilation is extremely important for clinicians in the ICU. We summarize and discuss novel insights in this field.

ReviewBedside noninvasive monitoring of mechanically ventilated patients.
Among noninvasive lung imaging techniques that can be employed at the bedside electrical impedance tomography (EIT) and lung ultrasound (LUS) can provide dynamic, repeatable data on the distribution regional lung ventilation and response to therapeutic manoeuvres.In this review, we will provide an overview on the rationale, basic functioning and most common applications of EIT and Point of Care Ultrasound (PoCUS, mainly but not limited to LUS) in the management of mechanically ventilated patients. ⋯ Bedside techniques - such as EIT and PoCUS - are becoming standards of the care for mechanically ventilated patients to monitor the changes in lung aeration, ventilation and perfusion in response to treatment and to assess weaning from mechanical ventilation.

A growing evidence shows that injurious spontaneous breathing, either too weak or too strong, may injure lung and diaphragm. The purpose of review is to understand why we need monitoring for safe spontaneous breathing, and to know the target value of each monitoring to preserve safe spontaneous breathing during assisted ventilation. ⋯ We summarize why we need monitoring for safe spontaneous breathing during assisted ventilation and what the target value of each monitoring is to facilitate 'safe' spontaneous breathing during assisted ventilation.

This article provides an overview of protein biomarkers for acute respiratory distress syndrome (ARDS) and their potential use in future clinical trials. ⋯ This article summarizes the current research on ARDS biomarkers and provides insights into how they should be integrated as prognostic and predictive enrichment tools in future clinical trials.

ReviewEmerging cellular and pharmacologic therapies for acute respiratory distress syndrome.
Advances in our understanding of the pathophysiology and biology of ARDS has identified a number of promising cellular and pharmacological therapies. These emerging therapeutics can modulate the immune response, reduce epithelial injury, target endothelial and vascular dysfunction, have anticoagulant effects, and enhance ARDS resolution. ⋯ Mesenchymal stromal cells, steroids, statins, vitamins, anticoagulants, interferons and carbon monoxide have therapeutic promise for ARDS. Identifying ARDS sub-populations most likely to benefit from targeted therapies may facilitate future advances.
