Multicenter StudySevere hypercapnia and outcome of mechanically ventilated patients with moderate or severe acute respiratory distress syndrome.
To analyze the relationship between hypercapnia developing within the first 48 h after the start of mechanical ventilation and outcome in patients with acute respiratory distress syndrome (ARDS). ⋯ Severe hypercapnia appears to be independently associated with higher ICU mortality in patients with ARDS.

Ability of ICU Health-Care Professionals to Identify Patient-Ventilator Asynchrony Using Waveform Analysis.
Waveform analysis by visual inspection can be a reliable, noninvasive, and useful tool for detecting patient-ventilator asynchrony. However, it is a skill that requires a properly trained professional. ⋯ HCPs who have specific training in mechanical ventilation increase their ability to identify asynchrony using waveform analysis. Neither experience nor profession proved to be a relevant factor to identify asynchrony correctly using waveform analysis.

Randomized Controlled Trial Multicenter StudyNeurally adjusted ventilatory assist as an alternative to pressure support ventilation in adults: a French multicentre randomized trial.
Neurally adjusted ventilatory assist (NAVA) is a ventilatory mode that tailors the level of assistance delivered by the ventilator to the electromyographic activity of the diaphragm. The objective of this study was to compare NAVA and pressure support ventilation (PSV) in the early phase of weaning from mechanical ventilation. ⋯ NAVA is safe and feasible over a prolonged period of time but does not increase the probability of remaining in a partial ventilatory mode. However, NAVA decreases patient-ventilator asynchrony and is associated with less frequent application of post-extubation noninvasive mechanical ventilation.

Elevated Plasma Levels of sRAGE are Associated with Non-Focal CT-Based Lung Imaging in ARDS patients.: A Prospective Multicenter Study.
During ARDS, CT can reveal two distinct lung imaging patterns, focal or nonfocal, with different responses to positive end-expiratory pressure, recruitment maneuvers, and prone position. Nevertheless, their association with plasma biomarkers and their distinct functional/pathobiological mechanisms are unknown. The objective of this study was to characterize focal and nonfocal patterns of lung CT-based imaging with plasma markers of lung injury. ⋯ Plasma sRAGE is associated with a nonfocal ARDS. Such novel findings may suggest a role for RAGE pathway in an underlying endotype of impaired alveolar fluid clearance and stimulate future research on the association between ARDS phenotypes and therapeutic responses.

Multicenter StudyThe feasibility and safety of extracorporeal carbon dioxide removal to avoid intubation in patients with COPD unresponsive to noninvasive ventilation for acute hypercapnic respiratory failure (ECLAIR study): multicentre case-control study.
The aim of the study was to evaluate the feasibility and safety of avoiding invasive mechanical ventilation (IMV) by using extracorporeal CO2 removal (ECCO2R) in patients with acute exacerbation of chronic obstructive pulmonary disease (COPD) and acute hypercapnic respiratory failure refractory to noninvasive ventilation (NIV). ⋯ The use of veno-venous ECCO2R to avoid invasive mechanical ventilation was successful in just over half of the cases. However, relevant ECCO2R-associated complications occurred in over one-third of cases. Despite the shorter period of IMV in the ECCO2R group there were no significant differences in length of stay or in 28- and 90-day mortality rates between the two groups. Larger, randomised studies are warranted for further assessment of the effectiveness of ECCO2R.
