Extracorporeal membrane oxygenation (ECMO) is increasingly being used for patients with severe respiratory failure and has received particular attention during the coronavirus disease 2019 (COVID-19) pandemic. Evidence from two key randomized controlled trials, a subsequent post hoc Bayesian analysis, and meta-analyses support the interpretation of a benefit of ECMO in combination with ultra-lung-protective ventilation for select patients with very severe forms of acute respiratory distress syndrome (ARDS). During the pandemic, new evidence has emerged helping to better define the role of ECMO for patients with COVID-19. ⋯ Known risk factors for mortality in COVID-19 and non-COVID-19 patients are higher patient age, concomitant extra-pulmonary organ failures or malignancies, prolonged mechanical ventilation before ECMO, less experienced treatment teams and lower ECMO caseloads in the treating center. ECMO is a high resource-dependent support option; therefore, it should be used judiciously, and its availability may need to be constrained when resources are scarce. More evidence from high-quality research is required to better define the role and limitations of ECMO in patients with severe COVID-19.

Multicenter Study Observational StudyDelirium incidence and risk factors in patients undergoing non-invasive ventilation for acute respiratory failure: a multicenter observational trial.
Noninvasive ventilation (NIV) still has high failure rate when used for de novo acute respiratory failure (ARF). Delirium may impact the outcome, however data regarding its incidence, timing of occurrence and clinical predictors in this subset of patients are scarce. ⋯ Delirium onset in acute hypoxic patients undergoing NIV is frequent and negatively affects the outcome. Multiple related clinical factors should be addressed early on admission to prevent the delirium-related risk of NIV failure in these patients.

Long term feasibility of ultraprotective lung ventilation with low-flow extracorporeal carbon dioxide removal in ARDS patients.
To explore the feasibility of long-term application of ultraprotective ventilation with low flow ECCO2R support in moderate-severe ARDS patients and the reduction of mechanical power (MP) compared to lung protective ventilation. ⋯ The application of low flow ECCO2R support with ultraprotective ventilation was feasible minimizing the MP without deterioration in oxygenation in ARDS patients.

In the period immediately after birth, preterm infants are highly susceptible to lung injury. Ventilator-induced lung injury has been recognized as a major contributing factor for bronchopulmonary dysplasia (BPD) in preterm infants. Noninvasive respiratory support (NIRS) could decrease lung injury, and early respiratory support management might affect pulmonary outcomes. We conducted a study to evaluate the changes in early respiratory support management and their impact on respiratory outcome and complications of preterm infants in 3 different time periods over the last 13 years. ⋯ From 2007-2020, respiratory management was characterized by a marked reduction in invasive mechanical ventilation and an increase in the use of NIRS. Changes in early respiratory support management resulted in improved respiratory outcomes with a decrease in the overall incidence of BPD. It is likely that our aim to reduce lung injury by improving our respiratory management has contributed to a favorable outcome.

The aim of this study was to define the level of peak inspiratory pressure (PIP) and mean airway pressure ([Formula: see text]) at which a pneumothorax is produced in an in vivo ARDS neonate model. In addition, we analyzed the hemodynamic response and cerebral parameters during the progressive increase of intrathoracic pressure. ⋯ A progressive increase of PEEP at a constant driving pressure did not increase severe adverse events at the range of pressures that we routinely use in neonates with ARDS. Asystole, pneumothorax, and cerebral compromise appeared at high intrathoracic ranges of pressure. Hemodynamics must be strictly monitored in all patients during the performance of lung recruitment maneuvers because hemodynamic deflections emerge early, at a range of pressures commonly used in ventilated neonates with ARDS.
