ReviewHome oxygen monitoring and therapy: learning from the pandemic.
Home oxygen monitoring and therapy have been increasingly used in the management of patients with chronic diseases. The COVID-19 pandemic has prompted the rapid uptake of remote monitoring programmes to support people with COVID-19 at home. This review discusses the recent evidence and learning in home oxygen monitoring and therapy from the pandemic. ⋯ Recent evidence indicates that home oxygen monitoring therapy programmes are feasible in acute disease, but further research is needed to establish whether they improve patient outcomes, are cost-effective and to understand their equity impact.

Critical care medicine revolves around syndromes, such as acute respiratory distress syndrome (ARDS), sepsis and acute kidney injury. Few interventions have shown to be effective in large clinical trials, likely because of between-patient heterogeneity. Translational evidence suggests that more homogeneous biological subgroups can be identified and that differential treatment effects exist. Integrating biological considerations into clinical trial design is therefore an important frontier of critical care research. ⋯ Integrating our knowledge on biological heterogeneity into clinical trial design, which has revolutionized other medical fields, could serve as a solution to implement personalized treatment in critical care syndromes. Changing the trial design by using predictive enrichment, incorporation of the evaluation of time-dependent changes and biological markers as surrogate outcomes may improve the likelihood of detecting a beneficial effect from targeted therapeutic interventions and the opportunity to test multiple lines of treatment per patient.

ReviewThe impact of the coronavirus pandemic on sedation in critical care: volatile anesthetics in the ICU.
To reflect on the impact of the coronavirus pandemic on sedation for mechanically ventilated patients. ⋯ Although further research is needed to establish the role of inhaled anaesthetics in critical care sedation toolkit, maintaining the spirit of innovation ignited during the recent coronavirus pandemic would require ongoing collaboration and streamlining of processes among healthcare, research and regulatory institutions.

The last 25 years have seen considerable development in modes of closed-loop ventilation and there are now several of them commercially available. They not only offer potential benefits for the individual patient, but may also improve the organization within the intensive care unit (ICU). Clinicians are showing both greater interest and willingness to address the issues of a caregiver shortage and overload of bedside work in the ICU. This article reviews the clinical benefits of using closed-loop ventilation modes, with a focus on control of oxygenation, lung protection, and weaning. ⋯ Recent studies have primarily demonstrated the safety, efficacy, and feasibility of using closed-loop ventilation modes in the ICU and postsurgery patients. Large, multicenter randomized controlled trials are needed to assess their impact on important short- and long-term clinical outcomes, the organization of the ICU, and cost-effectiveness.

ReviewProne positioning of nonintubated patients with acute hypoxemic respiratory failure.
Since the early pandemic, prone positioning has been broadly utilized for nonintubated patients (so-called 'awake prone positioning, APP') with coronavirus disease 2019 (COVID-19) induced acute hypoxemic respiratory failure (AHRF). ⋯ APP has been shown to improve oxygenation for patients with COVID-19 induced AHRF and is a safe treatment. However, the benefits of reducing intubation rates are only seen in moderate-to-severe patients who are undergoing HFNC treatment. In these patients, APP should be initiated early and with a target of at least 8 h/day of APP. Pillows under the body and patients-healthcare team collaboration to find the optimal position is essential to enhance patients' adherence. Oxygenation improvement and changes in the lung ultrasound findings may help to identify those patients who are more likely to avoid the need for intubation.
