The best timing to perform a tracheostomy remains debatable in the literature. This study investigates patient-centric as well clinician-centric outcomes when looking at tracheostomy timing, and finds that patients who receive a tracheostomy earlier are able to start mobilising out of bed, talking again and eating and drinking much earlier than those that receive a tracheostomy late. These are important outcomes for our patients.

This article recounts the development of the COVID-19 Critical Care Consortium, from a small interest study in early January to a consortium expanding over 300 hospital sites by early May 2020. The article highlights the incredible collaboration that is providing data to support medical professionals through the pandemic, when there are very limited resources available.

This letter to the Editor comments on a study that used normothermic ex vivo perfusion and plasma cross-circulation to preserve donor hearts for 72 hours. The letter highlights that the key component of donor BD was missing form the animal model, which may have influenced outcomes, and draws comparisons betwen hypothermic ex vivo perfusion for donor herat preservation, which has also been shown in large animal models of heart transplantation to improve outcomes post-transplant.

This systematic review highlights the paucity of available animal models of heart transplant that incorporate donor brain death, and demonstrates the significant heterogeneity that exists (and details reported) in the few available models, potentially hindering progression of the field.
There is a significant body of work that has emerged in last 5 years to guide antimicrobial dosing on ECMO. The article discusses whether antimicrobial dosing, based on principles of drug dosing during critical illness, along with therapeutic drug monitoring will suffice during ECMO.

The use of Extracorporeal membrane oxygenation (ECMO) is on the rise, however there are still significant complications including bleeding and thrombosis. In the following study led by Post Doc Katrina Ki, the CCRG team has shown that high vs low flow rates in ECMO differentially alter a number of haemostatic parameters.

ECMO support enables clinicians to rest the diseased native lungs while they heal and recover. However optimal mechanical ventilation strategy on ECMO is not tested in clinical studies. While protecting lungs from iatrogenic harm during mechanical ventilation is important, this article argues that excessive lung testing may actually be detrimental to the patient.

Patient selection is key for the success of ECMO therapy. There is a growing population of immunosuppressed patients globally. Respiratory failure is a leading cause of death in these patients and this article explores the risk:benefits of applying ECMO in the immunosuppressed
