Anaesthesia & Critical Care

Interdisciplinary Collaboration in Systems Medicine (ICSM)

Aim and expertise

We design, develop and apply pathophysiological models of human organ systems, with the aim of addressing issues of impact in critical illness and medical crisis scenarios.

The Interdisciplinary Collaboration in Systems Medicine (ICSM) simulation suite is an integrated and validated computational model of a number of organ systems, including the heart, blood vessels (and blood) and the lungs and is developed in collaboration with the School of Engineering at University of Warwick.

Research issues

Critical illness and medical crises are a huge drain on our society. They consume a disproportionate part of medical budgets and are tremendously disruptive to patients and their families. Due to the unpredictable nature of these issues, the heterogeneity of patients and the time critical nature of events, recruitment to clinical studies is difficult, and the results disappointingly noisy and unhelpful. There has thus developed a pressing need for a novel method to answer questions of crucial importance to these most vulnerable of patients.

What we are doing about...

  • Personalising and optimising the therapy delivered in the Intensive Care Units (ICU)
  • Obtain novel understanding of the pathophysiological state of cardiac arrest, test new cardiopulmonary resuscitation strategies and investigate clinical management strategies after cardiac arrest
  • Explore optimal rescue strategies using the Optiflow (a recent developed oxygen therapy device that delivers high-flow, humidified oxygen via nasal cannulae) in-silico obese and pregnancy subjects.
  • Prolongation of apnoea - improving the high-risk period of anaesthetic induction, and optimising gas exchange in-silico healthy and pregnancy subjects
