A crisis situation may present itself at anytime and optimal management is essential to achieving the best outcomes. For the individual a crisis is often a rare event and they may find themselves having to manage something for which they have had little or no experience. This app was created using operating room crisis checklists available from projectcheck.org with modifications to more accurately reflect Australian medical practice where appropriate. It is an educational tool only and aims to assist in understanding what to do if you are faced with a medical crisis. It does not constitute medical treatment advice and is not authorised for use in clinical practice.
