This publication is produced as an addition to the already published Percutaneous Emergency Oxygenation Strategies in the "Can't Intubate, Can't Oxygenate" Scenario by the same author. It contains a set of check-lists provided for instructors who plan to teach the PEO strategies in their own establishments. The check-lists are formed around a new acronym TRAPPED which has been introduced from our experience in teaching these strategies. Those who have already purchased the aforementioned eBook can receive this addition free of charge by contacting the author and providing their proof of purchase. All proceeds made from this book will be used to fund ongoing workshops and training.
