This book provides a concise, clinical guide to the basics of airway and ventilation management for non-specialists working in pre-hospital and emergency medicine. It fulfills the need for a resource that simply and clearly explains the fundamentals of respiratory physiology, the pathophysiology behind respiratory failure and the practical aspects of artificial ventilation.  Artificial Ventilation: A Basic Clinical Guide, 2nd edition has been expanded to include guidance on mass ventilation during a viral pandemic with lessons learnt from the COVID-19 outbreak. It has been fully revised to support non-specialist medical and nursing personnel to understand the basics of artificial ventilation and to be able to improvise mass ventilation outside the ICU.
