This book is focused on geriatric patients in critically ill conditions in the Emergency Room. Their percentage is very high, about 60% of the total percentage of patients, and the availability of intensive care admission is reduced for them as clearly shown during last Covid-19 pandemic. However, the modern approach is not yet able to stop the frailty cascade after hospitalization. In this book authors offer an analysis to overcome this gap. The volume contains two main sections: in the first one, authors discuss recommendations and guidelines for setting organizations and treatment through different case reports of practical management of critically ill geriatric patients (especially patients treated with noninvasive ventilation). In the second part, they analyze the territorial networks that take charge of the older patients. Furthermore, a chapter will be reserved to a comparative investigation of the different types of hospital territorial integration in Europe. The book, written by renowned experts in their fields and by their teams, represents a new tool rich of suggestions for all those physicians involved in the management of this frail population.
