As part of the trusted Emergencies in series, the new edition of Respiratory Medicine provides a practical, up-to-date guide to the full spectrum of respiratory emergencies; from life-threatening conditions to more routine, yet equally challenging, situations encountered daily by the multidisciplinary teams caring for respiratory patients. Presented in a concise, point-by-point format, it also serves as a companion to the Oxford Handbook of Respiratory Medicine. Respiratory disease remains the leading cause of emergency hospital admissions, making a sound understanding of respiratory emergencies essential for all healthcare professionals assessing undifferentiated patients. This handbook adopts both a symptom-based and disease-specific approach. Symptom-focused sections explore common presentations, detailing initial assessment, investigations, and key differential diagnoses. These are followed by in-depth disease-based chapters. The final sections address important practical considerations, including test interpretation, frequently performed procedures, and essential investigations. Respiratory patients are increasingly cared for by a highly skilled multi-disciplinary team. This handbook will serve as an indispensable resource for all members of this group and will also prove invaluable to all staff involved in emergency and acute medicine, anaesthetics, critical care medicine, and primary care.
