• This book provides extensive coverage of most primitive to most modern monitoring technologies • A comprehensive yet concise description of various monitors is included • The book uniquely includes structured text on obstetric critical care, which we felt was lacking in most textbooks available previously • Extending beyond clinical realms, the book also focuses on research based upcoming monitoring ideas like quantifying pain, sedation, and maternal-fetal safety improvement • The book is aptly divided into sections that discuss monitoring technologies of various organ systems like cardiac, respiratory, hematology, and nervous system • Other special highlight of the book includes a section on monitoring of metabolic parameters (endocrine, arterial blood gases, and biochemical parameters) that clearly make this book distinct from all other books published with similar purview • Multispecialty global experts spanning intensive care, anesthesia, medicine, and surgery have enriched the book with clinical practical ideas that targets almost all subspecialties readers • Essentially, the book not only provides relevant material for postgraduate students but also extends out to reach the clinicians in both teaching and nonteaching hospitals.
