Abstract
Applied respiratory physiology is crucial for perioperative patient management. This article reviews respiratory mechanics, gas exchange, and ventilation regulation, focusing on their practical applications from preoperative assessment to postoperative recovery. Cardiopulmonary exercise testing (CPET) is emphasized for predicting perioperative risk, with metabolic equivalents (METs) highlighted as indicators of cardiovascular fitness. The significance of oxygen delivery (DO2) components and types of hypoxia are detailed. Anaesthesia's effects on respiratory physiology, including the suppression of ventilatory response and impact on upper airway muscles, are analysed. Postoperative strategies to prevent atelectasis, such as positive end-expiratory pressure (PEEP) and recruitment manoeuvres, are discussed.
期刊介绍：
Anaesthesia and Intensive Care Medicine, an invaluable source of up-to-date information, with the curriculum of both the Primary and Final FRCA examinations covered over a three-year cycle. Published monthly this ever-updating text book will be an invaluable source for both trainee and experienced anaesthetists. The enthusiastic editorial board, under the guidance of two eminent and experienced series editors, ensures Anaesthesia and Intensive Care Medicine covers all the key topics in a comprehensive and authoritative manner. Articles now include learning objectives and eash issue features MCQs, facilitating self-directed learning and enabling readers at all levels to test their knowledge. Each issue is divided between basic scientific and clinical sections. The basic science articles include anatomy, physiology, pharmacology, physics and clinical measurement, while the clinical sections cover anaesthetic agents and techniques, assessment and perioperative management. Further sections cover audit, trials, statistics, ethical and legal medicine, and the management of acute and chronic pain.
