[Airways and respiratory function: preoperative screening--anaesthetic and intensive care aspects and considerations]

The risk factors for respiratory complications can broadly be classified as patient-related or procedure-related factors. Knowledge about pathophysiological and pharmacological aspects of the patients' condition is essential for their safe care during preoperative assessment, intra-operative management and, if necessary, postoperative intensive care. A good understanding of the risk factors leading to the development of postoperative respiratory complications should result in the implementation of perioperative strategies designed to prevent their occurrence and reduce severity. Special information regarding airway and lung aspects as well as cases involving different types of anaesthesia and surgical procedures are also discussed
