The Fourth National Audit Project of the Royal College of Anaesthetists and Difficult Airway Society was designed to identify and study serious airway complications occurring during anaesthesia in the intensive care unit and emergency department. The group recently published its results in the British Journal of Anesthesia and lead author Tim M. Cook, FRCA, discusses the findings. He addresses specifically the use of continuous capnography to improve outcomes in patients that require intubations and gaps in care that may lead to adverse events. Cook is a consultant in anaesthesia and critical care medicine at Royal United Hospital in Bath, United Kingdom.
