Towards evidence based emergency medicine: best BETs from the Manchester Royal Infirmary. BET 2: should capnography be routinely used during procedural sedation in the Emergency Department?

A short cut review was carried out to establish whether capnography should be routinely used during procedural sedation in Emergency Departments. 206 papers were found using the reported searches, of which nine presented the best evidence to answer the clinical question. The author, date and country of publication, patient group studied, study type, relevant outcomes, results and study weaknesses of these best papers are tabulated. It is that capnography may provide early warning of ventilatory changes that could result in hypoxia.
