Capnography has been inducted as a standard of anesthesia monitoring during perioperative care of the patients. It's a simple, reliable and cost-effective tool having many clinical applications. Its uses range from operating rooms, accident and emergency wards, high dependency units, critical care units, pediatric critical care wards and postoperative recovery bays. Many factors, including non-availability, or lack of knowledge, negligence or laziness by the end-users, result in lack of use of such an essential monitoring resource at the expense of the patient safety. A change in attitude is the need of the hour for the medical staff towards its use and it has to be started now.
