Intraoperative monitoring had come a long way from a time when it was essentially primitive, relying heavily on clinical judgment with hardly any tools available to guide a clinician, to the present time when there are myriad modern gadgets that promise to make life easy for intraoperative physicians. Technological advancement has been a boon for the medical field with primary devices like pulse oximeter and capnography, which have become indispensable for practicing anesthesiologists, and newer tools like ultrasound, infrared spectroscopy, and transesophageal echocardiography, to name a few, which when used can give a sea of information to the anaesthesiologists to plan and manage patients intraoperatively.
Out of all these, the evolution and application of capnography have revolutionized the anesthesia practice becoming a formidable tool in the armory of anaesthesiologists, backed by abundant scientific data to claim its usefulness. Securing an airway is the most critical skill and job performed by anesthesiologists, emergency physicians, and paramedical staff. Once learned, it becomes a part of their routine, carrying it out just like other medical procedures. One reason for this ease is capnography, as it gives conclusive proof of intratracheal intubation. In this case report, we would like to explore the idea of whether capnography is definitive of correct intubation and ventilation at all times, with a particular emphasis on severe bronchospasm when the authors have found themselves in an arduous situation.
