This is with reference to an article by Arun et al.,[1] titled “Scavenging system—see the unseen to avoid disaster” published in the Indian Journal of Anaesthesia. Errors are not an uncommon feature associated with the scavenging system.[1,2] System errors can lead to adverse perioperative outcomes. Adverse outcomes reflect the perioperative quality of care.[3] It is the timely intervention and knowledge which can limit them. We report a case of sustained increase in the peak airway pressure and positive end-expiratory pressure (PEEP) in the breathing system during the preliminary machine check before the beginning of the case and its troubleshooting.
