Abstract
Failure of ventilation of an anesthetised patient due to problems in mechanical ventilator is not uncommon. The proper functioning of machine should be ensured before anesthetising a patient by the automated checking system or manually by the attending anaesthesiologist. However, sudden malfunction of some system of the machine during operation may cause the ventilator to stop risking the patient’s life. About one third of the equipment problems are due to anesthesia machine and one quarter of the problems are due to human error. We present a case of malfunction of anesthesia ventilator due to an unusual cause of blockage of anesthesia gas scavenging system.

It was found that someone had hanged a lead apron on the ISSN 2091-2889 (Online) ISSN 2091-2412 (Print) JCMC/ Vol 10/ No 1/ Issue 31/ Jan-Mar, 2020 back of the machine which was obstructing the anesthetic gas scavenging system blocking the outflow of the machine causing back pressure
Intraoperative problems can be due to machine/equipment/s malfunction, human errors or patient related factors
Summary
The safety of conduction of anaesthesia depends upon the proper functioning of the anaesthesia equipment. With the malfunction of the anaesthesia equipment, the morbidity and mortality of patient increases. Anaesthesia machine malfunction is one of the most common cause of equipment related morbidity in anaesthesia.[1] There are various problems reported related with anaesthesia machine.
