Since inhalational anesthetics are flammable, various checklists have been developed to confirm that the machine is ready for use, that the safety features are active and the electrical hazards are removed. 373–403. However, addition of several mechanical, electronic and electric components has contributed to recurrence of some of the older problems such as leak or obstruction attributable to newer gadgets and development of newer problems. In case of ascending bellows, ensure the bellows reach the top of the bottle and then turn off the fresh gas flows. J Anaesthesiol Clin Pharmacol 2012;28:270-1.
