ABSTRACT

Adequate ventilation is the greatest concern of all the anaesthesiologists. Any disturbance in the ventilation process could result in serious hazards: hypoxemia or barotrauma. Deficient devices are one of many causes of such derangements. Some of the typical complications of airway/ventilation tools are described extensively in textbooks, but many other uncommon events can still occur. We described two interesting cases of device-related ventilation inadequacy, hoping that acquaintance with such jeopardizes would be helpful in emergency situations for other colleagues.
