Numerous possibilities exist which may cause obstruction to ventilation under anesthesia resulting in a tight reservoir bag with low compliance. We report an interesting case where a reservoir bag twisted around its own neck and resulted in a tight bag situation. ⋯ We caution all anesthesiologists using the disposable modified Jackson-Rees breathing system to be aware of such an eventuality. We also urge the manufacturer to consider strengthening the neck of the reservoir bag by improving the quality of the material used for its construction.
