The DeBreather is a device that enables a person to end their own life by breathing air within a closed system. Normal respiration (breathing) consumes the oxygen in the closed system. The ‘by- product’ of the respiration, carbon dioxide (CO2)
, is continuously removed (scrubbed) from the recirculated air.
As the oxygen level drops, the person experiences a soporific, and almost intoxicating sensation. This leads to a peaceful loss of consciousness and death. The death is peaceful because the De- Breather removes exhaled carbon dioxide. It is a rise of carbon dioxide in exhaled air that normally produces an alarm sensation.
Death using the DeBreather is similar to that obtained using the Exit Bag fed with an inert gas, such as nitrogen (as described in the previous Chapter). There are, however, some important dif- ferences: there is no plastic bag involved, and there is no need for a compressed gas cylinder.
