Jack Kevorkian
Jacob "Jack" Kevorkian , commonly known as "Dr. Death", was an American pathologist, euthanasia activist, painter, composer and instrumentalist.

 attached to a face mask with a tube. A valve must be released to start the gas flowing. Depending on the person's disability, a makeshift handle may be attached to the valve to make it easier to turn. Or, with the valve in the "open" position, a clip or clothespin could be clamped on the tubing. Pulling it off allows the gas to flow. By Kevorkian's estimates, this method took 10 minutes or longer. Sometimes he encouraged people to take sedatives or muscle relaxants to keep them calm as they breathed deeply of the gas.

Carbon monoxide is hazardous to others who may discover the body (family, medical workers, police).

) with compressed nitrogen and then regulating this with a jet assembly to give a flow of around 10 litres per minute into the standard plastic "Exit Bag". This equipment has some small advantages over the helium method:

  • The gas is more physiological

    , with no chance of adverse reaction (helium is reported to cause some twitching during death);
  • If there is any leakage in the period of storage of the cylinder, it can be topped up at any time to the recommended 400 pound per square inches (2,757.9 kPa). The helium party balloon cylinders cannot be refilled and, if they leak over time, must be discarded.


Nitschke called it "flawless" and "undetectable", saying the new process uses ordinary household products available from hardware stores. Inhaling the pure nitrogen, patients lose consciousness immediately (in approximately 12 seconds) and die a few minutes later.

Nitschke said: "So it's extremely quick and there are no drugs. Importantly this doesn't fail – it's reliable, peaceful, available and with the additional benefit of undetectability." However, Nitschke commented in 2010 that if helium is used, new autopsy

Close contact with an enclosed inert gas is lethal because it flushes oxygen from the body, but released into the open air, it quickly disperses, and is safe for others. It is neither flammable nor explosive. Close contact with the gas is achieved in Humphry's book by enclosing the head in a suicide bag

Dr Nitschke said the suicide device will prolong the lives of the terminally ill by making them feel in control of their future. "That idea of giving people access to a means of feeling that they're back in control of this issue is actually a way of prolonging life. It may seem paradoxical, but what we find is when people feel that they're back in control, they're less likely to do desperate things in desperate ways and people are always doing desperate things in desperate ways and ending their lives."
