These are the baseline criteria required to ensure a peaceful and reliable death to the user inside.
One important aspect of the testing regime was for the creator of the Sarco, Philip Nitschke, to experience for himself the feel of the operation of the Sarco from within.
In May 2024, Philip wore oxygen-fed nasal prongs. He lay in the Sarco, pressed the green activation button and experienced, for himself, the flow of the nitrogen gas.
After this experiment he reported that sensation of the entry of the gas into the capsule was barely noticeable.
He said he could well imagine the peace of mind that a beautiful view out the window of the Sarco could provide.
