The Sarco pod (also known as Pegasos and has been referred to as a "suicide pod"[1]) is a euthanasia device or machine consisting of a 3D-printed detachable capsule mounted on a stand that contains a canister of liquid nitrogen to die by suicide through inert gas asphyxiation. "Sarco" is short for "sarcophagus".[2][3] It is used in conjunction with an inert gas (nitrogen) which decreases oxygen levels rapidly which prevents panic, sense of suffocation and struggling before unconsciousness, known as the hypercapnic alarm response[4]: 45  caused by the presence of high carbon dioxide concentrations in the blood.[4] The Sarco was invented by euthanasia campaigner Philip Nitschke in 2017. Nitschke said in 2021 that he sought and received legal advice about the device's legality in Switzerland.[5]
