This article researches a relatively new suicide method advanced by right-to-die organizations: oxygen deprivation by breathing helium inside a plastic hood. The article begins with a review of the role of the coroner and the history of oxygen deprivation with helium; it then examines 20 Judgements of Inquiry (JOI) by British Columbia coroners into this form of suicide. The JOI were obtained through the Freedom of Information and Protection of Privacy Act and cover the period of 1999 to 2007. Findings raise concerns about the coding system used by coroners as well as adherence to internal documentation guidelines. The British Columbia Coroners Service (BCCS) has a public safety mandate to investigate all unnatural deaths and to make recommendations to prevent deaths in similar circumstances. It is a concern that BCCS has no recommendations to prevent suicides by oxygen deprivation with helium. More in-depth, systematic research is recommended to determine the prevalence of suicide by oxygen deprivation and to develop strategies to benefit public health and safety.
