How is determination of death decided? What is the law on the criteria of death?

Regulations of the Act provide clear and comprehensive instructions on how confirmation of patient death should be confirmed. This includes a cerebral angiography of the brain – this is an X-ray that shows that there is no longer a blood supply a to the brain. The brain is then said to be irreparably damaged (also known as brain death). When all requirements are met, a death certificated is issued and signed by two doctors. At this point, death is determined as certain.
