Cases Without Cardiopulmonary Support

An optimal cryonics case is one in which a cryonics team is standing by at the moment the heart stops so that prompt cardiopulmonary support can be applied to keep the brain biologically viable after legal death. In some cases, however, it is not possible to restore or maintain blood circulation promptly after cardiac arrest. This results in more serious brain injury, but most cryonicists believe it is an ethical imperative to proceed with cryonics even under adverse circumstances as long as the line between life and death remains unclear from the perspective of future medical capabilties.
