Patent number: 11006865Abstract: Portable automated systems and methods can be used to perform field testing of patient blood chemistry to determine whether biological death has occurred in a clinically dead patient, and therefore whether the patient is a viable candidate for resuscitation efforts. A blood sample is received in a detector, which analyzes the blood sample to generate a signal representing at least one blood chemistry parameter of the blood sample and transmits a signal representing the at least one blood chemistry parameter to a processor. The processor compares the at least one blood chemistry parameter to a corresponding at least one resuscitatability parameter and, based on the comparison, causes an indicator to emit a resuscitatability indicator signal indicating potential resuscitatability, such as “resuscitatable”, “non-resuscitatable” or “borderline”/“indeterminate”.Type: GrantFiled: December 7, 2016Date of Patent: May 18, 2021Inventor: Anthony Filice
