Abstract: Described are a device and method for detecting cerebral perfusion in a subject's head during a cardiac crisis. Embodiments of the device include a neurological status evaluation apparatus having a signal generator configured to generate an electromagnetic signal at one or more frequencies, a transmitting antenna coupled to the signal generator and configured to transmit the electromagnetic signal, and a receiving antenna positioned proximate to the transmitting antenna such that an evaluation space is defined between the transmitting antenna and the receiving antenna. In embodiments, the subject's head does not contact the transmitting antenna or the receiving antenna. The receiving antenna receives a modulated electromagnetic signal after propagating through the subject's head. The neurological status evaluation apparatus further includes a signal analyzer coupled to the receiving antenna, wherein the signal analyzer receives and samples the modulated electromagnetic signal.
