Abstract: The present disclosure is directed to apparatuses, systems and methods for measuring time-varying radar cross section (RCS) of an artery of a patient, which may be used to determine blood pressure of a patient. In some embodiments, an apparatus is provided which comprises a radio-frequency (RF) transceiver for generating RF waves, and at least one sensor configured for positioning on or adjacent the skin of a patient, and at least one of transmitting the RF waves into tissue of the patient and receiving RF wave reflections from at least one artery located within the tissue. The apparatus may further comprise a processor having computer instructions operating thereon configured to cause the processor to determine an RF arterial pulse waveform based on the received RF wave reflections. The time-varying radar cross section (RCS) comprises the RF arterial pulse waveform. This may be in turn correlated to blood pressure of the patient.

Abstract: Some embodiments of the current disclosure are directed toward physiological monitoring of patients, and more particularly, systems, devices and methods for physiological monitoring of patients with a continuous or near-continuous transmission and analysis of monitored physiological data during the monitoring process. In some embodiments, a physiological patient monitoring system is provided which includes a physiological monitoring device which comprises a housing disposed on a patch, and the patch is configured for removable attachment to or proximate the skin of a patient, the housing including at least one memory. Antenna disposed on the housing transmit radio-frequency (RF) waves towards a targeted portion of an internal tissue of the patient and receive reflected RF waves from the internal tissue. RF circuitry in communication with the at least one memory perform an RF-based measurement of a lung fluid level of the patient during a predetermined time period.
