Cable loop detection mechanism for improved MRI safety

The following relates generally to ensuring patient safety while operating a Magnetic Resonance Imaging (MRI) machine. Many MRI systems operate using: fiber optic cables to carry signals, electrically conductive cables to carry other signals, and radio frequency (RF) coils to create an electromagnetic field. Typically, the electrically conductive cables and RF coils do not interact in a way that causes harm to a patient. However, certain shapes and/or lengths of cables exhibit the phenomenon of “resonance” that increases their propensity to concentrate RF currents induced by the RF coils. This may increase the temperature of the cable or other component in the MRI system leading to patient harm. The methods disclosed herein provide a solution to this by sensing a shape of the fiber optic cable and determining if the fiber optic cable will exhibit resonance. If it is determined that resonance may potentially occur, an alarm may be generated or a radio frequency amplifier may be interlocked.

Method and system for electrode impedance measurement
11337633 · 2022-05-24 · ·

The present invention relates to measuring electrical impedance, and particularly to measuring impedance of electrodes used to acquire physiological signals. The measurement of electrode impedance is typically performed to ensure proper electrode-to-skin contact, and thus verify the quality of the acquired signals. Electrode-to-skin contact impedance has also clinical utility for monitoring, diagnosis, prognosis or treatment, as it can be used to measure skin conductivity, which is function of physiological processes. The present invention relates in particular to a substantially continuous method for performing such measurement. The measurement is performed in such a way that it does not affect the bioband, the range (or ranges) of frequencies that contains components used for diagnostic, prognostic, triage, and/or treatment purposes. The present invention therefore performs this impedance measurement without affecting the physiological signal while allowing for uninterrupted monitoring of said signal.

Reversal of general anesthesia by administration of methylphenidate, amphetamine, modafinil, amantadine, and/or caffeine

The present invention generally relates to compositions comprising anesthesia-reversing agents which facilitate or increase the time of awakening or reverse the effects of general anesthesia-induced unconsciousness. In some embodiments, the anesthesia reversing agent can be selected from any or a combination of methylphenidate (MPH), amphetamine, modafinil, amantadine, caffeine, or analogues or derivatives thereof. In some embodiments, compositions comprising at least one or more anesthesia-reversing agents can be used to facilitate awakening from anesthesia without or decreasing occurrence of delirium, and can be used in methods to treat or prevent the symptoms associated with emergence delirium, as well as treat a subject oversedated with general anesthesia. The invention also relates to methods for administering these compositions comprising anesthesia-reversing agents to subjects and for use.
