摘要： A patient monitoring system includes a capacitive electrode connectable to a patient to detect an output signal and a signal generator unit that transmits a carrier signal to the capacitive electrode, the carrier signal having a carrier frequency and a carrier amplitude. The patient monitoring system further includes an amplifier unit that amplifies the output signal detected by the capacitive electrode to generate an amplified output signal. A gain determination module in the patient monitoring system determines an output amplitude of a carrier frequency portion of the amplified output signal, and determines a system gain based on a comparison between the output amplitude and the carrier amplitude. A voltage determination module in the patient monitoring system filters the output signal to isolate a physiological signal detected from the patient, and determines a voltage of the physiological signal based on the system gain.

摘要： Medical devices and methods in which a user can treat a patient or monitor a parameter of the patient or both may include a housing, a patient module located within the housing that is used for treating the patient, monitoring the patient or both, and a control panel. The control panel is attached to the housing and has a first surface and a second surface and is positionable between a first position and a second position with respect to the housing. The first position exposes a user to a first surface of the control panel and the second position exposes the user to a second surface of the control panel. A first set of user controls are located on one or the other of the first surface and the second surface and are structured to allow the user to interact with the patient module.

摘要： A wearable cardioverter defibrillator (“WCD”) system may include an impedance detector configured to render an impedance signal of the patient. The WCD system may determine, from the impedance signal, a characteristic of breathing by the patient that can be used as a vital sign. The WCD system may determine, from at least the breathing characteristic, whether or not a shock criterion is met. If the shock criterion is met, the WCD system may control a discharge circuit to discharge a stored electrical charge through the patient. An advantage can be that the breathing characteristic may be used to determine whether or not a patient is experiencing a condition that requires defibrillation therapy, such as sudden cardiac arrest. Even more advantages can be had in discerning the state of the patient when the breathing characteristic is combined with other data, such as from a motion detector.

摘要： An extra-cardiovascular implantable cardioverter defibrillator senses R-waves from a first cardiac electrical signal by a first sensing channel and stores a time segment of a second cardiac electrical signal in response to each sensed R-wave. The ICD determines intervals between successively sensed R-waves and, in response to at least a predetermined number of the intervals being less than a tachyarrhythmia detection interval, analyzes at least a portion of the time segment of the second cardiac electrical signal corresponding to a most recent one of the sensed R-waves to confirm the most recent one of the R-waves. The ICD updates an unconfirmed beat count in response to the most recent one of the R-waves not being confirmed and withholds detection of a tachyarrhythmia episode in response to the unconfirmed beat count being equal to or greater than a rejection threshold.

摘要： A computing device includes a memory configured to store instructions. The computing device also includes a processor to execute the instructions to perform operations that include providing an alternating electrical signal to a patient through at least a pair of electrodes, and determining transthoracic impedance of the patient from a measurement associated with the applied alternating electrical signal. Operations also include identifying, from the transthoracic impedance, a sequence of resistance values for controlling the discharge of a charge storage device located external to the patient, and controlling the discharge of the charge storage device using the identified sequence of resistance values.

摘要： The presence of a cardiac pulse in a patient is determined by evaluating fluctuations in an electrical signal that represents a measurement of the patient's transthoracic impedance. Impedance signal data obtained from the patient is analyzed for a feature indicative of the presence of a cardiac pulse. Whether a cardiac pulse is present in the patient is determined based on the feature in the impedance signal data. Electrocardiogram (ECG) data may also be obtained in time coordination with the impedance signal data. Various applications for the pulse detection of the invention include detection of PEA and prompting PEA-specific therapy, prompting defibrillation therapy and/or CPR, and prompting rescue breathing depending on detection of respiration.

摘要： Medical devices, plug-ins, systems, and methods for CPR quality feedback are disclosed. The medical devices can calculate peripheral circulation relevant parameters based on measured signals containing at least partial hemodynamic characteristics. Amplitude and area characteristics included in the peripheral circulation relevant parameters can further be determined for providing feedback and control relating to CPR quality during the compression process. Also, compression interruption during CPR can be evaluated based on a pulse waveform generated from the measured signals.

摘要： A defibrillator with wireless communications with a patient monitor. The wireless communications transmits patient data collected by measurement modules between the defibrillator and the patient monitor using wireless nodes when a patient is under cardiac arrest. The transmitted data is integrated with the data already residing on each respective device using data integration modules, and then displayed to the code team in the patient's room on displays, thereby allowing every member of the code team to see data from both devices by reading just one of the displays. The integrated data is also associated with synchronized clocks between the two devices. The integrated data is then compiled into a single unified report comprising the data from both devices and attached to the patient's electronic health record located on a patient record database.
