An example method is performed by a computing device executing instructions stored in data storage, and includes receiving physiologic monitoring data from a plurality of sensors coupled to a patient, receiving information indicating a measurement of patient motion during the patient care event, determining whether the measurement of patient motion is above a threshold, based on determining whether the measurement of patient motion is above the threshold, generating, for the physiologic monitoring data, a respective quality indicator, analyzing, by the computing device, (i) a combination of the physiologic monitoring data from the plurality of sensors and (ii) the respective quality indicator for the physiologic monitoring data to generate a response dependent upon the combination of the physiologic monitoring data as weighted by the respective quality indicator, and based on analyzing, outputting caregiver feedback by the computing device according to the response.

Methods and systems for patient parameter fusion and feedback

Internal bleeding systems, devices, and methods are disclosed that include a sensing module and a processing module. The sensing module has an ultrasound module and a communication module. The ultrasound module emits and receives ultrasound energy to and reflected from tissue in a patient and generates a reflected energy signal. The communication module transmits the reflected energy signal to the processing module. The processing module analyzes the reflected energy signal to determine if it indicates the presence of blood from internal bleeding in the patient.

Internal bleeding detection, assessment and monitoring devices, systems and methods

Light-based non-invasive blood pressure measurement systems and methods that include a sensor having a light emitter and a light detector are disclosed. The light emitter emitting coherent or non-coherent light that is transmitted into and reflected from the tissues of the patient, including reflecting from moving blood. The light reflected from the moving blood being having a Doppler shift and detected by the light detector to generate a noninvasive blood pressure signal. The non-invasive blood pressure signal is processed to determine the instantaneous velocity of the blood. Additionally, pulse wave velocity data is obtained nearly, or substantially, simultaneously with the acquisition of the non-invasive blood pressure signal. Using the pulse wave velocity, the instantaneous velocity of the blood and a density of the blood, an instantaneous blood pressure can be determined.

Light-based non-invasive blood pressure systems and methods

The disclosed non-invasive blood pressure systems and methods measure a patient's blood pressure without restricting blood flow. Other sensors, such as physiological sensors, sensors that sense data about the NIBP system components, and/or environment sensors sense data that is combined with the NIBP signal. The combined NIBP and sensor signals are used to measure a patient's non-invasive blood pressure.

Patient monitoring and treatment systems and methods

Non-invasive blood pressure (NIBP) systems and methods are disclosed that measure a blood pressure, and in some examples a beat-to-beat blood pressure, of a patient without restricting blood flow. The NIBP systems determine an efficacy of administered cardiopulmonary resuscitation (CPR) to the patient based on the measured blood pressure and are able to optionally output the CPR efficacy or generate user prompts based on the CPR efficacy. Further, the disclosed NIBP systems can generate user instructions to administer further treatment to the patient based on the CPR efficacy.

A method and apparatus to non-invasively measure instantaneous blood pressure using pulse wave velocity are disclosed. A measurement component is affixed to a patient proximate to a blood vessel. One or more sensors, such as an ultrasound sensor, is included in the measurement component. The measurement component substantially simultaneously measures the pulse wave velocity of the vessel and the instantaneous blood velocity within the vessel. The measurement component computes the instantaneous blood pressure of the vessel using, for example, the water hammer equation. The one or more sensors may be contained in a disposable patch or collocated with another sensor, such as a patient-monitor sensor, or the like.

Non-invasive blood pressure measurement using pulse wave velocity

Power supplies for electronic devices (e.g. medical imaging devices) are disclosed herein. In one embodiment, a switched mode power supply is minimized in size and weight while maintaining efficiency and an artifact-free image using power supply design techniques tailored to increasing the power conversion frequency to be above the desired receive band of an ultrasound imaging system. In another embodiment, a switched mode power supply is minimized in size and weight while maintaining efficiency and an artifact-free image using power supply design techniques tailored to increasing the power conversion frequency to be just below the desired receive band of an ultrasound imaging system causing the third harmonic and possibly the second harmonic to fall just above the desired receive band.

Low-noise power sources for imaging systems

The disclosed devices, systems and methods measure non-invasive blood pressure in a patient. Energy emissions, such as ultrasound or light, are emitted into tissues of the patient. The emitted energy reflects from various tissues, such as flowing blood and vessels, and can be detected, or received, to generate a reflected energy signal or data. The reflected energy can be processed, such as by using a constitutive equation, to calculate the blood pressure.

The light reflected from the moving blood being having a Doppler shift and detected by the light detector to generate a non-invasive blood pressure signal. The non-invasive blood pressure signal is processed to determine the instantaneous velocity of the blood.

A scan head for an ultrasound imaging device has a body that encloses a number of ultrasound transducers and controlling electronics. The electronics are sealed in the body of the scan head. The scan head has a fan that is configured to remove heat caused by the operation of the electronics. The motor is magnetically controlled and has controlling electronics that are sealed in the body of the scan head. In one embodiment, an airflow channel surrounds the electronics in the scan head and the fan is configured to move air through the airflow channel. In another embodiment, the electronics are thermally coupled to a heat exchanger heat via a conductive substrate and the fan is configured to move air over the heat exchanger.
