Abstract: 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.

Abstract: A method of determining one or more diagnostic metrics to assess a blood vessel using intravascular data includes: sampling a sensor of an intravascular data collection probe disposed in the blood vessel during a pullback of the intravascular data collection probe through the blood vessel to obtain sampled distal pressure (Pd) values; receiving, at an intravascular data processing system, the sampled distal pressure (Pd) values and proximal pressure (Pa) values; determining sets of Pd/Pa ratios, each set including Pd/Pa ratios that are determined through an entirety of one heart cycle; determining minimum Pd/Pa ratios, each of which is a minimum within one of the sets of Pd/Pa ratios over the entirety of the corresponding heart cycle; and controlling a display system to generate a plot of a moving average of the minimum Pd/Pa ratios over time during the pullback.

Abstract: A device is for estimating the central blood pressure of a subject. The device comprises a sensor patch comprising an array of sensors configured to measure an indication of the blood pressure of a peripheral blood vessel and perform ultrasound imaging of the peripheral blood vessel. The device also comprises a processor configured to obtain a peripheral pressure signal comprising a pressure waveform from the indication of the blood pressure from the sensor patch and derive an image of the peripheral blood vessel from the signals received from the sensor patch. A vessel diameter is determined from the image of the peripheral blood vessel over time comprising a vessel diameter waveform and an estimate of the central blood pressure of the subject is derived from the pressure waveform and/or the vessel diameter waveform.

Abstract: Systems, devices, and methods for controlling intravascular data acquisition are provided. For example, a co-registration process can be used to control the start and/or stop of intravascular data acquisition. In one embodiment, a system includes a processor circuit configured to generate a roadmap of the vessel, identify a region of interest of the vessel on the roadmap, determine whether the intravascular data acquisition device has entered the region of interest, and control the intravascular data acquisition device to obtain intravascular data of the region of interest. The processor can then output, to a display device, a graphical representation of the intravascular data of the region of interest.

Abstract: Embodiments include a system for determining cardiovascular information for a patient. The system may include at least one computer system configured to receive patient-specific data regarding a geometry of the patient's heart, and create a three-dimensional model representing at least a portion of the patient's heart based on the patient-specific data. The at least one computer system may be further configured to create a physics-based model relating to a blood flow characteristic of the patient's heart and determine a fractional flow reserve within the patient's heart based on the three-dimensional model and the physics-based model.
