  • Publication number: 20240261584
    Abstract: Implementations for detecting blood flow through one or more blood vessels of a patient may include a flow monitor suited to detect blood flow to the brain during emergency situations. The flow monitor may be disposed on the skin of a patient and may emit an incident beam (e.g., ultrasound and/or infrared light) at an angle that is non-parallel to the blood vessel(s). The flow monitor may determine the velocity of blood flowing through the blood vessel(s) by detecting a Doppler shift in a reflection of the incident beam from the blood.

  • Publication number: 20240261179
    Abstract: Systems, devices, and methods for determining a condition of a subject during cardiopulmonary resuscitation (CPR) are described herein. In an example method, a measurement of a physiological parameter of an individual is filtered and/or gated based on identifying a treatment administered to the individual. A condition of the subject is identified based on filtering and/or gating the physiological parameter. The example method can be implemented into a mechanical chest compression device or another portable medical device. Together, the methods can improve the monitoring and treatment of subjects receiving CPR.

  • Patent number: 11998340
    Abstract: The system and method provide for electrocardiogram analysis and optimization of patient-customized cardiopulmonary resuscitation and therapy delivery. An external medical device includes a housing and a processor within the housing. The processor can be configured to receive an input signal for a patient receiving chest compressions and to select at least one filter mechanism and to apply the filter mechanism to the signal to at least substantially remove chest compression artifacts from the signal. A real time dynamic analysis of a cardiac rhythm is applied to adjust and integrate CPR prompting of a medical device. Real-time cardiac rhythm quality is facilitated using a rhythm assessment meter.

  • Publication number: 20240065576
    Abstract: Systems and methods described herein relate to determining physiological parameters and associated reliability of the physiological parameters and displaying the data in a manner that conveys the reliability information to a user. The reliability index is determined and then used to determine one or more display attributes for displaying the underlying parameter data while also conveying the reliability information. The implementations described herein provide for displaying physiological parameters in a manner that is easily digested and understood while also conveying a reliability in such data, without filling or cluttering a display with background or additional data that is typically used in a manual method to evaluate the data on the display.

  • Patent number: 11844607
    Abstract: A capnograph system may be used together with a ventilation system for a patient. The capnograph system may include a capnography module with a carbon dioxide detector, which may generate a carbon dioxide signal responsive to an amount of carbon dioxide detected within an air path of the ventilation system. A monitoring circuit may further detect a pressure within the air path. A processing component within the capnography module may generate a pressure signal responsive to the pressure detected in the air path. The pressure signal, alone or in combination with other signals such as the carbon dioxide signal, may be used to detect spontaneous breaths of the patient.
