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.

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.

The example method further includes determining whether blood is spontaneously flowing through the body of the subject by comparing the blood flow through the artery and the blood flow through the vein.

Abstract: An example method is performed by a first medical device and includes generating first data indicating a physiological parameter of a subject; generating a filter configured to remove an artifact associated with a treatment; and generating second data by applying the filter to the first data. The example method further includes determining that a second medical device is administering the treatment to the subject. In response to determining that the second medical device is administering the treatment to the subject, the first medical device outputs an indication that filtering is available; receives an input signal selecting the filtering; and in response to receiving the input signal, displays the second data.

Abstract: A prehospital telemedicine system comprises a physiologic monitor; an electronic patient care reporting system (ePCR) system; and a point-of-care blood analyzer communicatively coupled to the physiologic monitor and the ePCR system. The point-of-care blood analyzer is configured to perform an analysis of a blood sample based on an indication of a need for a specific blood analysis provided by one of the physiologic monitor and the ePCR system, and to automatically transmit a result of the analysis to a remote data receiving system. The indication of a need for a specific blood analysis may be based upon any one of the following: vital signs data obtained for a patient by the physiologic monitor; and/or current documentation or past medical history captured on or available through the ePCR system.

Abstract: An external defibrillator system is configured with at least two different algorithms for determining the duration of a shock administered to a patient being treated and selects the algorithm based on one or more patient parameters such as, for example, the patient's TTI. The patient's TTI can be measured prior to or while the shock is being administered to the patient. The shock can be, for example, a multiphasic defibrillation or a multiphasic cardioversion shock. The charge voltage of the system's energy storage device can additionally be varied depending on the one or more patient parameters. For example, the system may charge the energy storage device so that the charge voltage is higher or lower than a nominal charge voltage responsive to the patient's TTI is higher or lower compared to an average TTI, respectively.
