A system and method provide real-time detection of return of spontaneous circulation (ROSC) during cardiac arrest using at least one Doppler ultrasound patch with a pulsed-wave or continuous wave ultrasound transducer that emits an ultrasound beam into a subject's skin over a carotid, femoral, or brachial artery and receives at least one Doppler return signal indicative of blood flow. A fixation mechanism secures the transducer in a fixed position relative to the carotid, femoral, brachial artery, and a wired or wireless communication interface transmits the Doppler return signal to a processing unit. The processing unit receives and analyzes the Doppler return signal using a Doppler-Integrated Cardiac Arrest Flow Analysis (DICAF) algorithm, which uses a machine learning model trained on annotated Doppler waveform datasets to detect a first blood flow pattern generated by chest compressions and a second blood flow pattern generated by intrinsic cardiac activity. The system determines ROSC in real time and generates an alert for the user. The system can also monitor the quality of blood flow generated by chest compressions to guide cardiopulmonary resuscitation.

The system, devices, and method described herein may improve the outcomes of cardiac arrest patients being treated with CPR. The improvement is the result of enhancing intrathoracic pressure both during the chest compressions or constrictions as well as the relaxations. The enhancement is achieved by synchronizing low-volume inflations of the lungs with each chest compression and low-volume deflations with each chest relations. The high rate and fidelity of these ventilations are achieved by a unique multichannel endotracheal tube that uses high press oxygen and vacuum at its distal tip to administer and remove low-volume ventilations at the high rates of CPR compressions and relaxations. The synchronized oscillations of the airway pressure are transmitted physiologically to the intrathoracic space and augment forward blood flow. The system, devices, and method incorporate measurement of airway pressure and biomarker feedback control loops so as to avoid over pressurization or over depressurization of the lungs.

Cardiac arrest (CA) and traumatic brain injury (TBI) are critical medical events associated with high mortality and long-term disability, primarily due to ischemia and subsequent inflammation. Targeted temperature management (TTM), particularly hypothermia, has proven beneficial in reducing cell death, preserving brain function, and mitigating inflammation following these events. Conventional TTM methods are limited by delayed temperature reduction, poor temperature maintenance, and risks such as thromboembolism. The present invention addresses these challenges by introducing novel devices, apparatus, and systems for extracorporeal whole blood cooling, enabling rapid, controlled induction and maintenance of therapeutic hypothermia. By efficiently cooling the patient's whole blood volume outside the body, the method of the present invention offers a safer, more effective alternative to traditional methods, significantly improving patient outcomes after events such as CA and TBI. The present invention represents a promising advancement in emergency and critical care, enhancing survival and neurological recovery in severely ill patients.
