Problems solved by technology

However, most of the traditional detection methods are currently used in clinical practice: (1) After judging the loss of consciousness in the physical examination, the carotid artery fluctuations disappear and there is no breathing by hand-touch detection, that is, it is judged as a pulseless state. There are nearly 50% misdiagnosis of pulse detection by touch, and the use of pressure, infrared, laser, photoplethysmography (PPG) and other methods can only measure the number of pulses, and cannot measure the real situatio

[0023] According to the first embodiment of the present invention, a PEA detection method for pulseless electrical activity is provided, including: detecting the electrical activity signal of the heart, detecting the blood flow signal of the common carotid artery, and determining based on the electrical activity signal of the heart and the blood flow signal of the common carotid artery Pulseless electrical activity PEA.

[0024] Although there are some differences between false PEA and true PEA in clinical ECG, the identification process of PEA is often ignored in the monitoring process. The regular narrow QRS and slow wide QRS are difficult to judge with the naked eye, or can only rely on the treatment experience and waiting time. Judgments can only be made based on the familiarity of the patient's body data; in addition, the hospital usually avoids touching the periphery of the body when treating intensive care patients, so it is impossible to pay timely attention to the occu...

Abstract

A pulseless electrical activity (PEA) detection method comprises the steps of: detecting a heart electrical activity signal, detecting a common carotid artery blood flow signal, and judging PEA based on the heart electrical activity signal and the common carotid artery blood flow signal. Meanwhile, common carotid artery blood flow parameters and electrocardiosignals serve as factors for comprehensively evaluating the PEA; the electrocardiosignals and blood flow signals associated with the electrocardiosignals in time can be analyzed in real time; the accuracy of PEA judgment based on the basis is high; time delay is small; besides, an ultrasonic Doppler blood flow detection module is used for testing the real condition of blood flow; hand touch type or induction type pulse measurement is replaced; the measurement result is real; and PEA judgment can be more effectively assisted.

Description

technical field [0001] The present invention relates to the technical field of medical detection equipment, in particular to a PEA detection method and device for pulseless electrical activity. Background technique [0002] PEA (Pulseless electrical activity), that is, pulseless electrical activity, also known as electromechanical dissociation, generally refers to the normal electrical activity of the heart, but there is no corresponding mechanical activity, unable to generate enough blood pressure to touch the arterial pulse. In patients with cardiac arrest, the incidence of PEA is gradually increasing, while the success rate of PEA rescue is very low. [0003] PEA is usually divided into two categories: one is true PEA, which means that the heart does not have any mechanical contraction function and cannot produce any arterial pulse; the other is pseudo-PEA, which means that the heart has certain mechanical activities, but due to other reasons, The mechanical activity is ...
