Cardio-pulmonary resuscitation monitoring method and system

Abstract

The invention provides a cardio-pulmonary resuscitation monitoring method and a cardio-pulmonary resuscitation monitoring system. The cardio-pulmonary resuscitation monitoring method comprises the following steps: in the external chest compression process, a defibrillation electrode acquires thoracic impedance signals of a patient responding to exciting signals, wherein the exciting signals are multiple paths of independent oscillating signals, the thoracic impedance signals are treated by adopting a pre-stored extreme value search algorithm, then separate compression waves and vent waves are obtained, the current data of the thoracic impedance signals, the compression waves and the vent waves are read, calculation is carried out on the current data, and then relevant parameters of the current quality of the cardio-pulmonary resuscitation are obtained and displayed, so that workers are guided to carry out the correct external chest compression on the patient, thus the quality of the cardio-pulmonary resuscitation is guaranteed, and the success rate in rescuing the patients with sudden cardiac arrest is improved; and in addition, an additional device does not need to be arranged on the body of the patient, so that the structure of the system and the monitoring steps are simplified.

Description

technical field [0001] The present invention mainly relates to the field of medical instruments, and more specifically relates to a cardiopulmonary resuscitation monitoring method and system. Background technique [0002] At present, cardiopulmonary resuscitation (CPR) is the only effective way to rescue patients with cardiac arrest, which mainly includes basic life support (Basic Life Support, BLS) such as chest compressions, artificial ventilation, and external defibrillation. The most commonly used CPR method, its quality is closely related to compression depth, compression frequency and chest rebound degree, etc., especially sufficient compression depth, which is the key to maintaining a certain coronary perfusion pressure (Coronary Perfusion Pressure, CPP), and CPP is At present, it is the most direct index to predict whether the return of spontaneous circulation (ReturnOfSpontaneousCirculation, ROSC). Therefore, in practical applications, the quality of cardiopulmonar...

Problems solved by technology

[0003] However, the existing CPR quality detection is usually implemented in an invasive way, which cannot be widely used, and the monitoring of chest compressions needs to add acceleration sensors or displacement sensors on the patient's chest to obtain compression depth and frequency parameters, in order to ensure accurate monitoring degree, which makes the monitoring structure complex and the monitoring steps cumbersome
