Method and auxiliary device of determining cardiopulmonary resuscitation quality parameters during process of cardiopulmonary resuscitation

Abstract

The invention discloses a method and an auxiliary device of determining cardiopulmonary resuscitation quality parameters during the process of cardiopulmonary resuscitation. The auxiliary device comprises an incentive module, a signal collection module and a signal processing module. The incentive module is used for exerting an incentive signal on a target object. The signal collection module is used for collecting a responding signal produced by the target object to the incentive signal. The signal processing module is used for analyzing and collecting the responding signal to obtain a direct current component and an alternating current component of the signal processing module, and is used for analyzing and calculating the cardiopulmonary resuscitation quality parameters of the target object according to the direct current component and the alternating current component. According to the method and the device of determining the cardiopulmonary resuscitation quality parameters during the process of cardiopulmonary resuscitation, the incentive signal is exerted on the target object, the responding signal produced by the target object thoracic impedance when responding to the incentive signal is detected, analysis and calculation are carried out according to the responding signal, so that the parameters related to the cardiopulmonary resuscitation quality is obtained. Therefore, the whole quality of the cardiopulmonary resuscitation can be known in real time and cardiopulmonary resuscitation measure can be adjusted in time according to the parameters to achieve the perfect cardiopulmonary resuscitation effect.

Description

technical field [0001] The patent of the present invention relates to the field of medical devices, in particular to a method for determining at least one quality parameter of cardiopulmonary resuscitation and auxiliary equipment for monitoring the quality of cardiopulmonary resuscitation. Background technique [0002] Cardiopulmonary resuscitation (CPR) is the key measure for rescuing critically ill patients with cardiac and respiratory arrest, that is, chest cardiac compression forms a temporary artificial circulation and restores spontaneous pulse, artificial / mechanical ventilation instead of spontaneous respiration, rapid electrical defibrillation First aid techniques for conversion of ventricular fibrillation and early restoration of spontaneous circulation with vasoactive drugs. The purpose of CPR is to open the airway and restore breathing and circulation. Cardiopulmonary resuscitation mainly includes chest compressions and artificial ventilation. Chest cardiac comp...

Problems solved by technology

[0003] In current clinical practice, chest compressions are generally done manually, and manual compression is the most effective compression method in a short period of time. However, manual compression has the following disadvantages: 1) It is difficult to master the frequency and depth of chest compressions, even for professionals. , and it is difficult to achieve a constant and efficient ideal compression; 2) Chest compression consumes a lot of energy and is prone to fatigue. In order to ensure the quality of compression, medical staff must switch between compression duties every two minutes, resulting in interruption of compression; 3) During the transportation of patients And some special places are difficult to carry out manual pressing

However, no matter whether it is performed manually or by mechanical equipment, there are problems in the resuscitation process because there is no monitoring or no objective indicators reflecting the actual compression quality, so that the best cardiopulmonary resuscitation effect cannot be achieved, which seriously affects success rate of cardiopulmonary resuscitation
