Synchronous defibrillation system and method for defibrillator-monitor

Abstract

The invention discloses a synchronous defibrillation system and method for a defibrillator-monitor. The method comprises the following steps: controlling an electro-cardio controller to rapidly perform R-wave identification on an obtained digital electro-cardio signal, and setting the level of a first hardware IO (Input / Output) port as a corresponding level when the extreme point of R-waves is identified; controlling a defibrillation controller to detect whether the level of a second hardware IO port is a corresponding level or not, judging whether the electro-cardio controller identifies the extreme point of the R-waves or not, and controlling a defibrillation relay to be started; controlling the defibrillator-monitor to discharge in order to perform high-voltage defibrillation on a patient when the defibrillation relay is started. According to the synchronous defibrillation system and method for the defibrillator-monitor, the level of the first hardware IO port is adopted as a corresponding level by adopting a hardware way to serve as a notification signal, and the defibrillator-monitor is controlled to perform high-voltage defibrillation on the patient, so that delay in synchronous defibrillation can be effectively reduced, the delay time of synchronous defibrillation is effectively controlled, and the risk is lowered.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to a defibrillation monitor synchronous defibrillation system and method. Background technique [0002] Ventricular fibrillation, abbreviated as ventricular fibrillation or ventricular fibrillation, is the most serious type of fatal cardiac arrhythmia; so far, electrical shock defibrillation is considered to be the most rapid and effective way to terminate ventricular fibrillation. Electric shock defibrillation is divided into synchronized defibrillation (synchronized defibrillation) and non-synchronized defibrillation (non-synchronized defibrillation) according to whether it is synchronized with the R wave. The general defibrillator supports both synchronous and non-synchronized defibrillation modes. [0003] During synchronous defibrillation, the current needs to be released in the descending branch of the R wave of the QRS wave of the patient's electrocardiogram or within 30 ms o...
