Problems solved by technology

[0006] However, the current automated chest compression devices operate under the pre-set compression depth, compression frequency and compression force, and cannot adjust the parameters according to the individual differences of patients, let alone dynamically adjust the compression parameters based on the real-time physiological information of the human body Therefore, how to implement accurate and efficient chest compressions according to the individual differences of patients is the key to the development of CPR devices

Embodiment 1

[0042] PETCO 2 It is an important physiological parameter for non-invasive monitoring of cardiopulmonary function, which can reflect the cardiopulmonary function during chest compressions in real time and objectively evaluate the return of spontaneous circulation (ROSC). However, PETCO has not yet 2It is organically combined with an automated chest compression device to form a closed-loop control system to realize a fully automatic parameter-adjustable chest compression device based on real-time cardiopulmonary function feedback.

[0043] Therefore, how to solve the problem of PETCO 2 The analysis and information feedback of monitoring results are technical problems to be solved at present. Studies have shown that patients who can successfully perform CPR have the lowest PETCO before ROSC 2 It needs to be greater than 10mmHg, if it is lower than this value, patients often cannot achieve ROSC; when PETCO 2 When it is greater than 20mmHg, the probability of successful resusc...

Abstract

The invention discloses a PETCO2-based auxiliary control method and system for an external chest compression device, and the control method comprises the steps: determining a difference value signal according to a compression depth tracking difference value, a compression frequency tracking difference value and changes thereof; according to the difference value signal and the previous PETCO2, determining the actual current PETCO2; determining a control signal based on a difference value between the target value of the PETCO2 and the actual current PETCO2; and adjusting the compression depth and the compression frequency of the external chest compression device based on the control signal. The PETCO2 and the automatic external chest compression device are organically combined into closed-loop control, so that full-automatic adjustment of external chest compression parameters based on real-time cardiopulmonary function feedback is realized.

Description

technical field [0001] The invention relates to the technical field of cardiopulmonary resuscitation equipment, in particular to a PETCO-based 2 An auxiliary control method and system for a chest compression device. Background technique [0002] The statements in this section merely provide background information related to the present invention and do not necessarily constitute prior art. [0003] Cardiopulmonary resuscitation (CPR) helps patients recover spontaneous circulation during cardiac arrest, helps reduce organ damage caused by tissue hypoxia, and improves survival rates. Existing CPR mostly adopts manual operation mode, and there are many problems. [0004] First of all, freehand chest compressions consume a lot of physical strength for the rescuers, and it is difficult to achieve effective chest compression standards. If the rescuers are fatigued or frequently changed, the compression quality will be unstable and affect the recovery effect. Secondly, it is dif...
