Problems solved by technology

Although the guidelines propose that end-tidal carbon dioxide and invasive blood pressure monitoring can monitor the quality of cardiopulmonary resuscitation, it will inevitably lead to a certain degree of hyperventilation during manual compressions. This hyperventilation may not accurately reflect the quality of cardiopulmonary There may also be a certain degree of lag in the identification of the cycle. In addition, end-tidal carbon dioxide requires not only special equipment but also benchmark calibration, which is cumbersome and time-consuming. Moreover, invasive blood pressure monitoring also requires pressure reference calibration, so these two recommended methods are difficult to implement in practice

Embodiment Construction

[0045] For the purposes of promoting an understanding of the principles of the invention, reference will now be made to the exemplary embodiments illustrated in the drawings, and specific language will be used to describe the same.

[0046] Pulse Oximetry Fundamentals

[0047] The principle of blood oxygen saturation measurement includes two parts: spectrophotometry and blood volume. Spectrophotometry uses red light with a wavelength of 660nm and infrared light with a wavelength of 940nm, according to oxyhemoglobin (HbO 2 ) absorbs less red light at 660nm, but absorbs more infrared light at 940nm; on the contrary, hemoglobin (Hb) can determine the oxygen content of hemoglobin by measuring the ratio of infrared light absorption to red light absorption by spectrophotometry. The degree of fusion, that is, the blood oxygen saturation (SaO 2 ).

Abstract

The invention relates to real-time identification of restoration of spontaneous circulation (ROSC) in a cardio-pulmonary resuscitation (CPR) process, in particular to ROSC identification equipment for identifying ROSC in real time in the CPR process. The ROSC identification equipment comprises a signal acquisition device and a signal analysis device, wherein the signal acquisition device is used for acquiring a pulse blood oxygen wave signal of a patient, and the signal analysis device is used for analyzing the signal so as to determine whether the ROSC is recovered in the CPR process.

Description

technical field [0001] The present invention relates generally to identifying restoration of spontaneous circulation (ROSC), and more particularly to devices for identifying ROSC in real time during cardiopulmonary resuscitation (CPR), ROSC identification and quality assessment systems, and ROSC feedback control system during CPR. Background technique [0002] Cardiovascular disease has become the most important cause of human morbidity and death, causing approximately 17,000,000 deaths worldwide each year, many of them manifested as sudden cardiac death. Sudden cardiac death has become an important killer that threatens human life and health, and the most effective and direct medical method for this situation is cardiopulmonary resuscitation (CPR). CPR creates temporary artificial circulation by increasing pressure in the chest (chest pump mechanism) or directly squeezing the heart (cardiac pump mechanism) to create blood flow that delivers oxygen to the brain and other vi...
