Example Embodiment

[0026] Example one:

Example Embodiment

[0027] Such as figure 1 As shown, an implementation of the pulse wave processing method of the present application includes the following steps:

[0028] Step 102: Process the measured signal, and the measured signal reflects the real-time pulse characteristics of the measured person. Which processes the measured signal, including:

[0029] Identify fluctuating components and constant components from the measured signal;

[0030] Generate pulse waves based on fluctuation components.

[0031] This application can establish a sliding time window, and display the pulse wave in the sliding time window.

[0032] Step 104: Perform pulse wave recognition according to the processing result.

[0033] In the state where the patient has not recovered the spontaneous circulation, high-quality chest compressions should be performed and interruptions should be minimized. Factors such as tracheal intubation or changing the press during manual compression often cause interruption of compression. The ...

Abstract

The invention provides a method and equipment based on pulse blood oxygen technology to monitor cardio-pulmonary resuscitation) pressing interruption time and discloses a pulse wave processing method. The pulse wave processing method includes: processing a tested signal which reflects realtime pulse characteristic of a test receiver; performing pulse wave recognition according to processing result; statistically analyzing pulse wave interruption time according to recognition result; outputting statistical information. The invention further discloses medical equipment for pulse wave processing. In a specific embodiment, the pulse wave interruption time is statistically analyzed according to the pulse wave recognition result, and the statistical information is output, so that medical staff can directly acquire the statistical information. Compared with the prior art in which pulse waves are judged by observing waveforms of the pulse waves through human eyes, the method has the advantages that information of the pulse wave interruption time can be displayed visually, and doctors can be reminded of paying attention to avoiding potential danger so as to increase cardio-pulmonary resuscitation success rate.

Description

technical field [0001] The present application relates to the medical field, in particular to a pulse wave processing method, device and medical equipment. 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 which manifest 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 vital organs. [0003] In the state of the patient without ROSC, high-quality chest compressions should be performed with as few interruptions as possible. In 2013, the American C...
