The following description will be given of the related terms related to the present application, as follows:

burst suppression ratio (burst suppression ratio, BSR): BSR is an indicator used to measure the degree of balance between burst and inhibition in an electroencephalogram signal. Burst is a high frequency oscillation in brain activity, while inhibition is a low frequency oscillation. BSR is commonly used to assess the characteristics of brain activity in conditions of anesthesia, coma, or epilepsy. After the electroencephalogram signal is divided into two phases of an outbreak period and a suppression period, calculating the ratio of the duration of the suppression period to the total duration, and thus obtaining the BSR. A higher BSR indicates more inhibitory activity, possibly associated with loss of consciousness or impaired brain function.

Spectral Coherence (COH): COH is an indicator for measuring the degree of signal synchrony between two brain regions. It can be evaluated by calculating the relationship between the phase and amplitude of the two signals in different frequency ranges. COH is often used to study functional connections and information transfer of neural networks, which can help us to understand the coordination mechanisms of the brain in different cognitive tasks.

Permutation entropy (Permutation Entropy, PE): PE is an index that describes signal complexity and irregularities. It measures the complexity of the signal by calculating the probability distribution of different permutation modes based on the permutation order of the signal values. In brain electrical signal studies, higher permutation entropy may represent more complex and flexible brain dynamics, associated with information processing and cognitive abilities.

Depth of anesthesia (Depth Of Anaesthesia, DOA): DOA refers to the extent to which the patient's consciousness, sensation and physiological response is inhibited during general anesthesia. General anesthesia is the loss of consciousness and sensation in a patient through the use of anesthetic drugs to perform surgery or other medical procedures. Assessment of the depth of anesthesia is important to ensure patient safety and comfort.

Wherein the plurality of anesthesia index parameters at least comprise a BSR parameter, a COH parameter and a PE parameter; each anesthesia index data set corresponds to an anesthesia index parameter; each anesthesia index parameter corresponds to an anesthesia index type identifier.

Specifically, anesthesia index data at the latest moment in a plurality of groups of anesthesia index data sets are used as corresponding anesthesia index parameters, namely BSR data at the latest moment in a BSR data set are used as BSR parameters, wherein the numerical range of the BSR parameters is 0-1, and anesthesia index type marks corresponding to the BSR parameters are BSR; taking COH data at the latest moment in the COH data set as COH parameters, wherein the numerical range of the COH parameters is 0-1, and the anesthesia index type corresponding to the COH parameters is identified as COH; and taking PE data at the latest moment in the PE data set as PE parameters, wherein the numerical range of the PE parameters is 0-1, and the anesthesia index type corresponding to the PE parameters is marked as PE.

And step S304, combining the plurality of anesthesia index parameters according to the case information to obtain target DOA parameters.

The case information comprises medical history information, and firstly, anesthesia index type identifiers corresponding to the medical history information are determined to obtain at least one anesthesia index type identifier; then, acquiring anesthesia index parameters with the same anesthesia index type identifier as the at least one anesthesia index type identifier from the plurality of anesthesia index parameters to obtain at least one anesthesia index parameter; finally, determining the target DOA parameter according to the at least one anesthesia index parameter.

Wherein determining the target DOA parameter according to the at least one anesthesia index parameter specifically comprises: acquiring a weight group corresponding to the medical history information, wherein the weight group comprises at least one weight, and the at least one weight corresponds to the at least one anesthesia index parameter one by one; and carrying out weighted operation according to the at least one weight and the at least one anesthesia index parameter to obtain the target DOA parameter.

The weighting operation is performed according to the at least one weight and the at least one anesthesia index parameter to obtain the target DOA parameter, which specifically comprises the following steps: performing weighted operation according to the at least one weight and the at least one anesthesia index parameter to obtain a reference DOA parameter; acquiring target hardware parameters and target software parameters of the anesthesia monitoring alarm equipment; determining a first influence coefficient corresponding to the target hardware parameter; determining a second influence coefficient corresponding to the target software parameter; and dynamically adjusting the reference DOA parameter according to the first influence coefficient and the second influence coefficient to obtain the target DOA parameter.

Specifically, firstly, according to the mapping relation between medical history information and anesthesia index type preset, the anesthesia index type identification needing to be concerned is determined, for example, if the target object suffers from a nervous system disease such as epilepsy, the COH parameter is needed to be used as an important index for evaluating brain function, and consciousness and brain function of the target object are closely monitored, so that any abnormal situation can be found and treated in time. Then, the anesthesia index parameters corresponding to the anesthesia index type identifier to be focused are obtained from the anesthesia index parameters, then the weight group corresponding to the medical history information is obtained, for example, the target brain injury, stroke or other nervous system diseases are required to be focused on the BSR parameters and the PE parameters, so that the safety of the patient in the operation process is ensured, the weights corresponding to the BSR parameters and the PE parameters are larger, namely, the weight corresponding to the BSR parameters is 0.35, the weight corresponding to the COH parameters is 0.30, and the weight corresponding to the PE parameters is 0.35. And carrying out weighted operation on at least one anesthesia index parameter and a corresponding weight to obtain a reference DOA parameter, obtaining a target hardware parameter and a target software parameter of the anesthesia monitoring alarm device, wherein the target hardware parameter comprises, but is not limited to, temperature, humidity and sensor sensitivity, the target software parameter comprises, but is not limited to, software version and algorithm selection, the first influence coefficient is determined according to a preset mapping relation between the target hardware parameter and the first influence coefficient, the second influence coefficient is determined according to a preset mapping relation between the target software parameter and the second influence coefficient, the reference DOA parameter is dynamically adjusted according to the first influence coefficient and the second influence coefficient, and the reference DOA parameter is multiplied by a coefficient with the value of 100 to obtain the target DOA parameter, wherein the numerical range of the target DOA parameter is 0-100.

Step S305, determining a target DOA threshold range corresponding to the case information.

Wherein the case information further includes personal information; the personal information includes: age information, height information, and weight information; firstly, acquiring a reference DOA threshold range corresponding to the personal information; determining a target body metabolic rate of the target object according to the personal information; then, determining a target metabolic rate of the target anesthetic drug based on the target body metabolic rate; determining the anesthesia depth influence degree parameters corresponding to the medical history information and the target anesthetic; and finally, adjusting the reference DOA threshold range according to the target metabolic rate and the anesthesia depth influence degree parameter to obtain the target DOA threshold range.

In particular, different target subjects have different needs and responses to the depth of anesthesia, wherein the differences between individuals may be related to age, height, weight, etc., and older target subjects may require shallower depth of anesthesia, while older target subjects may require deeper anesthesia, and height and weight may also have an impact on depth of anesthesia, with a greater range of reference DOA thresholds for higher or heavier target subjects.

Determining different target body metabolic rates according to the difference of the personal information, wherein:

male: 10 Xweight (KG) +6.25 Xheight (CM) -5 Xage +5

Female: 10 Xweight (KG) +6.25 Xheight (CM) -5 Xage-161

Thus, the corresponding reference DOA threshold range and target body metabolic rate are obtained according to personal information, meanwhile, different narcotics have different metabolic pathways and metabolic speeds, some narcotics are metabolized by the liver, and other narcotics may be metabolized mainly by the kidney or other pathways, so that the metabolic speed of each drug is different. Finally, comprehensively evaluating the characteristics of the target anesthetic and the target body metabolism rate to obtain the target metabolism rate. Further, determining the parameter of the influence degree of the anesthesia depth corresponding to the medical history information and the target anesthetic, wherein the medical history information influences the selection and the dosage adjustment of the anesthetic, thereby influencing the anesthesia depth, and different anesthetics have different pharmacological characteristics and metabolic pathways, and some drugs may have a longer half-life or obvious accumulation effect, which also causes the anesthesia depth to be influenced. Therefore, corresponding anesthesia depth influence degree parameters can be obtained, and the reference DOA threshold range is adjusted according to the target metabolic rate and the anesthesia depth influence degree parameters to obtain a target DOA threshold range.

Therefore, the target DOA threshold range is determined according to the personal characteristics and the target drug metabolism condition, so that anesthesia management is more personalized and accurate, the special condition of a target object can be better adapted, and the anesthesia effect and the safety of the anesthesia process are improved.

The reference DOA threshold range is adjusted according to the target metabolic rate and the anesthesia depth influence degree parameter to obtain a target DOA threshold range, and the method specifically comprises the following steps: firstly, a first lower threshold value and a first upper threshold value of the reference DOA threshold value range are obtained; determining a target regulation parameter corresponding to the target metabolic rate; then, the first lower limit threshold value and the first upper limit threshold value are adjusted according to the target adjustment parameter, so that a reference first lower limit threshold value and a reference first upper limit threshold value are obtained; determining a target fine tuning parameter corresponding to the anesthesia depth influence degree parameter; adjusting the reference first lower limit threshold according to the target fine tuning parameter to obtain a target first lower limit threshold; finally, the target DOA threshold range is determined according to the target first lower threshold and the reference first upper threshold.

Specifically, a first lower threshold and a first upper threshold of the reference DOA threshold range are obtained, and then a target regulation parameter corresponding to the target metabolism speed is determined, wherein the faster the target metabolism speed is, the faster the target anesthetic is metabolized and cleared, so that the reference DOA threshold range needs to be increased to ensure that the target object maintains a sufficient anesthetic effect in the anesthetic process. And then, adjusting the first lower limit threshold and the first upper limit threshold according to the target adjustment parameter to obtain a reference first lower limit threshold and a reference first upper limit threshold. And determining a corresponding target fine tuning parameter according to the anesthesia depth influence degree parameter, and adjusting the reference first lower limit threshold according to the target fine tuning parameter to obtain a target first lower limit threshold. The smaller the target DOA parameter is, the higher the corresponding anesthetic depth degree is, the further adjustment is needed to be performed on the reference first lower limit threshold value to avoid the situation that the target object is over anesthetized and endangers the safety of the target object, so as to improve the safety of the anesthetic process, and the larger the target DOA parameter is, the lower the corresponding anesthetic depth degree is, and the situation has no safety risk for the target object, so that the reference first upper limit value does not need to be further adjusted. Finally, determining a target DOA threshold range according to the target first lower threshold and the reference first upper threshold, wherein the target DOA threshold range is a DOA threshold range corresponding to the optimal anesthetic effect, and the target DOA threshold range is generally 40-60.

In one possible embodiment, when the target DOA parameter is greater than the upper threshold of the target DOA threshold range, determining a second difference between the target DOA parameter and the upper threshold, determining and triggering a corresponding alarm event according to the second difference, determining an anesthetic drug supplementing amount corresponding to the second difference according to a preset mapping relation between the second difference and the dosage of the target anesthetic drug, generating a second prompting message according to the anesthetic drug supplementing amount, and finally displaying the second prompting message through a visual window, for example, the target DOA parameter is 71, the upper threshold of the target DOA threshold range is 60, the second difference is 11, and triggering a middle-level alarm event. According to a preset mapping relation, assuming that the anesthetic supplement amount corresponding to the second difference value of 5 is 3mg, the generated second prompting information is 'the target object still is 3mg of anesthetic worse', and the second prompting information is used for prompting a guardian to inject 3mg of anesthetic to the target object so as to enable the guardian to reach a proper anesthetic depth.
