Problems solved by technology

At present, most anesthetic gas monitors in the industry have a single function and cannot fully meet the monitoring requirements in clinical scenarios where two anesthetic gases are used for anesthesia and intravenous inhalation combined anesthesia
Most anesthetic gas monitors can only monitor the concentration of one anesthetic gas, or although they can identify the presence of a mixed anesthetic gas, they cannot distinguish the primary and secondary according to the actual anesthetic efficacy, or for the MAC value (minimum alveolar concentration, Minimum alveolar The abbreviation of concentration is a parameter that reflects the depth of anesthesia of the patient) The monitor for primary and secondary anesthetic gas switching, its MAC value calculation coefficient is a fixed value, and the calculated MAC value is inaccurate

Embodiment Construction

[0017] The features and advantages of the present application will be described in detail through embodiments with reference to the accompanying drawings.

[0018] According to clinical verification, the MAC value calculation coefficients corresponding to individuals of different ages, genders, and different races may be different. However, in the prior art, a fixed MAC value calculation coefficient is used. The fixed MAC value calculation coefficient is a legally recommended value, based on a certain from a clinical study. However, due to the limitation of sample size, this clinical study cannot be applied to any situation and cannot meet the needs of clinically variable MAC value calculation, so the calculated MAC value is inaccurate and cannot accurately evaluate the depth of anesthesia of patients.

[0019] Purposeful movement of a body part in response to a perioperative noxious stimulus is one of the most useful clinical signs of depth of anesthesia. MAC is defined as t...

Abstract

The invention discloses an anesthesia monitoring method and a monitor. The anesthesia monitoring method comprises the calculation of an MAC value which comprises the following steps: allowing an operator to set the first calculating coefficient of the MAC value according to the clinic status, detecting the concentration of anesthetic, and calculating the MAC value of the anesthetic; the MAC value of the anesthetic is equal to the concentration of the anesthetic divided by the calculating coefficient of the MAC value of the anesthetic; and the calculating coefficient of the MAC value is a function of the first calculating coefficient of the MAC value set by the operator according to the clinic status, or the calculating coefficient of the MAC value is a function of a numerical value selected from a default and the first calculating coefficient of the MAC value set by the operator according to the clinic status. The invention adopts the calculating coefficient of the MAC value manually set to more accurately respond anaesthesia depth, which is favorable for monitoring during anesthesia.

Description

【Technical field】 [0001] The invention relates to an anesthesia monitoring method and an anesthesia monitoring instrument. 【Background technique】 [0002] In the medical field, anesthesia for patients is mainly divided into three types: gas inhalation anesthesia, intravenous anesthesia and intravenous inhalation compound anesthesia. During anesthesia, clinical workers need to fully understand the concentration, efficacy, metabolism of anesthetic gases and the efficacy of intravenous anesthetics in order to enhance the safety of anesthesia. How to effectively assess the depth of anesthesia in patients and facilitate the monitoring of anesthetized patients is an urgent clinical problem that needs to be solved. At present, most of the anesthetic gas monitors in the industry have a single function and cannot fully meet the monitoring requirements in clinical scenarios where two anesthetic gases are used for anesthesia and intravenous inhalation anesthesia. Most anesthetic gas ...
