Meilun: Is the breathing anesthesia machine safe to use? Why is there an alarm monitoring system?

Anesthesia machine is a kind of medical equipment that can deliver a variety of gases and volatile anesthetics, control and assist the patient's breathing, and at the same time adjust the patient's consciousness and pain level during the operation. In order to reduce the impact of anesthesia accidents on the safety of patients caused by device failure, the monitoring and alarm system of the anesthesia machine is indispensable. Let me introduce the function and principle of the monitoring and alarm system of the anesthesia machine.

Effective anesthesia depth monitoring can prevent excessive anesthesia, prevent anesthesia accidents, accurately predict the patient's recovery time, reduce the amount of anesthetics, and improve the safety of anesthesia. Configure the depth of anesthesia monitoring function on the anesthesia machine, and it has begun clinical application.

The anesthesia machine has a set of monitoring-related devices according to different configurations, such as monitoring the airway, physiology, anesthetic gas concentration, and monitoring that can indirectly reflect the patient's anesthesia depth and muscle relaxation. The monitoring system of most anesthesia machines is only equipped with a basic monitoring device as a platform for the system. The monitoring content includes: airway pressure, inhaled tidal volume, minute ventilation, respiratory rate and related alarm systems.

The anesthesia breathing control board processes the airway pressure and tidal volume collected by the pressure sensor and flow sensor according to the breathing mode and parameters set by the panel operation, and then controls the inhalation time, expiration time, respiratory frequency, tidal volume, etc. . At the same time, the monitored respiratory parameter values are displayed on the panel.

The anesthesia breathing control board also performs an audible and visual alarm when the monitored breathing parameter value exceeds the alarm parameter setting value according to the alarm parameters set by the panel operation.

The breathing gas monitor control panel processes the breathing gas collected by the gas sampling module and displays the monitoring parameter values on the panel. The breathing gas monitor control board also performs an audible and visual alarm when the monitored gas parameter value exceeds the alarm parameter setting value according to the alarm parameters set by the panel operation.

In addition, the anesthesia workstation needs to be equipped with an anesthesia information management system, which can receive, analyze, and store information related to the clinical and administrative management of anesthesia, automatically collect information from the monitor and automatically generate an anesthesia record sheet.

With the continuous research and improvement of anesthesia machines for decades, modern anesthesia machines are equipped with electronic, computer control and monitoring instruments, multi-functional modern anesthesia machines and high-level The combination of clinicians will greatly improve the safety of anesthesia and mechanical ventilation treatment.
