Method and ventilator for treating alcohol intoxication by supplying gases based on gas mixing ratio

A ventilator for treating alcohol intoxication based on gas mixing ratio, comprising:

• a gas transmission module configured to mix oxygen and carbon dioxide to generate a target gas mixture, and transmit the target gas mixture to a subject based on a preset breathing device;
• a monitoring module configured to monitor an alcohol concentration in the subject in real time, and meanwhile, monitor a partial pressure of carbon dioxide and a respiratory rate in the subject;
• a control module configured to control the preset breathing device to stop working when the alcohol concentration in the subject meets a safe range on the basis of the partial pressure of the carbon dioxide and the respiratory rate of the subject are stable;
• wherein in the gas transmission module, mixing the oxygen and the carbon dioxide to generate the target mixed gas, comprising:
• collecting a current alcohol concentration of the subject, and at the same time, determining current body characteristic indexes of the subject;
• inputting the current alcohol content concentration of the subject and the current body characteristic indexes of the subject into an alcohol analysis model for analysis;
• based on analysis results in the alcohol analysis model, determining an oxygen concentration and a carbon dioxide concentration that the subject needs respectively;
• based on the oxygen concentration and the carbon dioxide concentration that the subject needed respectively, determining a mixing ratio of the oxygen and carbon dioxide;
• based on the mixing ratio, mixing the oxygen and the carbon dioxide to generate the target mixed gas;
• wherein in the monitoring module, monitoring the alcohol concentration in the subject's body in real time, and at the same time, monitoring the partial pressure of carbon dioxide and the respiratory rate of the subject, comprising:
• when the target mixed gas is transmitted to the subject based on the preset breathing device, start a first monitoring instruction and a second monitoring instruction;
• monitoring a dynamic alcohol concentration in the subject in real time based on the first monitoring instruction;
• monitoring a partial pressure of carbon dioxide in the subject and the respiratory rate of the subject in real time based on the second monitoring instruction;
• according to a preset time point, dynamic alcohol change concentrations are recorded in one-to-one correspondence with the partial pressure of the carbon dioxide and the respiratory rate in the subject;
• based on recorded results, generating a monitoring dynamic table and displaying in real time.
