Abstract: The present invention provides an anesthesia ventilator device that dynamically monitors and regulates the partial pressure of carbon dioxide. The device includes a ventilator main body with inputs connected to an oxygen source, an air source, an anesthetic gas source, and a carbon dioxide source. The output of the ventilator main body is connected to a mask. This invention can solve the technical problem of respiratory alkalosis caused by excessive ventilation in conventional anesthesia ventilator devices, which leads to excessive elimination of carbon dioxide by the patient and a decrease in the partial pressure of carbon dioxide in the body.

Abstract: A method and a ventilator for treating alcohol intoxication based on gas mixing ratio gas supply. The method includes: step (1): mixing oxygen and carbon dioxide gas to generate a target mixed gas, and mixing the target gas based on a preset breathing device so that the gas is delivered to the subject; step (2): monitoring the alcohol concentration in the subject in real time, and at the same time, monitor the partial pressure of carbon dioxide and the respiratory rate in the subject; step (3): stabilizing the partial pressure of carbon dioxide and the respiratory rate in the subject on the basis of the test, when the alcohol concentration in the subject's body meets the safe range, the control preset breathing device stops working. Use different proportions of carbon dioxide CO2 and oxygen O2 to mix the air supply.

Abstract: A method and a system for addressing hyperventilation based on a ventilator device execute steps of: obtaining a carbon dioxide partial pressure of a subject, and determining whether the subject has respiratory alkalosis based on the carbon dioxide partial pressure; obtaining vital sign data of the subject when the respiratory alkalosis occurs and determining a degree of the respiratory alkalosis based on the vital sign data; and adjusting a mixing ratio of oxygen and carbon dioxide based on the degree of the respiratory alkalosis, then re-supplying the subject, and monitoring a respiratory status in real time. The system can quickly and accurately determine whether a subject has respiratory alkalosis by monitoring the carbon dioxide partial pressure, and can effectively alleviate respiratory alkalosis by adjusting mixing ratio of oxygen and carbon dioxide, thus improving the efficiency and safety of resolving respiratory alkalosis caused by hyperventilation.
