What is the role of anesthesia machine?
Speaking of anesthesia machine, in fact, this is a product that can play a general anesthesia effect. The anesthetic can be delivered into the patient's alveoli through a mechanical circuit, and then the partial pressure of the anesthetic gas will be formed. The system directly inhibits, and finally takes effect.
The types of inhalation anesthesia machines are mainly divided into air anesthesia machines, direct-flow anesthesia machines, and closed-circulation anesthesia machines. Most anesthesia machines can provide continuous circulation of oxygen and anesthesia gas, which is called circulatory system.
If it is manual ventilation, the operator must be required to continuously manually squeeze the airbag to make the patient breathe. During a long operation, the operator is not only very tired, but also affects other work. Therefore, automatic ventilator is often used to mechanically allow the patient to breathe.
When using the ventilator, it can force the mixed anesthetic gas into the patient's circuit and breathing system, and accept the breath and fresh gas from the patient. The anesthesiologist can adjust parameters such as tidal volume, respiratory rate, inspiratory-expiratory ratio, and minute ventilation according to the patient's condition. Adjust the ventilation method to meet the various needs of the patient.
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.
