Abstract

The invention relates to an automatic fresh gas control system. An anesthesia system is disclosed herein. The anesthesia system includes a pneumatic circuit comprising an inspiratory limb, an expiratory limb, and a sensor. The anesthesia system also includes an anesthesia machine comprising a controller. The controller is operatively connected to the sensor, and is configured to identify a respiratory phase of the patient based on feedback from the sensor. The controller is further configured to regulate the flow rate of a fresh gas in response to the identified respiratory phase.

Description

technical field [0001] The present disclosure generally relates to a system configured to automatically adjust fresh gas flow during artificial ventilation. Background technique [0002] In general, medical ventilator systems are used to provide respiratory support to patients undergoing anesthesia and respiratory therapy whenever the patient's ability to breathe is impaired. The main function of a medical ventilator system is to maintain the proper pressure and flow of gas inhaled and exhaled by the patient. Medical ventilator systems often include artificial systems that include a collapsible reservoir configured to allow a clinician to deliver artificial breaths to a patient. [0003] The artificial system is implemented to ventilate the patient by repeatedly compressing and releasing the compressible reservoir. Inspiratory gas is diverted to the patient when the collapsible reservoir is compressed. When the collapsible reservoir is subsequently released, the patient p...
