Abstract

A method for maintaining ventilation during an oxygen flush in an anaesthetic breathing apparatus (2) is disclosed. The breathing apparatus (2) comprises a breathing circuit (3), a fresh gas section (5), and a ventilator section (7). The fresh gas section (5) comprises an oxygen supply (12), and the ventilator section (7) comprises an expiratory pressure control valve (21). The method (100) comprises steps of: starting a continuous flow of oxygen from the oxygen supply (12) into the breathing circuit (3) interrupting an ongoing ventilation in order to activate the oxygen flush; maintaining thecontinuous flow of oxygen;, and cycling the expiratory pressure control valve (21) between an upper pressure level setting to provide an inspiratory phase of a breathing cycle and a lower pressure level setting to provide an expiratory phase of the breathing cycle.

Description

technical field [0001] The present disclosure relates to methods for maintaining ventilation during an oxygen flush in an anesthesia breathing apparatus. The present disclosure also relates to a computer program for performing a method for maintaining ventilation during an oxygen flush in an anesthesia breathing apparatus, and a computer program product for executing a method for maintaining ventilation during an oxygen flush in an anesthesia breathing apparatus. The present disclosure also relates to anesthesia breathing apparatus. Background technique [0002] Anesthesia breathing equipment can be used in the operating room. The anesthesia breathing apparatus includes various pressure sensors and regulators, flow control means, gas mixing means and at least one vaporizer for vaporizing a volatile liquid anesthetic agent, referred to simply as “AA”, and the anesthesia breathing apparatus Configured to deliver gas to a patient. The gas supply to the patient consists of fr...
