A RESPIRATORY ASSISTANCE DEVICE AND A METHOD OF CONTROLLING SAID DEVICE

摘要

A method of controlling a flow rate of gases supplied to a patient by a respiratory assistance device includes controlling the supply gases flow rate so as to deliver gases to the patient according to a predetermined gases pressure/flow rate profile for at least a portion of the breathing cycle. A profile may be achieved that provides the patient with a particular benefit or therapy.

主权项

1. A method of controlling a flow rate of respiratory gases supplied to a patient by a respiratory assistance device arranged to be in fluid communication with an inspiratory conduit and a patient interface to deliver gases to the patient, and comprising or arranged to be in fluid communication with a respiratory gases source, the method comprising:
controlling the flow rate of respiratory gases supplied to the patient according to a predetermined gases pressure/flow rate profile in a mode defined for at least a portion of a breathing cycle of the patient, wherein the predetermined gases pressure/flow rate profile is configured to alter the flow rate at the end of expiration and/or the beginning of inspiration to increase the clearance of anatomical dead space in the patient.
