Abstract
The present disclosure pertains to a system for controlling a leak flow rate during respiratory therapy. The system is configured to determine a leak flow rate necessary for CO2 expulsion for an individual subject and facilitate control of the leak flow rate during therapy such that the system exhausts substantially the entire exhaled volume of gas during an expiration of the subject. The system facilitates control of the leak flow rate during therapy via an adjustable leak valve. Determining the leak flow rate for the subject and facilitating control of the leak rate may minimize noise from air flow in the system, minimize the power draw needed by a pressure generator of the system, reduce a loss of medicine added to the respiratory therapy gas, and/or have other advantages, while still expelling the desired amount of CO2.
