Abstract
The present invention generally relates to systems and method for delivery of therapeutic gas to patients in need thereof using enhanced breathing circuit gas (BCG) flow measurement. At least some of these enhanced BCG flow measurements can be used to address some surprising phenomena that may, at times, occur when wild stream blending therapeutic gas into breathing gas that a patient receives from a breathing circuit affiliated with a ventilator. Utilizing at least some of these enhanced BCG flow measurements the dose of therapeutic gas wild stream blended into breathing gas that the patient receives from a ventilator can at least be more accurate and/or over delivery of therapeutic gas into the breathing gas can be avoided and/or reduced.
