Abstract
Provided herein are systems and methods for delivery of therapeutic gas to patients, in need thereof, by receiving breathing gas from a high frequency ventilator using at least enhanced therapeutic gas (e.g., nitric oxide, NO, etc.) flow measurement. At least some of these enhanced therapeutic gas flow measurements can be used to address some surprising phenomenon that may, at times, occur when wild stream blending therapeutic gas into breathing gas a patient receives from a breathing circuit affiliated with a high frequency ventilator. Utilizing at least some of these enhanced therapeutic gas flow measurements the dose of therapeutic gas wild stream blended into breathing gas that the patient receives can at least be more accurate and/or under delivery of therapeutic gas into the breathing gas can be avoided and/or reduced.
