Abstract
A nitric oxide delivery system that is useable with any of a variety of gas delivery systems that provide breathing gas to a patient. The system detects the flow of gas delivered from the gas delivery system at various times and calculates the flow of a stream of nitric oxide in a diluent gas from a gas control valve. The flow of gas from the gas delivery system and the flow established from the flow control valve create a mixture having the desired concentration of nitric oxide for the patient. The system does not have to interrogate the particular gas delivery system being used but is an independent system that can be used with various flows, flow profiles and the like from gas delivery systems.
