Method and system of sensing airflow and delivering therapeutic gas to a patient
Sensing airflow and delivering therapeutic gas to a patient. At least some of the example embodiments are methods including: titrating a patient with therapeutic gas during a period of time when a flow state of breathing orifices is in a first state, the titrating results in a prescription titration volume; and then delivering the prescription titration volume of therapeutic gas to the patient when the flow state of the breathing orifices is in a second state different than the first state, the delivering only to the breathing orifices open to flow.
1. A method comprising:
outputting, by a conserver system, a control signal arranged to cause therapeutic gas to be delivered by, during an inhalation:
receiving individually sensed airflow of a first breathing orifice and a second breathing orifice of a patient;
determining initially that the first breathing orifice is open to flow and the second breathing orifice is closed to flow, the determining based on the individually sensing;
outputting a control signal arranged to cause delivery of the therapeutic gas to the first breathing orifice to begin; and then
determining that during the inhalation the second breathing orifice opens to flow; and
outputting a control signal arranged to cause delivery of the therapeutic gas to begin to the second breathing orifice after beginning delivery of therapeutic gas to the first breathing orifice; and
outputting a control signal arranged to cause delivery of therapeutic gas to cease to both orifices when a total volume delivered is a prescription titration volume.
2. A method comprising:
delivering a prescription titration volume of therapeutic gas to a patient, the delivering only to breathing orifices open to flow, the delivering by, during an inhalation:
individually sensing airflow of a first breathing orifice and a second breathing orifice of the patient;
determining initially that the first breathing orifice is open to flow and the second breathing orifice is closed to flow, the determining based on the individually sensing airflow;
beginning delivery of the therapeutic gas to the first breathing orifice; and then
determining that during the inhalation the second breathing orifice opens to flow; and
beginning delivery of the therapeutic gas to the second breathing orifice after beginning delivery of therapeutic gas to the first breathing orifice; and
ceasing delivery of therapeutic gas to both orifices when a total volume delivered is the prescription titration volume.
