Abstract
A system for delivering warm, humidified oxygen to patients at very low flow rates, the system including a conduit having an inlet connected to a source of humidified oxygen at a first flow rate and an outlet end for delivering humidified oxygen to a patient at a second flow rate that is less than the first flow rate. A first flowpath extends through a sidewall of the conduit for continuously bleeding oxygen from the conduit and a second flowpath extends through the sidewall of the conduit downstream from the first flowpath for continuously bleeding oxygen from the conduit at a rate of from about 0 liters/minute or above. A substantially solid member is movably positionable adjacent the second flowpath for selectively blocking and unblocking portions of the second flowpath for defining a variably dimensionable flow path in order to control over the amount of oxygen flowing through the second flowpath.
