Abstract
This disclosure relates generally to a method and an apparatus for delivering a gas to a subject in need thereof, for instance, for the treatment of an unhealthy condition, such as sleep apnea. The method may include sensing the onset of a subject'"'"'s inhalation and delivering a gas, such as a pulse of gas, in response to the subject'"'"'s inhalation. For instance, the method may include providing the subject with a gas delivery device configured for delivering a quantity of gas to the subject, such as in response to the subject'"'"'s need, and instructing the subject to use the device. The device may include a mechanism for generating and delivering the quantity of gas to the subject, as well as a sensor for sensing the subject'"'"'s need for the gas. A controller for controlling the delivery of the gas to the subject in response to the subject'"'"'s sensed need for the gas may also be included. The device may further include a cannula to facilitate delivery of the gas to the subject.

20. A method for treating an unhealthy sleep condition in a subject expected to be suffering there from, comprising:
-
examining the subject'"'"'s sleeping pattern so as to determine the cycle as to when the subject inhales and when the subject exhales while sleeping; providing the subject with a device configured for both delivering a quantity of gas to the subject in response to the onset of an inhalation event and for delivering the gas in accordance with the determined sleeping pattern; and instructing the subject to use the device while sleeping. - View Dependent Claims (21)

22. A device for delivering a quantity of gas to a subject in direct response to the subject'"'"'s need, the device comprising:
-
a gas generator, for generating a quantity of gas and for delivering the same to the subject; a sensor for sensing the subjects need for the gas, and a controller for controlling the delivery of the gas to the subject in response to the subject'"'"'s sensed need for the gas.

23. A low flow resistance cannula system for coupling to a gas delivery device, comprising:
-
a user interface having a set of nostril prongs; transfer tubing; and a gas delivery device interface configured for coupling the user interface to the gas delivery device, wherein the low flow resistance cannula system comprises a pressure drop that is between about 0.1 and about 4 psid when the gas delivery device is delivering a gas that is flowing through the cannula system at 40 liters per minute (lpm). - View Dependent Claims (24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43)
