A ventilation system can include a flow generator that can be connected to a gas supply tube. The gas supply tube can be in fluid communication with a ventilation interface. At least a portion of the gas supply tube can have a divider within the channel of the tube forming a nasal passageway and an oral passageway. A nasal breathing chamber and an oral breathing chamber can be defined in the ventilation interface. The nasal breathing chamber can be in fluid communication with the nasal passageway. The oral breathing chamber can be in fluid communication with the oral passageway. ## Claims ### Claim 1 A respiratory mask comprising: a respiratory interface having a gas entry port and having a plurality of gas receiving chambers; a gas supply tube, wherein the gas supply tube is in fluid communication with the respiratory interface wherein the plurality of gas receiving chambers includes a first gas receiving chamber and a second gas receiving chamber and the respiratory mask is structured to allow gas to flow from the gas supply tube into the first gas receiving chamber and the second gas receiving chamber at the same time. ### Claim 2 (depends on 1) The respiratory mask of claim 1, wherein the plurality of gas receiving chambers include a nasal breathing chamber and an oral breathing chamber. ### Claim 3 (depends on 1) The ventilation mask of claim 1, wherein the plurality of gas receiving chambers is configured to receive gas through a single gas entry port during use. ### Claim 4 (depends on 1) The respiratory mask of claim 1, wherein the plurality of gas receiving chambers are not in fluid communication to each other. ### Claim 5 (depends on 1) The respiratory mask of claim 1, wherein at least one of the plurality of gas receiving chambers includes a valve, which adjusts the fluid flow from the gas supply tube to at least one of the plurality of gas receiving chambers. ### Claim 6 (depends on 2) The respiratory mask of claim 2, wherein the respiratory interface includes a dividing wall that provides a substantially airtight seal between the nasal breathing chamber and the oral breathing chamber. ### Claim 7 (depends on 1) The respiratory mask of claim 1, wherein the respiratory interface includes nasal prongs that are adapted to enter at least one of the nostrils of a user. ### Claim 8 (depends on 6) The respiratory mask of claim 6, wherein the gas entry port abuts the dividing wall. ### Claim 9 A respiratory mask comprising: a respiratory interface having a gas entry port and having a first gas receiving chamber and a second gas receiving chamber; a gas supply tube, wherein the gas supply tube is in fluid communication with the respiratory interface wherein the respiratory interface has a dividing wall between the first gas receiving chamber and the second gas receiving chamber that is configured to separate the gas received through the gas entry port during use. ### Claim 10 (depends on 9) The respiratory mask of claim 9, wherein at least one of the gas receiving chambers includes a valve, which adjusts the fluid flow entering the gas receiving chamber. ### Claim 11 (depends on 9) The respiratory mask of claim 9, wherein the dividing wall provides a substantially airtight seal between the first gas receiving chamber and the second gas receiving chamber. ### Claim 12 (depends on 9) The respiratory mask of claim 9, wherein the dividing wall abuts the first gas receiving chamber and the second gas receiving chamber. ### Claim 13 (depends on 9) The respiratory mask of claim 9, wherein the respiratory mask is structured to allow the flow rate into at least one of the gas receiving chambers to be adjusted. ### Claim 14 (depends on 9) The respiratory mask of claim 9, wherein the respiratory mask includes nasal prongs that are adapted to enter at least one of the nostrils of a user. ### Claim 15 (depends on 9) The respiratory mask of claim 9, wherein the gas entry port abuts the dividing wall. ### Claim 16 A respiratory mask comprising: a respiratory interface having a gas entry port and having a plurality of gas receiving chambers; a gas supply tube, wherein the gas supply tube is in fluid communication with the respiratory interface wherein the respiratory interface has a dividing wall between the plurality of gas receiving chambers, wherein the dividing wall abuts the gas entry port. ### Claim 17 (depends on 16) The respiratory mask of claim 16, wherein at least one of the gas receiving chambers includes a valve, which adjusts the fluid flow entering the gas receiving chamber. ### Claim 18 (depends on 16) The respiratory mask of claim 16, wherein the respiratory mask is structured to allow the flow rate into at least one of the gas receiving chambers to be adjusted. ### Claim 19 A respiratory mask comprising: a respiratory interface having at least one gas entry port and having a plurality of gas receiving chambers; at least one gas supply tube, wherein the gas supply tube is in fluid communication with the respiratory interface wherein the respiratory mask is structured to allow the flow rate into at least one of the plurality of gas receiving chambers to be adjusted. ### Claim 20 (depends on 19) The respiratory mask of claim 19, wherein at least one of the plurality of gas receiving chambers includes a valve.
