Claim 0:
1. A breathing assistance apparatus for providing a breathing assistance to a user, the breathing assistance apparatus comprising:
a first source;
a first buffer, having a first pressure sensing device, operatively configured with the first source to controllably receive a first fluid from the first source, wherein the first fluid is controllably transferred to the first buffer using any or a combination of a first pressure regulator and one or more first valves;
a second source;
a second buffer, having a second pressure sensing device, operatively configured with the second source to controllably receive a second fluid from the second source, wherein the second fluid is controllably transferred to the second buffer using any or a combination of a second pressure regulator and one or more second valves;
a mixing chamber, having a third pressure sensing device, operatively configured with the first buffer and the second buffer to controllably receive the first fluid and the second fluid through one or more third valves, wherein the mixing chamber is configured to mix the first fluid and the second fluid to form a third fluid;
a delivery tank, having a fourth pressure sensing device, operatively configured with the mixing chamber to controllably receive the third fluid through any or a combination of one or more fourth valves and a third pressure regulator; and
a user feed mask having an inlet operatively configured with the user's face for facilitating breathing assistance to the user, and the inlet is operatively configured with the delivery tank to controllably receive the third fluid, through any or a combination of one or more fifth valves and one or more first sensing devices, and an outlet configured to exhaust an air exhaled by the user, wherein the outlet is configured with any or a combination of one or more sixth valves and one or more second sensing devices.
