Claim 4:
5. The breathing assistance apparatus as claimed in claim 1, wherein the breathing assistance apparatus comprises a control system comprising:
a processor operatively configured with the first source, the second source, the first buffer, the second buffer, the mixing chamber, the delivery tank, the first pressure regulator, the second pressure regulator, the third pressure regulator, the one or more first valves, the one or more second valves, the one or more third valves, the one or more fourth valves, the one or more fifth valves, the one or more sixth valves, the one or more first sensing devices, and the one or more second sensing devices, and the processor is configured to execute a set of instructions stored in a memory, upon execution of which, the processor is configured to receive:
a set of first signals, from the first pressure sensing device, pertaining to a first flow pressure value of the first fluid in the first buffer;
a set of second signals, from the second pressure sensing device, pertaining to a second flow pressure value of the second fluid in the second buffer;
a set of third signals, from the third pressure sensing device, pertaining to a third flow pressure value of the third fluid in the mixing chamber;
a set of fourth signals, from the fourth pressure sensing device, pertaining to a fourth flow pressure value of the third fluid in the delivery tank;
a set of fifth signals, from the one or more first sensing devices, comprising a first differential pressure sensing device, pertaining to a first differential pressure value of the third fluid from the delivery tank;
a set of sixth signals, from the one or more second sensing devices, comprising a second differential pressure sensing device, pertaining to a second differential pressure value of the air exhaled by the user; and transmit:
a set of first actuation signals, to the one or more first valves and the first pressure regulator, if the first flow pressure value is any of less than or greater than a pre-defined first threshold value;
a set of second actuation signals, to the one or more second valves and the second pressure regulator, if the second flow pressure value is any of less than or greater than a pre-defined second threshold value;
a set of third actuation signals, to the one or more third valves, if the third flow pressure value is any of less than or greater than a pre-defined third threshold value;
a set of fourth actuation signals, to the one or more fourth valves, if the fourth flow pressure value is any of less than or greater than a pre-defined fourth threshold value;
a set of fifth actuation signals, to the one or more fifth valves, if the first differential pressure value is any of less than or greater than a pre-defined fifth threshold value; and
a set of sixth actuation signals, to the one or more sixth valves, if the second differential pressure value is any of less than or greater than a pre-defined sixth threshold value, wherein the set of first, second, third, fourth, fifth, and sixth actuating signals facilitates controlled breathing assistance to the user.
