A device, system, and method for isolating a ventilator from one or more patients in which the delivery conditions of gas delivered to an isolation device from a ventilator may drive the delivery of breathing-gas delivered to one or more patients, the breathing-gas having the same or different delivery conditions. In one embodiment, an isolation device may have a housing and a movable partition. The movable partition may be joined to the housing, The movable partition may have a patient side on a first side of the partition and an actuating side on a second side of the partition. The isolation device may include an inlet pressure regulator on the actuating side and/or an exhaust pressure regulator on the patient side. These regulators may alter the delivery conditions (including, but not limited to, pressure and volume) of breathing-gas delivered to a patient.

1. A patient respiration isolation device, comprising: a movable partition having an actuating side on a first side of the movable partition, and a patient side on a second side of the movable partition;a housing disposed about the movable partition, the housing having an ventilator orifice adaptable to be in pneumatic communication with a ventilator;an inlet pressure regulator in fluid communication with the actuating side of the movable partition; andan exhaust pressure regulator capable of controlling a positive-end-of-expiration pressure (“PEEP”) in fluid communication with the patient side of the movable partition;further comprising a CO2 scrubber in fluid communication with the patient side of the movable partition. 2. The isolation device of claim 1, wherein the movable partition is a flexible bag. 3. The isolation device of claim 1, wherein the movable partition is comprised of an elastic material. 4. The isolation device of claim 1, wherein the movable partition comprises a bellows and a diaphragm. 5. The isolation device of claim 1, further comprising a position sensor capable of detecting a position of the movable partition. 6. The isolation device of claim 1, wherein the housing includes a fresh gas orifice for providing fresh gas from a fresh gas source, and wherein the fresh gas orifice is in fluid communication with the patient side of the movable partition. 7. The isolation device of claim 1, further comprising an exhaust line extending from the housing, wherein the exhaust line is in fluid communication with the patient side of the movable partition. 8. The isolation device of claim 1, wherein the inlet pressure regulator comprises a flexible tube and a caliper. 9. The isolation device of claim 1, wherein the exhaust pressure regulator comprises a flexible tube and a caliper. 10. The isolation device of claim 1, wherein the exhaust pressure regulator comprises a Starling resistor. 11. The isolation device of claim 1, further comprising a tether having a first end and a second end, wherein the first end is connected to the movable partition and the second end is connected to the housing. 12. The isolation device of claim 1, further comprising a pneumotachometer connected to the ventilator orifice and capable of measuring a gas volume of gas flowing into and/or out of the housing. 13. The isolation device of claim 1, wherein the housing further comprises a patient orifice in fluid communication with the patient side of the movable partition and the patient orifice is adaptable to be in fluid communication with a patient. 14. The isolation device of claim 13, further comprising a pneumotachometer connected to the patient orifice and capable of measuring a gas volume of gas flowing into and/or out of the housing. 15. A method for enhancing the performance of a ventilator comprising the steps of: providing a ventilator;providing an isolation device having a movable partition for separating gas in an actuating side of the isolation device, from gas in a patient side of the isolation device, wherein the isolation device has an inlet on the actuating side connected to the ventilator, wherein the isolation device has an inlet pressure regulator on the actuating side, and wherein the isolation device has an exhaust pressure regulator on the patient side, the exhaust pressure regulator controlling a positive-end-of-expiration pressure (“PEEP”) in fluid communication with the patient side;providing a CO2 scrubber in fluid communication with the patient side of the isolation device;utilizing the ventilator to drive a respiratory cycle in the isolation device; andutilizing the isolation device to provide mechanical ventilation of the lungs of a patient. 16. The method of claim 15, further comprising the steps of: providing a second isolation device having an inlet connected to the ventilator;utilizing the ventilator to drive a respiratory cycle in the second isolation device; andutilizing the second isolation device to provide mechanical ventilation of the lungs of a second patient. 17. The method of claim 16 wherein the second isolation device further comprises: a movable partition for separating gas in an actuating side of the second isolation device, from gas in a patient side of the second isolation device; andwherein the inlet of the second isolation device is on the actuating side of the second isolation device. 18. The method of claim 17 wherein the second isolation device further comprises an inlet pressure regulator on the actuating side. 19. The method of claim 17 wherein the second isolation device further comprises an exhaust pressure regulator on the patient side.
