The accessory of claim 2, wherein the device comprises a nebulizer that delivers the aerosol particles at a prescribed flow rate. 15. The accessory of claim 2, further including a third valve that is associated with one of the fifth port and third port, the third valve moving between an open position when the patient inhales causing the second leg conduit and second compartment to be in fluid communication and a closed position when the patient exhales, thereby fluidly closing off the second compartment from the second leg conduit. 16. The accessory of claim 15, wherein the third valve is a one-way valve and wherein, as the patient inhales, the supplemental gas stored in the second compartment is free to flow through the second leg conduit into the main conduit body to the patient to supplement the aerosol particles flowing through the first leg conduit. 17. The accessory of claim 15, wherein the third valve is formed in the fifth port at a location that is above an inlet of the supplemental gas into the fifth port such that the inlet is between the fifth valve and the second compartment. 18. An aerosol inhalation system comprising: at least one device for producing aerosol particles for delivering medication to a patient through a piece of equipment in communication with a respiratory system of the patient; an accessory for interfacing between the at least one device and the piece of equipment, the accessory comprising: a main conduit body having a first end connected to the piece of equipment and a second end, wherein aerosol particles produced by the device flow into the first end and into the main conduit body toward the second leg, the main conduit body including a patient port that is for placement close to a mouth of a patient for delivering the medication thereto; a first leg conduit in fluid communication with the main conduit body and including a distal end; a second leg conduit in fluid communication with the main conduit body and including a distal end, the second leg conduit being spaced apart from the first leg conduit; a holding chamber having a first compartment and a second compartment separated from the first compartment, with the first compartment being sealingly and fluidly coupled to the first leg and the second compartment being sealingly and fluidly coupled to the second leg; and an arrangement of valves including a first valve in the form on an inhalation valve that is disposed along the main conduit body between the first and second legs and between the second leg and the patient port, wherein when the first valve opens, a flow path is created between the device that produces the aerosol particles and the patient port and between the second leg and patient to permit the medication to flow freely through the main conduit body to the patient, wherein when the first valve is closed, medication is prevented from flowing from the device to the patient port and from the second leg to the patient port, thereby resulting in the medication being stored in the second compartment which is open to the main conduit body, wherein a second valve is provided for venting the main conduit body when the patient exhales; wherein the holding chamber is defined by a reservoir bag with the first and second compartments therein and separated from one another by a bi-furcating wall, the reservoir bag being formed of a expandable/collapsible material. 19.
