Three Phases of Anesthesia

A) First Phase: Animal(s) are placed in the induction chamber where they are initially anesthetized with an exact concentration of anesthetic, typically isoflurane.

B) Second Phase: Anesthetized animal is transferred from the induction chamber onto a surgical bed with a breathing device and mask that supplies a constant flow of anesthetic gas to keep the animal safely anesthetized during procedures.

C) Third Phase: Animal is placed in a clean chamber for recovery.

1 ) Oxygen Source that can be supplied from an in-house line or tank. The oxygen functions as a carrier for the anesthetic gas and serves as a blending agent to control the concentration of anesthetic.

2) Oxygen Regulator controls the pressure of oxygen from its source into the flowmeter that inputs into the vaporizer.

3) Flowmeter 1 controls the flow rate of oxygen into the vaporizer.

4) Vaporizer precisely blends oxygen and the anesthetizing liquid to create an anesthetic gas at the exact
concentration level required.

5) Manifold distributes anesthetic gas to the induction chamber and the breathing devices.

6) Flowmeter 2 controls the flow rate of the anesthetic gas output from the vaporizer manifold to the induction chamber.

7) Induction Chamber facilitates initial anesthetizing of animal before placing on surgical bed for procedure. (Pictured with a chamber warmer to maintain animal body temperature.)

8) Oxygen Flush purges the induction chamber of anesthetic gas to ensure that no anesthetic is released into the room when transferring animals from the chamber to the surgical bed.

9) Breathing Device delivers precisely controlled anesthetic gas to the animal.

10) Nosecone provides a secure fit for the delivery of anesthetic gas from the breather to the animal and minimizes the escape of gas into the room.

11) Surgical Bed acts as a stable surface for procedures and may be water-heated for precise control of body temperature during procedures.

12) Water Heating Pump provides precisely controlled, circulating heated water to the surgical bed and the
induction chamber warmer.

13) Charcoal Filter Canister captures anesthetic gas from all components preventing escape of gas into the room.
