7 To the metallic nozzle attach the clear oxygen tubing from the oxygen source.
(3) The breathing system (See Fig. 3)
The following parts of the breathing system are identified:
1. The valve unit. This consists of two separate clear cylindrical valves known as the inspiratory
(A) and expiratory (B) valves, connected by a 20cm length of clear narrow tubing (C). The
inspiratory valve is long, narrow and has a side port. The expiratory valve is short, wide and has
a fixing bracket.
2. Self-inflating bag (D) (a smaller size is available for children)
3. A dual limb of 22mm Silicon tubing (E) ending in a standard 'Y' piece
4. A 1 litre reservoir bag to act as test lung.
5. A length of standard respiratory tubing for scavenging of expired gases.

1. Attach the narrow inspiratory valve (A) to the exit port of the vaporiser. Rotate the valve so that the
side port points downwards and forwards at an angle of approx. 45 degrees.
2. Attach the self inflating bag (D) to the side port of the inspiratory valve so that it lies in front of the
case pointing downwards (this can also be connected by the additional supplied 22mm silicone tube).
3. Take the expiratory valve (B) and insert the on to the case. Tighten the metallic screw located below
the expiratory valve to secure it in position.
4. Attach one side of the dual limb respiratory tubing to the inspiratory valve and the other to the
expiratory valve.
5. Attach scavenging tube to expiratory valve 30mm outlet.
To test the assembly: Attach the test lung (1 litre green reservoir bag) to the patient end 'Y' piece of the
respiratory tubing and confirm the integrity of the system using the self inflating bag.
