4.4 Air removal from veins and artery
Attach a blood pressure cuff to the upper arm and inflate to max. 80 mm Hg
(fig. 10), or apply a tourniquet.
Insert a needle of max. 1.0 mm O.D. - mounted on a syringe without piston approximately
1 cm from the end into the first branch of the vein on the back of the hand (fig. 11).
The tube ends being sealed with silicone rubber and a metal ball, no fluid can escape
when the needle is inserted at the very end of the tubes.
When fluid starts flowing into the syringe without air bubbles, pull out the needle
and empty the syringe. Insert the needle into the next vein until the air is removed
from all five vein ends and one artery end.
Correct air removal will be indicated by a colour change on the indicator for the
relevant vein/artery (fig. 12). Check cuff pressure during air removal and adjust if
required, or, when using a tourniquet, tighten as necessary.
Release the pressure from the cuff and remove. If a tourniquet is used, loosen and
remove.
The arm is now ready for training.
Remove the filling tube from the tube connector to check the normal level of the
reservoir fluid (fig. 13). As described under Section 4.3 the system can be refilled with
coloured fluid or destilled water as required.
