Using The Ambu I.v. Trainer - Ambu I.V. Trainer Bedienungsanleitung

5. Using the Ambu l.V. Trainer
The Ambu I.V. Trainer is suitable for training in the following procedures:
• Preparation and handling of puncturing equipment.
• Venous stasis using blood pressure cuff or tourniquet.
• Selection of site for puncture.
• Disinfection procedure.
• Puncturing and insertion methods.
• Verification of correct positioning.
• Preparation and start of injection and infusion.
• Fixation of catheters and tubes.
• Puncturing of radial artery.
• Arterial blood sampling.
• Handling of equipment for venous blood sampling.
To create a "blood pressure" in the arm, attach a blood pressure cuff or a tourniquet
in the usual way for venepuncture of patients.
Inflate the cuff to approx. 80 mm Hg, or tighten the tourniquet before puncturing
the vein.
Release the air from the cuff or loosen the tourniquet before commencing infusion.
Do not inflate the cuff above 80 mm Hg, since higher pressure may cause
"the blood" to spurt violently from the needle during puncture.
Do not use needles larger than 1.0 mm O.D. (gauge 20) so as not to wear out
veins and skin too quickly.
If the needle or cannula is correctly positioned, one of the four transparent indicator
tubes on the shoulder joint will change colour during injection or infusion of
In order to make the indicator tube turn red again, draw back the transparent
liquid until the cannula turns red.
5.1 Pulse-taking
The instructor can simulate arterial pulse by pressing the bellows.
