3.2

Infusion stopped, insufficient or absent due to a catheter obstruction

Check whether a catheter obstruction is causing the infusion to stop, be insufficient or absent by:



In the case where the drip chamber is used upright (case 2.3 1-a described above): the lack

of drip flow in the drip chamber.



In the case where the drip chamber is not used upright (case 2.3 1-b described above) and

the case where the line does not have a drip chamber: opening of the 3-way stopcock

positioned at the start of the infusion line extension if these elements have been installed.

With the device positioned at the same level as the patient or slightly below the level of

the latter, the net flow of the solute at the 3-way stopcock without blood reflux into the

infusion line signals the absence of permeability at the infusion site.



The catheter is obstructed or bent or has been moved from its initial position

– Reinsert another catheter.

4. END OF INFUSION

The end of the infusion can be checked by observing the inverted pyramid drawn on the

front surface of the mobile plate of the equipment and is reached when the final peak is

visible.

The absence of any flow of the infusion solute if the external port of the 3-way stopcock

is open.

The appearance of blood reflux in the tubing (with the device being located below the

plane on which the patient is lying).

To keep the venous port free (at the end of the infusion), a new infusion bag must be inserted.
