If, after connecting the pressure monitoring set to a patient, it is found that the signals displayed on the patient screen exhibit overshoot

Due to (incipient) occlusion of the patient access port, drawing or returning liquids using a reservoir (NBSS, NBSS
ABSS & ABSS confi gurations) or a blood sampling container can generate too great a vacuum or excess pressure in the
XL
tubing system of the pressure monitoring set. This may cause blood cells to be damaged (haemolysis) and blood test results
could thus be distorted. Moreover, it can lead to the ingress/leakage of liquids, air and/or pathogens. Prior to every blood
sampling, check that the patient access port is patent and continuous.
The surface of the sampling port must be disinfected before and after each use and must be free of any blood residue
(spray and/or wipe disinfection) to prevent the ingress of pathogens and blood clots into the pressure monitoring set (see
section 14, page 60 – Disinfection instructions). Prior to use, also ensure that the used disinfectant has completely
evaporated. Disinfectant that has not evaporated can damage the components and lead to distortion of the blood analyses
due to haemolysis of the blood samples.
Too rapid drawing or returning of liquids using a reservoir (NBSS, NBSS
sampling container can generate too great a vacuum or excess pressure in the tubing system. This may cause blood cells
to be damaged (haemolysis) and blood test results could thus be distorted. Moreover, it can lead to the ingress/leakage of
liquids, air and/or pathogens. To carry out a complication-free volume shift, the reservoirs and blood sampling containers
must always be operated carefully and without any noticeable resistance.
Clotted blood (coagulum) inside the tubing system can cause clogging of the patient access port and a loss of function
of the pressure monitoring set. Moreover, infi ltration of coagulum into the patient's circulatory system can cause vascular
occlusion. To prevent coagulum from forming inside the pressure monitoring set, all the components involved in blood
sampling should be checked for blood residue after the blood sampling process by means of a visual inspection, and all
residue must be removed using the rapid fl ushing function. For pressure monitoring sets with an NBSS, NBSS
or ABSS , remove the reservoir from its designated fi xture in order to better inspect the bottom of the plunger stopper for
XL
blood residue. If residue is detected, fl ush the component with pure saline solution while gently opening and closing the
control knob.
Do not sample blood via the S.E.R.O. damping stopcock because this can lead to coagulum forming inside the compo-
nent. Clotted blood (coagulum) can lead to the patient access port becoming clogged and to a functional impairment
or loss of function of the component and/or the entire pressure monitoring set. Moreover, infi ltration of coagulum into the
patient's circulatory system can cause vascular occlusion.
No valid pressure transmission is possible throughout the entire blood sampling process due to the various manipulations of
the components between the patient connection and pressure transducer with accompanying movement artefacts.
