Possible causes
Insuffi cient rapid fl ushing
Loose Luer interfaces
Flow channel not patent
Incorrect position or incipient
occlusion of the patient access port
Pressure transducer incorrectly
connected to the electrical
accessories
Electrical accessories damaged or
defective
Incorrect assembly and/or zero
calibration of the pressure monitoring
set
Flow channel not patent
Incorrect position or incipient
occlusion of the patient access port
Air bubbles in the tubing system
Incorrect assembly and/or zero
calibration of the pressure monitoring
set
Use of unapproved sterile accessories
to supplement, extend or change the
confi guration and/or components of
the pressure monitoring set
Insuffi cient damping of the pressure
signal
Insuffi cient fl ushing
Loose Luer interfaces
Flow channel not patent
Incorrect position or incipient
occlusion of the patient access port
Control knob turned too quickly
Flow channel not patent
Incorrect position or incipient
occlusion of the patient access port
Control knob turned too quickly
Use of unsuitable blood sampling
containers
Use of cannulas/needles
Use of unapproved disinfectant
Inadequate evaporation of the
disinfectant
Fault rectifi cation / prevention
Check the pressurisation of the saline bag or the fl ow rate of the
syringe pump and correct if required
Identify twisted or kinked tubes and correct if required
Check the stopcock positions and correct if required
Check the patency of the fi lling and irrigation system and correct if
required
Check the Luer interfaces and tighten by hand if required
Identify twisted or kinked tubes and correct if required
Check the stopcock positions and correct if required
Check the patency of the patient access port and replace if required
Check the pressurisation of the saline bag or the fl ow rate of the
syringe pump and correct if required
Carefully remove all blood residue from the pressure monitoring set
after blood sampling
Check the connection between the pressure transducer and electrical
accessories and correct if required
Always handle, clean and store electrical accessories with the utmost
care
Check the positioning height of the pressure transducer and correct if
required and carry out another zero calibration
Identify twisted or kinked tubes and correct if required
Check the stopcock positions and correct if required
Check the patency of the patient access port and replace if required
Check the pressurisation of the saline bag or the fl ow rate of the
syringe pump and correct if required
Carefully remove all blood residue from the pressure monitoring set
after blood sampling
Inspect the pressure monitoring set and, if required, remove air
bubbles by means of rapid fl ushing or by gently tapping the affected
components
Check the positioning height of the pressure transducer and correct if
required and carry out another zero calibration
Only use approved CODAN pvb Critical Care sterile accessories and
contact the manufacturer or distributor for more information if required
Use an S.E.R.O. damping stopcock
Check the pressurisation of the saline bag or the fl ow rate of the
syringe pump and correct if required
Check the stopcock positions and correct if required
Check the patency of the fi lling system and correct if required
Check the Luer interfaces and tighten by hand if required
Identify twisted or kinked tubes and correct if required
Check the stopcock positions and correct if required
Check the patency of the patient access port and replace if required
Check the pressurisation of the saline bag or the fl ow rate of the
syringe pump and correct if required
Carefully remove all blood residue from the pressure monitoring set
after blood sampling
Always operate the control knob of the reservoir carefully and without
any noticeable resistance
Before operating the reservoir, turn the OFF tap of the 3-way zeroing
stopcock in the direction of the patient (NBSS & ABSS)
Identify twisted or kinked tubes and correct if required
Check the stopcock positions and correct if required
Check the patency of the patient access port and replace if required
Check the pressurisation of the saline bag or the fl ow rate of the
syringe pump and correct if required
Carefully remove all blood residue from the pressure monitoring set
after blood sampling
Always operate the control knob of the reservoir carefully and without
any noticeable resistance
Use of blood sampling containers and adapters manufactured in
accordance with the applicable standards and which are CE marked
Use of blood sampling containers with Luer interfaces
Use of iodine-containing disinfectants or standard 1-propanol,
2-propanol or ethanol-based disinfectants
Before using the relevant components, allow the applied disinfectant
to completely evaporate
