• Recent use of anti-platelet drugs
• Inability to maintain stable oncotic pressure
31. When collecting PRP, LivaNova recommends the following precautions be taken to insure that the
PRP product is not contaminated:
• Use sterile techniques when setting up the X
TRA
disposables.
• Thoroughly clean and disinfect the donation site.
• Use sterile techniques whenever handling the PRP product.
32. Make sure to open a blood collection (plasma) bag flow path before closing the waste bag port.
Failure to do so may result in fluid leaking from the centrifuge bowl seal.
33. Any device connected to the RS232 port must comply with the applicable IEC standard for that
device.
34. In the event that a hematocrit value is desired and not obtained with the Hct Sampling System of
the unit, use an alternate means of measuring hematocrit.
35. Prior to collecting any blood, prime the reservoir with approximately 200 ml of the anticoagulant
solution.
36. In the event of anticoagulant deficiency in collection reservoir due to inappropriate ratios, the
savaged blood may clot in the reservoir.
37. Avoid use of Ringer’s when using citrate anticoagulant as the simultaneous use of incompatible IV
fluids may cause clotting in the system.
38. Use only X
TRA
USB memory sticks.
39. Be sure to properly place and hook the machine to the cart in order to avoid the danger of the
machine falling.
40. If the display shows incomprehensible and erroneous messages or messages different from those
indicated in this manual, immediately stop the unit and contact LivaNova Technical Service.
41. In the event of problems with the automatic removal of the lid opening lock: (a) do not attempt
to force open the lid; (b) switching the machine off and on might resolve the problem; (c) if the
problem persists, contact authorized technical service.
42. The Waste bag must not be squeezed while treatment is being done and must have the space to
fill up properly. If the bag is squeezed or cannot fill up properly because it is positioned near an
obstacle (for example, a wall) a reflux toward the bowl or a back pressure might be created
sufficient to cause the liquid to leak from the bowl seal
43. A failed or improper connection of the lines can lead to the risk of gas or liquids entering the
circuit from the environment.
44. Strictly adhere to these disposable installation instructions to guarantee the proper execution of
the treatment. In particular, be careful with the: (a) proper connection of the RBC bag to avoid
leakage of red blood cells, (b) proper connection of the wash bag to guarantee proper washing,
and (c) proper connection of the reservoir to allow access to the blood to be processed.
45. In the event of problems with the automatic unloading of the pump circuit, open the lid of the
centrifuge and manually remove the tubing of the pump circuit from the pump rotor: Rotate the
pump rotor counterclockwise while extracting the tubing of the pump circuit.
46. Always close the centrifuge lid before starting any function of the machine that uses the pump
and/or centrifuge action to avoid the risk of touching any moving parts of the device.
47. The use of phase buttons and, in general, modifications that alter the normal execution of
protocols can create reductions of normal machine performance. It is the responsibility of the
user to evaluate if and when these procedures can be performed.
48. The availability of alarms does not relieve the operator of his or her obligation to carefully monitor
the entire system during operation. Unattended processing can lead to the development of
problems with the operation of the system and/or with the quality of the end product.
