Medela Invia White Foam Mode D'emploi page 9

Defibrillation: Remove the dressing if defibrillation is required in the area of dressing place-
ment. Failure to remove the dressing may inhibit transmission of electrical energy and/or
patient resuscitation.
Magnetic Resonance Imaging (MRI):
– Therapy Unit: Invia NPWT systems are not for use in the Magnetic Resonance (MR) Environ-
ment, so do not take an Invia NPWT device into this environment.
– Dressings: After disconnecting from the Invia NPWT system, dressings can typically remain
on the patient with no risk in a MR environment (all components are electrically nonconduc-
tive and nonmagnetic items).
Hyperbaric Oxygen Therapy (HBOT):
– Therapy Unit: Do not bring Invia NPWT systems into HBOT Chamber.
– Dressings: After disconnecting the Invia NPWT system from the dressing, either (i) replace
the Invia Foam Dressing with another HBOT compatible material during the hyperbaric treat-
ment or (ii) cover the unclamped end of the tubing with moist cotton gauze and completely
cover the Invia Foam Dressing (including tubing) with a moist towel throughout the treatment
in the chamber. For Hyperbaric Oxygen Therapy, the tubing must not be clamped.
Course of therapy: Invia Negative Pressure Wound Therapy Instructions advise 24 hours ther-
apy without interruption. If therapy is discontinued for more than 2 hours, the dressing should
be replaced and therapy restarted by a healthcare professional. If the therapy needs to be
interrupted, the tubing should be clamped and the ends of the tubing protected.
CAUTIONS
The following statements describe conditions that may require special care for the safe
and effective use of the Invia White Foam.
– Patients receiving anticoagulant therapy or platelet aggregation inhibitors, actively
bleeding or have weakened blood vessels or organs.
– Patients suffering from difficult wound hemostasis.
– Patients untreated for malnutrition.
– Noncompliant or combative patients.
– Patients suffering from wounds in close proximity to blood vessels or delicate fascia.
– Patients with infected wound or osteomyelitis.
– Patients with Spinal Cord Injury (sympathetic nervous system stimulation): in the event
a patient experiences autonomic dysreflexia (sudden changes in blood pressure or
heart rate in response to stimulation in response to stimulation of the sympathetic
nervous system), discontinue Invia NPWT therapy to help minimize sensory stimulation
and seek immediate medical assistance.
– Wounds that involve an enteric fistula.
– Use near vagus nerve (bradycardia).
– Circumferential dressing application.
