down. It is obligatory to maintain this default setting. Increasing the maximal flow
rate allowed from the wound may eliminate control of acute bleeding.

Alarms Setting: Alarms are pre-set as default to audio & visual alarms. Any alarm
condition will be indicated by audio (a repetitive beeping sound) and visual (A
flickering triangle symbol in the middle of the display screen and an indication
LED) alarms. Changing this pre-setting should be considered carefully. Change of
alarms settings may prevent from the care-giver the detection of critical indications
regarding the vacuum treatment.

Never leave a wound covered for an extended time without effective negative
pressure. As the Vcare

®
system is operating, fluids are discharged and
constantly evacuates from the wound. Once the vacuum is halted, the system is at
risk of becoming occlusive, which might lead to infection.

Wound dressing must be replaced according to the clinical guidelines or
physician’s judgment in order to prevent super infection to the wound.

Constant efficient negative pressure should be applied to the wound in order to
avoid bacterial overgrowth and super-infection. If vacuum is ineffective for over 30
min, aeration of the wound by removal of occlusive dressing or other form of
ventilation should be considered.

The Vcare

®
system should not be used in cases with apparent or suspected
anaerobic infection.

Negative pressure may exacerbate uncontrolled bleeding. All precautions should
be taken in order to avoid uncontrolled bleeding and the immediate cessation of
RNPT in case of excessive bleeding should be executed.

Avoid high negative pressure during the early stage of trauma treatment.

Severe, life-threatening bleeding may result from the application of vacuum in
treatment of acute trauma, immediately after surgery, at early stages following
debridement of wounds, in patients treated with anticoagulants or suffering from
hematological disorders.

Setting high values of negative pressures may induce ischemia and may
aggravate clinical ischemic conditions such as in peripheral vascular disease,
diabetic leg, and traumatized tissue.

Excessive topical pressure may lead to compromised blood circulation and
impairment of wound healing.
