2 MIST Therapy ® System Therapeutic Ultrasound Ultrasound Applications High Intensity Ultrasound Low Intensity Ultrasound MHz High Frequency Thermal Sports Medicine Physical Therapy Diagnostic Imaging Fetal Monitoring kHz Low Frequency Debridement Söring, Misonix Wound Healing MIST Therapy* MIST Therapy Is Different From Other Ultrasound Devices

3 MIST THERAPY IS AN EVIDENCE BASED ADVANCED MODALITY THAT : 1. Promotes Wound Healing 2. Promotes New Cell Growth 3. Removes Bacteria 4. Cleans & Debrides 5. Painless

4 Promotes Wound Healing Promotes Wound Healing “The MIST Therapy System produces a low-frequency, ultrasound-generated mist used to promote wound healing through wound cleansing and maintenance debridement by the removal of yellow slough, fibrin, tissue exudates, and bacteria.” “The MIST Therapy System produces a low-frequency, ultrasound-generated mist used to promote wound healing through wound cleansing and maintenance debridement by the removal of yellow slough, fibrin, tissue exudates, and bacteria.”

5 APWT Promotes New Cell Growth APWT Promotes New Cell Growth MIST Therapy is a healing device for wounds and uses acoustic pressure to stimulate new cell growth. The cell walls of healthy human tissue cells, when put under stress will proliferate at a much faster rate. Studies show that when the acoustic pressure from MIST Therapy hits healthy cells, they become elongated and deform, causing a greater mitotic response of new healthy cells.

6 Removes Bacteria Removes Bacteria “Mist Therapy also uses acoustic pressure to remove bacteria. Unlike healthy tissue cells, the cell walls of bacteria are hard, like egg shells, and studies have shown that bacteria cells break apart and are destroyed when the acoustic pressure from a MIST Therapy treatment comes in contact with them.” “Mist Therapy also uses acoustic pressure to remove bacteria.

7 Cleans & Debrides Cleans & Debrides “Although not a primary debridement tool, MIST Therapy helps to remove yellow slough, fibrin, necrotic tissue, and bacteria. This is especially helpful and beneficial in the removal of biofilm that often “stalls” the healing process in wounds.” “Although not a primary debridement tool, MIST Therapy helps to remove yellow slough, fibrin, necrotic tissue, and bacteria.

8 Painless Painless “Since MIST Therapy is a noncontact and a nonthermal ultrasound device, it is also a painless procedure. It is one of one six products and one of only three devices cleared by the FDA allowed to say in its clearance statement that it promotes wound healing.” “Since MIST Therapy is a noncontact and a nonthermal ultrasound device, it is also a painless procedure.
