Zeltiq Device - What Does the Number on the Machine Represent?

During the zeltiq treatment, there is a number in between the minus and plus arrows on the screen, what’s the number represent? Is the number representing the temperature? Is it the higher the number, the more the fat grabs (powerful) ?

Zeltiq--by the numbers

{{ voteCount >= 0 ? '+' + (voteCount + 1) : (voteCount + 1) }}

The number between the arrows represents suction.  (generally somewhere between 50-70, more commonly 50-60)  This number can effect how much tissue is drawn up in to the machine but how 'good' your results or treatment is not necessarily dependent on a bigger number (i.e. higher numbers like 70 don't mean you'll have better results than 55).  Higher suction can be beneficial in getting the handpiece to 'stick' in some tricky areas but can also result in more bruising after or discomfort during the procedure.

It basically represents the amount of suction that pulls the skin and fat into the cup that cools that fat.  High numbers can pull more fat into the treatment zone, but could result in more bruising or discomfort.  The sweet spot seems to be between 50-70, depending on the patient and the cup being used.  Hope this helps!                      Take care, Dr. Groff

The numbers represent the level of suction on the applicator. The level of suction will vary depending on the area being treated, the pliability of the tissue in the area, and the applicator being used. It does not affect how much fat will be reduced. It is adjusted in order to maintain optimal suction on an area.

The numbers are a gauge of negative pressure, the suction applied to the skin that draws in the skin and fat.  It shouldn't be too excessive nor too weak.  The average is 60 but we adjust it if needed for the fit.

Thank you for your question.

The number you are referring to indicates how much tissue is taken into the chamber. This number is generally between 50-70.  The higher the number doesn't necessarily mean a better result.. sometimes we are treating a more difficult area and the suction needs to be higher.  A higher number may also result in more bruising after the procedure.

I hope this helps.

Coolsculpting works excellent for reducing fat bulges. The machine settings and numerical values have nothing to do with the number of fat cells treated. These settings have to do with the vacuum chamber and the ability to adequately maintain suction and treat the targeted areas.
