The CryoProbe uses Nitrous Oxide.
You have about 100 seconds of gas flow per 8 grams of nitrous oxide. The freezing penetrates tissue at a rate of about 1mm per 5 seconds. So if you have a lesion that’s 2mm deep, you would need 10 seconds of continuous gas flow, depending on the diameter of the treatment area. You can expect to treat 1-3 patients per 8 grams of nitrous oxide.
As an example, an 8 gram cartridge costs about $7. If you treat 2 patients with that cartridge, that’s about $3.50 per patient.
Since there are so many different treatment options, it’s hard to give an exact price. On average, you’ll find you charge about $75 – $100 per customer. If a customer comes in specifically for treatment with the CryoProbe, you’ll want to charge more per lesion. If on the other hand, they come in for something unrelated and you find a lesion to remove, you might charge less as an “add-on” service.
Nitrous Oxide delivers a temperature of -127°F/-89°C. It will create an in-tissue temperature of between -122°F/-50°C within 10 seconds, largely enough for all benign lesions.
Warts, skin tags, solar lentigo, pigmented spots, actinic keratoses, seborrheic keratoses, Hemangioma, molluscum contagiosum, condyloma, plantar warts, and more…
For smaller treatments, one treatment is usually enough (age spots, skin tags, actinic keratoses). Warts will typically need a second and sometimes even a third treatment. Treatments should be spaced roughly 2 weeks apart.
When treating patients with darker skin, it is important to decrease the treatment times to reduce the chances of hypopigmentation.
There is no need for specific aftercare other than protecting the treated area. The patient can resume normal activity immediately but may want to use sunscreen to protect the area. The only other precaution is to tell the patient not to pick at or scratch the treated area. Picking or scratching may create an open wound which could result in scarring.
An unopened cartridge has a shelf life of 24 months.
