In this video, Dr. Zelken explains the PRO-NOX machine. This device allows patients to achieve a degree of analgesia during procedures like CO2 laser peels, light surgery, and other surgical and nonsurgical interventions. In many cases, this machine can replace the need for oral medications that require a driver to return home. The PRO-NOX allows us to achieve a degree of comfort that is reversible and self directed. We have used this technology in our practice for about 1 year and feel that it is not only safe, but patients love it, and it allows historically uncomfortable procedures to be performed with relative ease and speed.
