The abrupt and drastic lowering of the skin’s surface temperature is called a Thermal Shock.
CRYOFOS delivers intense cold therapy using medical CO2 gas. From its pressurized, liquid state in the cylinder, the gas emerges from the nozzle of the treatment gun as a fine spray hitting the skin at a temperature of -78° C and cooling the treated area to between 2° C and 4° C in under 30 seconds. This abrupt and drastic temperature change, called a Thermal Shock, triggers a neuro-reflexive response in the body.
The stream of gas from the CRYOFOS treatment gun also applies up to 2 bars of pressure to the treatment area. The combination of this pressure and the Thermal Shock is the key to NRS Therapy.
