A central controller may be coupled to the plumbing system. The central controller may be operable for: initiating the cryotherapy session within the chamber with a cryogenic gas flowing through the plumbing system for cooling the chamber to a first temperature; determining if the first temperature has been reached within the chamber; determining if a check-in command has been received for the cryotherapy session; and stopping the cryotherapy session after a predetermined period of time. The central controller may also monitor a cooling rate for the chamber and a heater associated with the cooling rate. ## Claims ### Claim 1 A method for automatically producing and monitoring a cryotherapy session within a chamber comprising: receiving input for a first temperature for the chamber associated with the cryotherapy session within the chamber; initiating a pre-cooling session for cooling the chamber to a second temperature which is different than the first temperature, the pre-cooling session comprising automatically activating a first remote control valve and a second remote control valve such that cryogenic gas flows into the chamber, and automatically activating a cryogenic heater when needed to keep the cryogenic gas at a predetermined temperature as the cryogenic gas exits a first nozzle and a second nozzle positioned within the chamber; determining if the second temperature has been reached in the chamber; deactivating the first and second remote control valves in response to determining that the second temperature has been reached in the chamber; initiating the cryotherapy session within the chamber with the cryogenic gas for cooling the chamber to the first temperature, the cryotherapy session comprising automatically activating the second remote control valve, and automatically activating the cryogenic heater when needed to keep the cryogenic gas at a predetermined temperature as the cryogenic gas exits a third nozzle positioned within the chamber; determining if the first temperature has been reached within the chamber; determining if a cooling rate for the chamber is being met; and determining if an overheat condition for the cryogenic heater exists during the pre-cooling session and the cryotherapy session. ### Claim 2 (depends on 1) The method of claim 1, further comprising determining if a pressure for a cryogenic fluid that transforms into the cryogenic gas is within a predetermined range. ### Claim 3 (depends on 1) The method of claim 1, further comprising: determining if a stop command has been received for the cryotherapy session; and determining if a check-in command has been received for the cryotherapy session. ### Claim 4 (depends on 1) The method of claim 1, wherein receiving input for the first temperature comprises receiving input through a touch-screen display device. ### Claim 5 (depends on 1) The method of claim 1, further comprising determining if a predetermined time limit associated with the cryotherapy session has expired. ### Claim 6 (depends on 5) The method of claim 5, wherein if the predetermined time limit associated with the cryotherapy session has expired, then stopping the cryotherapy session. ### Claim 7 (depends on 3) The method of claim 3, further comprising determining if a predetermined time limit associated with the check-in command has expired. ### Claim 8 (depends on 5) The method of claim 5, wherein if a predetermined time limit associated with the check-in command has expired, then stopping the cryotherapy session. ### Claim 9 (depends on 1) The method of claim 1, further comprising displaying a plurality of different cryotherapy sessions that are selectable. ### Claim 10 A system for automatically producing and monitoring a cryotherapy session within a chamber comprising: means for receiving input for a first temperature for the chamber associated with the cryotherapy session within the chamber; means for initiating a pre-cooling session for cooling the chamber to a second temperature which is different than the first temperature, the pre-cooling session comprising the means for initiating the pre-cooling session automatically activating a first remote control valve and a second remote control valve such that cryogenic gas flows into the chamber, and the means for initiating the pre-cooling session automatically activating a cryogenic heater when needed to keep the cryogenic gas at a predetermined temperature as the cryogenic gas exits a first nozzle and a second nozzle positioned within the chamber; means for determining if the second temperature has been reached in the chamber; means for deactivating the cryogenic heater and the first and second remote control valves in response to determining that the second temperature has been reached in the chamber; means for initiating the cryotherapy session within the chamber with the cryogenic gas for cooling the chamber to the first temperature, the cryotherapy session comprising the means for initiating the cryotherapy session automatically activating the second remote control valve, and the means for initiating the cyrotherapy session automatically activating a cryogenic heater when needed to keep the cryogenic gas at a predetermined temperature as the cryogenic gas exits a third nozzle positioned within the chamber; means for determining if the first temperature has been reached within the chamber; means for determining if a cooling rate for the chamber is being met; and means for determining if an overheat condition for the cryogenic heater exists during the pre-cooling session and the cryotherapy session. ### Claim 11 (depends on 10) The system of claim 10, further comprising: means for determining if a stop command has been received for the cryotherapy session; and means for determining if a check-in command has been received for the cryotherapy session. ### Claim 12 (depends on 10) The system of claim 10, wherein the means for receiving input for the first temperature comprises a touch-screen display device. ### Claim 13 (depends on 10) The system of claim 10, further comprising means for determining if a predetermined time limit associated with the cryotherapy session has expired. ### Claim 14 (depends on 13) The system of claim 13, further comprising means for stopping the cryotherapy session when the predetermined time limit associated with the cryotherapy session has expired. ### Claim 15 (depends on 11) The system of claim 11, further comprising means for determining if a predetermined time limit associated with the check-in command has expired. ### Claim 16 (depends on 15) The system of claim 15, further comprising means for stopping the cryotherapy session when a predetermined time limit associated with the check-in command has expired.
