CAUTION. Before beginning the cryoablation procedure, ensure availability of sufficient gas to
conduct the planned cryoablation procedure (reference Section 11.5 for gas purity requirements).
3. Ensure the Gas Indicator (Screen 3‑4) displays the minimum working pressure before initiating a
procedure (Table 4-2). The Gas Indicator should indicate the pressure is within the green range.
If the system detects that the pressure reading for either gas cylinder is less than 50 psi, a
message displays on the Navigation Tool Bar (Screen 4‑8). Connect the gas cylinders to the
Visual-ICE MRI Cryoablation System.

Table 4-2. Working Gas Pressures
Gas Nominal Working Pressure Working Pressure Limits
Argon
3500 psi 3200 – 3800 psi
241 bar 221 – 262 bar
24.1 MPa 22.1 – 26.2 MPa
Helium
2200 psi 1800 – 2500 psi
152 bar 124 – 172 bar
15.2 MPa 12.4 – 17.2 MPa
CAUTION:
• When the gas cylinder pressure falls below the lower working pressure limit, the system
displays an alert message in the
Navigation Tool Bar.
To ensure optimal performance, replace
a gas cylinder if the pressure falls below the lower working pressure limit.
