Description
Pressure Gauge /
Displays the working pressure of the argon and helium gases within the system�
Gas Indicator
NOTE: The Visual-ICE Cryoablation System contains internal regulators that regulate the gas
pressure to appropriate working limits� The pressure displayed on the Gas Indicator is the
internal, regulated pressure and not the cylinder gas pressure�
Pressing the Pressure Gauge toggles the pressure gauge to display the estimated procedure
time remaining before the gas cylinders are depleted� The estimated times are displayed in
hours:minutes:seconds� During needle testing, both pressure gauges display the estimated
time remaining� The initial estimates during needle testing are based on the assumption that
all connected needles are operating simultaneously at 100 % freeze intensity�
The Gas Indicator updates in real time as needles are disconnected or additional needles
are connected and as the freeze intensity is adjusted� Pressing the Gas Indicator toggles the
display back to Pressure Gauge�
