All cryogenic liquids are gases at normal temperatures and pressures and must be cooled below room temperature before an increase in pressure can liquefy them. Cryogens have boiling points below -150°C (- 238°F), although carbon dioxide and nitrous oxide have slightly higher boiling points and are often included in this category. Different cryogens become liquids under varying conditions of temperature and pressure, but all have several potential hazards in common, which are outlined below The daVinci SM Cryogen Management System is Cool Pair Plus's Remote Magnet Monitoring system..

As this point-of-care (POC) MRI scanner uses a permanent relatively weak magnet, there's no need for cryogens used to cool the magnet in traditional MRI systems Every MRI magnet room with a superconducting magnet should have an oxygen monitor. These devices measure the percentage of O 2 in the air and sound an alarm when the level falls below a set threshold. These devices are needed because leaks in the venting system that handle the boil off of cryogens could create a situation where excess N 2 or He in the room air would deplete the percentage of O.
