Designed for simplicity in installation and use, this ambient Oxygen Monitor plugs into any 120
VAC wall outlet for instant area monitoring in the MRI suite.
A cryogen leak in the MRI suite can be very dangerous. Even though the gas itself is not toxic,
it can displace oxygen in the air and cause asphyxiation before the people in the room are aware
of what is happening. OHSA has determined that "oxygen levels [in the air] below 19.5% are
inadequate for an entrant's respiratory needs... Victims of asphyxiation often are unaware
of their predicament until they are incapable of saving themselves or even calling for help."

Magmedix offers, at a very attractive price, a wall-mounted atmospheric oxygen monitor
that is completely safe within the MRI suite when mounted on the wall, and will not cause
any imaging artifacts. Should the level of oxygen in the room drop below 19.5%, the monitor
sounds an alarm.
During routine cryogen fills, or in the event of a magnet quench, it is important to maintain
adequate ventilation. Further more, room air should be closely monitored to safeguard
against the health hazards associated with the displacement of oxygen.
Please note:The monitor's power
pack is magnetic and must be kept a safe distance from the magnet.
Magmedix recommends that the oxygen sensor with-in the Monitor be
Calibrated every 3 months and the sensor be changed every two years.

The Magnet quenched and the vent system failed, releasing Helium into the
Magnet room. The Tech could not open the door because the room pressurized.
The Tech broke the observation window to gain access to the room.
The PT was removed and taken to the ER, where oxygen was administered.
The PT exhibited slurred speech and was disoriented. The venting
system is being inspected.

It was reported to company, that during Magnet quench the venting system failed, causing Helium to vent into scan room.
The Tech strained his back when he was removing the PT from the scan room. There was no PT injury. Company service personnel
report that the Tech involved in the incident had been trained in the proper procedure for removal of PTS in an emergency and
that this procedure for removal of PTS in an emergency and that this procedure was not followed.
