Ambient Oxygen Deficiency Monitor

This O2 Oxygen Deficiency Monitor is a compact gas monitoring system that's ideal for the continuous monitoring of the MRI Magnet Room where low oxygen levels may pose a hazard to patients and personnel. Unlike electrochemical sensor cells the Air check O2 zirconium cell provides stable oxygen readings even in areas where temperature, barometric pressure and humidity levels are changing.

  • 10 + years Sensor Life
  • No Calibration Required
  • No Maintenance Zirconium Cell
  • No Drift due to Environmental or Temperature Changes
  • Local Display, 4-20mA Analog Output
  • Integral Computer Controlled Electronics
  • Ce EN 61326-1:2006. EMC - Emission, Immunity

The Air check O2 Deficiency Monitor does not drift or loose sensitivity when the weather or temperature changes. The electronics are housed in a Nema 4X housing or optional EX for hazardous areas.

 

Optional Accessories include a Remote Display for the control room so that the MRI Tech can see what the Oxygen reading is without going into the magnet room. And a warning alarm and flashing light.

Documented Accident Cases Involving Non-MRI Safe Equipment

Source: MDR Database
Access Number: M409350
Report Type: Serious Injury
Date FDA Received: 09/17/1993

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.

 

Documented Accident Cases Involving Non-MRI Safe Equipment

Source: MDR Database
Access Number: M161069
Report Type: Serious Injury
Date FDA Received: 11/11/1988

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.
