Magnetic Resonance Imaging (MRI) facilities have the same thing in common, helium. Helium is used as part of the cooling process for a MRI magnet. PureAire Monitoring Systems Oxygen Monitors are becoming the newest safety product amongst MRI users, thanks to its 10 + year sensor. PureAire’s sensors do not require maintenance, or require replacement parts. Helium is a nontoxic, odorless, colorless, nonflammable gas stored in cylinders at high pressure. It can cause rapid suffocation when concentrations are sufficient to reduce oxygen levels below 19.5%. It is lighter than air and may collect in high points or along ceilings. Self-Contained Breathing Apparatus (SCBA) may be required by rescue workers1.

The above statement is from an Air products MSDS sheet. In addition, ACGIH considers Helium a simple asphyxiant. PureAire has been in business for 14 years selling their highly revered O2 Monitors for safety in MRI facilities for physicians, and clients. MRI facilities are beginning to become aware of the dangers associated with helium storage. Clients only have good things to say about our O2 Monitors:

“Thanks again for your support. The oxygen monitors are in their respective locations and are functioning as designed. Nice unit! Everyone thinks they are a great product. The software menu is easy to use and could not be easier to operate.” Dominion Nuclear.

“The O2 monitors are working well and doing a great job!  Alarm relays are configured with the exhaust fan and is triggered a couple of times a day if we have LN2 bottles in the area.  Excellent product, repeatable, and reliable as advertised.”  Gulfstream Aerospace.                                                                                                   

Currently PureAire’s O2 Monitors are being used at MRI facilities around the world. O2 Monitors have been used for over 30 years, though most people are accustomed to using an O2 monitor with sensors only lasting 12-18 months. In addition to, they must be calibrated and maintained to function correctly. PureAire’s 10+ Year O2 Deficiency Monitor is much more reliable, requires no maintenance, and does not need to be calibrated. There zirconium sensor does not have the biases associated with the disposable sensor technology. This means no more false alarms and drifting, and an always-accurate reading.
