Safety

Before working in any GE Healthcare MR suite or performing any GE Healthcare service procedure, you must:

  • Have read and understood all hazard conditions and safety requirements in the latest revision of the GE Healthcare MR Service Safety Manual (5452735).
  • Have successfully completed all relevant GE Healthcare Environmental Health and Safety (EHS) courses (or for non-GE employees, equivalent workplace training courses).
  • Comply with all site-specific training and workplace safety requirements.

If you have any safety concerns at any time, do not begin work or immediately stop work and move to a safe location. Immediately contact your supervisor or site safety officer for instructions on how to proceed.

The pneumatic patient alert system is a stand-alone system that allows the patient to alert the operator even when the console volume is turned down. Patient-to-operator contact is accomplished when the patient compresses a hand-held squeeze bulb that activates an audible and visual alarm near the operator. Either a pulse or steady audible tone can be selected at the control box. The operator must reset the control box to stop the alarms.

Procedure

  1. Connect the squeeze bulb to the patient table if it is not already connected.
  2. Make sure that the green LED on the control box is lit.

  3. Set the control box steady/pulse switch to Pulse.
  4. Compress the squeeze bulb slowly until fully collapsed.
  5. Make sure the red LED on the control box is lit and the audible alarm is emitting a pulsating tone.
  6. Set the control box steady/pulse switch to Steady.
  7. Make sure the red LED on the control box remains lit and the audible alarm is emitting a steady tone.
  8. Press the Reset button on the control box.
  9. Make sure the red LED on the control box and the audible alarm are off, but the green LED remains lit.
  10. Examine the squeeze bulb-tubing interface for wear. If the tubing becomes separated from the squeeze bulb (for example, gets caught in the table), reinsert the tubing onto the coupler, otherwise replace with appropriate FRU.
