Placing the Regulator on an E-cylinder

Introduction to E-cylinders

• E-cylinder Usage: Standard type used in hospitals.
• Color Coding: Typically green for oxygen.
• Dust Cap: Prevents dust and contaminants from entering.
• Material: Aluminum, but contains steel, hence not suitable for MRI rooms unless MRI-approved.

Safety Precautions

• MRI Safety: Do not bring non-MRI-approved tanks into MRI rooms.
• Lifting Caution: Do not lift the E-cylinder with one hand for safety.

Pin Index Safety System (PISS)

• Positioning: Holes are in 2 and 5 positions on the cylinder.
• Main Hole: Oxygen outlet.
• Dimple Lock: For the lock screw.
• Regulator Attachment: Lock screw secures the regulator.
• Pins and Bordon Gauge: Used to ensure correct attachment.

Regulator Functions

• Fixed Orifice: Preset flow rates, not adjustable between levels.
  • Typical flow rates: 0.12, 0.5, 1, 1.5, 2, 3, 4, 6, 8, 10, 12 liters per minute.

Procedure for Attaching the Regulator

1. Prepare the Tank:
   • Crack open the tank to release initial gas pressure.
   • Ensure dust cap is removed.
2. Align and Attach Regulator:
   • Align the two pins with the cylinder holes.
   • Screw down the regulator finger-tight.
   • Give a slight additional twist to ensure secure attachment.
3. Open the Cylinder:
   • Check pressure (e.g., 200 psi) and listen for hissing to ensure a good seal.
4. Turn Off and Bleed the Cylinder:
   • Turn the cylinder off when done.
   • Bleed the cylinder to empty it.
   • Detach the regulator after ensuring it is not too tight.

Conclusion

• Safety Reaffirmation: Ensure proper seal and secure attachment to prevent leaks.
• Detachment: Proper procedure for safely removing the regulator from the cylinder.
