PITFALLS & PEARLS
Filling the Cervical Seal with air instead of sterile fluid.
Removing the device while vacuum is still connected — disconnect first, every time.
Forcing insertion against resistance.
No flow or tone change: check for an air leak or incomplete seal coverage.
Losing track of insertion time — write it down; 24 hours is the maximum.
