Low clinical suction is a consistent frustration for surgery and maintenance
personnel.Clinical suction represents a very important tool in all surgical procedures,
as well as, post surgery recovery. Maintaining minimum flow of each vacuum station inlet is a critical part of a prudent preventative
maintenance program. Periodic decontamination of your vacuum station inlets and piping is a necessary practice to insure optimum
“Piping shall be sized such that 3 SCFM (standard cubic feet per minute) can be evacuated
through any one station inlet without reducing vacuum pressure below 12 in. Hg at an adjacent station inlet.”

The Induction Procedure •Locate the 50cc syringe and vinyl tubing and obtain
a vacuum system
•Place inlet adaptor on the vacuum system inlet.
the vinyl tubing to the adaptor.
•Fill the syringe with Flowzyme.
•Attach the filled syringe
to the vinyl tubing and allow suction to pull Flowzyme
into the vacuum system.
•Remove the inlet
adaptor as soon as the syringe is empty.
•Let Flowzyme sit in the inlet and piping for 10-20 minutes.
•Allow vacuum suction to draw for 5 minutes.

For totally blocked
•Apply pressure with an empty syringe to the inlet.
•That pressure should alleviate restriction

Dental Induction procedure
Use this procedure for initial cleaning or for weak vacuum suction:
•Mix 2 oz of Flowzyme-Dental in 1 gallon of water
•Use 1 gallon of the above solution to flush each system
•Disconnect the high volume evacuation and saliva ejector lines and place open end in the Flowzyme Dental solution.
•Aspirate the solution through the line, 1 gallon each.
•Dispose of the residue into the cuspidor.
