Abstract
A method of cleaning an endoscope in a computer-controlled washer/disinfector comprising the steps of connecting each lumen of an endoscope to a fluid distribution system for selectively conveying pressurized air or pressurized fluids through lumens in an endoscope; identifying the type of endoscope to be cleaned in said washer/disinfector; determining a blockage threshold flow coefficient for each lumen for said endoscope to be cleaned; pressurizing each lumen in said endoscope individually and determining an actual flow coefficient through said lumen; determining whether said endoscope is suitable for cleaning by comparing said actual flow coefficients for a lumen in said endoscope to said blockage threshold flow coefficient for said lumen; and determining whether a connection to a lumen in said endoscope is properly connected based upon said flow coefficient through said lumen.
