DecontaminationQuestion 20 of 100
A lumened suction instrument arrives in decontamination. Which cleaning practice is correct?
a.Soak the device for one hour and rely on the soak to clear the lumen
b.Run the device through the ultrasonic cleaner only, since brushes cannot reach the channel
c.Flush the lumen with a high-pressure air gun before any liquid contacts the device
d.Flush the channel with detergent solution and brush it with a brush of the correct diameter and length, then rinse thoroughly
Explanation
Lumens require mechanical action delivered by a brush that actually contacts the internal wall along the full channel length, followed by thorough flushing and rinsing. A brush that is too small does not touch the walls and one that is too large cannot pass. Soaking alone, ultrasonic alone, or blowing air through a dry contaminated channel will not remove adherent biofilm and soil.
