Questions Answers
Is the ICT/B a single use device? No, it can be reused.
If it is damaged, what shall we do? Disinfect first. Then, send it together with the
purchase order back to the manufacturer for
repair.
Does the air used for checking the zero get
into the patient? No. Air used for checking the zero stays in the
fine lumens and tip of the ICT/B until the
syringe is removed.
What happens if we autoclave the ICT/B? It must be sent to the manufacturer for repair.
We inject air to check the zero but the
baseline on the scope always returns to ICP
even if we leave the syringe attached. What’s
the reason? There is a leak in the catheter or sensor tip.
Remove, wipe clean with alcohol and then
disinfect. Return the device to the
manufacturer for repair.
Readings were taken with the syringe left
attached until we noticed it. Can we rely on
these readings? No. They are incorrect. All pressure readings
must be made with the proximal female luer
open to atmosphere.
A new staff injected water into the luer.
Though we found it immediately, some water
went into the ICT/B. Is the device ruined? Probably not. Return it to the manufacturer for
repair.
Why is the ICT/B damaged if we perform
ETO disinfection with the luer blocked? When you plug the luer you are sealing the
internal lumens at normal atmospheric
pressure. Part of the ETO cycle is a partial
vacuum. Thus, the trapped air at atmospheric
pressure will expand and rupture the balloon.
