Precautions
The metal sensor is robust and can withstand severe shocks and vibrations. However,
it cannot be recovered if damaged by sharp objects or overpressure, for instance by
squeezing the tip using the forefinger and the thumb.
The silicone coating on the sensing area allows a small amount of water absorption.
But if the water absorption lasts for an hour or more, the baseline may drift several
mmHgs. In this case, put the device in water or saline solution for a few hours to
stabilize before use.
Liquids entering the back of the sensor will cause damage to the sensor. Cutting on
the outer coating should be avoided and repaired immediately once detected. You
may return it to the manufacturer or apply a temporary repair using a suitable
silicone sealant to the damage.
The most common reason for failure of the ICT/B pressure transducer is physical
damage to the device's silicone catheter and/or tip. The cuts are usually caused by
sharp bone chips or edges and are not always visible to the naked eye. If such
damage remains undetected, fluids may enter the device and damage the sensing
parts.
