8.1.7 Cleaning the probe
To clean the IRMA™ probe, use a cloth moistened with alcohol or
isopropyl alcohol (< 70%).
CAUTION
Do not sterilize the IRMA™ probe or submerge it in liquid.
CAUTION
The IRMA™ airway adapter is a non-sterile device. Do not autoclave it, otherwise it
will be damaged.
8.2 Measurement using the sidestream technique
Measuring the CO
2
concentration using the sidestream technique involves
the continuous suction of a small amount of air which is routed to the
MASIMO ISA™ detector via a thin tube. This is where the measurement
occurs. The benefit of this approach is that the weight near the ETT is not
increased, reducing the risk of extubation. For this reason, this technique
is particularly popular in pediatric and neonatal settings.
