T1/T2 Behavior - New
XP Systems differ from earlier ZOLL Heat Exchange Systems in their T1/T2
behavior i.e. in how the Primary and Secondary Temperature probes are
monitored and alarmed.
WARNING! Dislodged Foley Catheter Temperature Probe
The System can detect when a patient temperature probe is dislodged
suddently from the patient.
However it is possible for the Foley catheter patient temperature probe (T1) to
become dislodged from the bladder to rest on the perineum or within the fold of
the thighs. In such a position the System may not detect the dislodgement
from the patient and will underestimate the patient’s core temperature. As a
result the System may inappropriately heat the patient.
Failure to use a second temperature probe may result in patient injury.
First Use Warning – No T2 Probe
For each time the System is powered on:
1. The System will check to see if the Primary (T1) and Secondary (T2)
Temperature Probes are present. The System will enter STANDBY
without probes being present. The System will not enter RUN unless the
T1 probe is present.
2. When the System is first put into RUN, it will check to see which probes
are present.
3. If there is no T2 present, the System will ask the User to verify that this is
intentional. See image below.

The System remembers the User’s preference.
