2.2.5 Monitoring and Sensors
WARNING!
n
The water quality can influence the ice sensors which, in turn, can influence
ice formation. Perform a visual inspection of the actual ice size and adjust the
setpoint ice block size should the actual ice size differ from the setpoint size.
n
The following parameters must be monitored continually by an independent
monitoring and alarm system during application.
- Temperature of the patient
- Blood temperature in the perfusion system
- Contact surface temperature of the warming/cooling blanket
n
The external temperature sensors are intended for operating the HCU 40 in
gradient mode. They must not be used for measuring the patient's core body
temperature, and their use does not replace independent, external monitoring
of the blood temperature in the perfusion system.
n
The precision of external temperature measurement depends on the
temperature sensor and the disposable.
n
External temperature sensors must not be autoclaved.
n
Only use the external temperature sensors, with shielding, listed under
"Supplies" for the HCU 40.
n
When operating the unit in gradient mode, the user can set temperature
limits. An alarm is given if the temperature either falls below or exceeds the
limit value.
n
The temperature limits must be set on the basis of physiological criteria.
n
If an alarm occurs, the setpoint and actual temperatures of the water and the
patient's temperature must be checked.
n
After data have been input by the user, the HCU 40 must not be switched off
immediately, as saving the data may take up to 10 seconds.
2.2.6 Extended Applications
WARNING!
While performing longer normothermal applications, avoid abrupt hypothermia,
which could endanger the patient's health, by employing the following measures:
n
Do not add any ice;
n
