Btm Function; The Btm Data Screen Features - Fresenius Medical Care 2008T Operator's Manual

BTM function

The BTM has two primary functions – to regulate the patient's temperature (energy) and to
use temporary changes in dialysate temperature to determine the extent of recirculation at the
blood access site.
Table 27 – The BTM Data Screen Features
Feature
Note: When the 2008T hemodialysis machine is first turned on, the small display on the
BTM will indicate 1107. This is a normal event and can be cleared by pressing the Up 
(Error) and Down  (Result) keys on the BTM module at the same time.

Function
This area will display "Recirculation" when a recirculation test is
being done. When there is no control program, it will read
"Monitoring." It will read "Temperature" or "Energy" when in a
temperature or energy control mode.
When performing a recirculation measure, the data box will
display the T set value that the dialysate will reach.
When in a temperature control mode, this area will display the
rate of temperature change prescribed to warm or cool the
patient in °C/h.
When in an energy control mode, this display will indicate the
energy flux to or from the patient in kilojoules per hour (kJ/h).
This displays the arterial bloodline temperature as reported by
the BTM module.
This displays the venous bloodline temperature as reported by
the BTM module.
The table above the graph will display up to 3
recirculation values. This graph shows the
arterial temperature in red and the venous
temperature in blue. During recirculation tests
the temperature will show changes for a short
period of time. The vertical dotted line
indicates the scheduled end of treatment.
