Monitoring Via LifePort Kidney Transporter Outer Display
The LifePort Kidney Transporter Outer Display provides comprehensive information on the status of the
pumping procedure during perfusion, providing the following information:
•
Pressure
—these are the actual systolic and diastolic pressures of the perfusion process, as the
LifePort attempts to achieve the systolic pressure you have set. The systolic value is often lower
but should never be higher than the set pressure.
•
Flow
—is the volume of perfusate moving through the kidney over time. Flow changes, depending
on how the kidney is responding to the pumping. This value is expected to increase over time, as
the kidney vasodilates, thus allowing the set pressure to deliver a growing flow rate.
•
Resistance
—is the force required to pump perfusate through the kidney. This value is expected
to decrease, as kidney “loosening” provides less and less resistance to the pumping, over time.
Resistance and Flow are inversely proportional.
•
Temperature
—is the temperature of the ice bath and/or of the perfusate, as measured in the
Bubble Trap prior to entering the kidney. The ice bath value will increase as the ice melts,
prompting the user to add more ice. An audible alert is triggered and perfusion stops when
temperatures reaches 8°C (an audible alert occurs at 5°C). The trap value increases as ice bath
values increase and is only displayed during active infusion.
Press the
PLOT/CLEAR
button on the far left side of the display panel to temporarily display trending
data for flow and resistance.
The far right side of the Display Panel provides a range of ID, error and functional information.
•
Current Mode of Operation
—the upper left corner tells LifePort Kidney Transporter’s current
mode of operation, corresponding to the controls on the top of the unit:
INFUSE
,
STOPPED
,
PRIME
or
WASH
.
•
Battery vs. AC Power
—the icon in the upper right corner tells whether LifePort Kidney Trans-
porter is operating on AC or battery power.
NOTE:
If the unit is connected to a power source but is not operating, the unit is charging and
the front panel shows an “electric plug” icon.
•
Organ and Device ID Information
—is displayed in the far right panel when no errors are
present.
•
Errors
—are displayed in the far right panel, accompanied by an audible alert. In addition, the
field affected by the error flashes its information in yellow or red.
For complete information on resolving errors, see
Error Message Explanations
on page 51.
The number to the left of the battery icon provides infuse time, telling how long LifePort
Kidney Transporter has been pumping the kidney. The timer will start as soon as Infuse Mode
has been pressed for the first time and will continue keeping track of the time when LifePort
Kidney Transporter is in Infuse Mode.
