3.3.5 Single Lung
Cannulation
In the case where one lung is not
available or usable (due to
concerns with infection, etc.), it is
possible to perform the EVLP
technique on only one lung.
Cannulation of the single right or
left lung follows the same proce-
dure as with the double lung with
the following differences:
LA Cannula (cone) should be
shaped according to the diameter
of the available atrial cuff and
connected with a running 4
-
0
polypropylene suture as with a
double lung.
PA Cannula (straight) is intro-
duced into the PA branch and
tied in place with a silk suture.
ET tube cannulation requires a
different approach depending on
right or left lung perfusion.
Right:
preserve a portion of
the trachea to facilitate.
ligation of the ET tube with an
umbilical tape (right bronchus
can be short).
Left
: typically, the left
bronchus extension is long
enough to place and ligate the
ET tube in the correct position.
For a single lung, all three
cannulas (LA, PA and ET) will
come out of the top lid portion of
the XVIVO Organ Chamber.
CAUTION: remember that if
evaluating only one lung, V
T
should be
reduced
by 50% of
calculated. See Section 3.3.11
