4.3.1 Lung

Protective
Flow Rates
Once the lung has reached
30
o
C , use the percent of
calculated flow rate chart to
begin adding flow in a stepwise
fashion according to the chart.
NOTE: For a double lung, the
maximum flow rate is 40% of cal-
culated cardiac output for the
donor. The chart indicates which
percentage of the maximum
(40%) rate should be flowing into
the lung. For example, at 10
-
20
minutes when the lung is 30
o
C,
the Percent Calculated Flow rate
indicated in the chart is
‘20%.’
This is actually 20% of the 40%
max, or 8% of maximum flow.
For a single right lung, the maxi-
mum flow rate is 24% and for a
single left lung, the maximum
flow rate is 16%.
According to the chart, at
50
-
60 minutes, the lung is at
maximum flow rate of 100%
Calculated Flow, which, for a
double lung, is
40% of calculated
CO.
Double Lung Perfusion:
Max Flow Rate= 40% CO
Single (Rt) Lung Perfusion:
Max Flow Rate= 24% CO
Single (Lt) Lung Perfusion:
Max Flow Rate= 16% CO
