For information on disassembly and cleaning, see the instructions included
with the Blending Bag Kit or see Cleaning and Maintenance.

Monitoring the Oxygen Supply Flow in the Oxygen Blending Bag
The following graphs can be used to determine the required oxygen supply
flow for the patient. There are two graphs – the first one is for when there is
no PEEP; the second is for when PEEP is added.
The oxygen supply flow of the Oxygen Blending Bag Kit is determined
according to the desired percent of oxygen enrichment as well as the minute
volume of the patient.
The oxygen blending bag is not a calibrated oxygen mixing
device. It requires the use of oxygen monitoring, to verify the
level of oxygen enrichment. The information in these graphs
should be used as a reference only.
To use the graphs:
1. Choose the appropriate graph, based on whether you are ventilating with
or without PEEP.
2. Choose the Desired % of Oxygen Enrichment listed at the bottom of the
graph.
3. Follow your selection up vertically until it meets with the line that is equal
to the minute volume of the patient (i.e. flow 10 L/min).
The delivered minute volume of the patient can be read from the
alarm setting display window, when it is not blinking.
4. Move horizontally to the left and identify the estimated oxygen supply
flow (L/min) needed.
5. Set the flow meter to the oxygen supply flow indicated.
