5.1 FLOW-i Anesthesia system
The FLOW-i is a software controlled circle
system for anesthesia. It features several
components distinguishing it from other
anesthesia systems; gas modules regulating
fresh gas flow, the volume reflector and the
injector based vaporizer.
The volume reflector replaces the 'bag in
bottle' used in many traditional systems. It has
a fixed volume of 1.2 liters and no moving
parts. Gas flow is regulated by the reflector
gas module. This facilitates precise control of
gas flow and pressure during automatic
ventilation.
The Vaporizer works with an electronic based
injector technology capable of operating at
low tidal volumes. This allows for fresh gas to
be led directly through the vaporizer chamber
and be mixed with the anesthetic agent.
Changes made in agent concentrations will
therefore be instantaneous. The vaporizer
technology also enables high agent
concentrations at high fresh gas flows, i.e. up
to 20 l/min.
5.1.1 Tidal volume delivery
The tidal volume delivered to the patient
comes from two sources: the fresh gas flow
and exhaled gas in the volume reflector
pushed back towards the patient by the
reflector gas module. Refer to page 72 for a
schematic view.
When the part of the tidal volume delivered
from the volume reflector exceeds one litre,
gas from the reflector gas module may pass
through the volume reflector and add oxygen
to the breathing system. This will trigger the
'Leakage' alarm.
In these situations, the oxygen concentration
will increase and the agent concentration will
decrease. However, ventilation will always be
maintained.
The situation can be corrected by increasing
the fresh gas flow.
Carefully monitor displayed gas measurements
when using low fresh gas flow settings and
high tidal volumes.
