Dräger Perseus A500 - Prediction of the Inspiratory O (Optional); Concentration

Operation
102 Instructions for use Perseus A500 SW 2.0n
The anesthetic gas concentration of the currently
delivered anesthetic agent (or of the measured
primary anesthetic agent if delivery is switched off)
is displayed as a color diagram. The
corresponding expiratory concentration is shown
by the color coding for the anesthetic agent.
The previously measured concentrations are
displayed in the left-hand section (A) and the
predicted concentrations in the right-hand section
(B). The predicted concentrations are dependent
on the vaporizer setting, the set fresh-gas flow,
and on various measurements.
Electronically controlled gas mixer only:
During the setting procedure, 2 dotted lines (D) are
displayed for the fresh-gas flow (the so-called
"what if..." function). When the value is altered with
the therapy control, the lines move and show a
preview of the predicted concentration.
Prediction of the inspiratory O2
concentration (optional)
Perseus offers the option of displaying the
predicted inspiratory O
2 concentration in the
breathing gas. This requires the O
2 prediction
option. The FiO
2 prediction parameter field must
be configured in the monitoring area.
The FiO2 prediction is suitable only for patients
with a body weight of more than 30 kg (66 lbs).
The following is displayed:
A Section for the trend
B Section for the prediction
C Current O
2 fresh-gas concentration
D Prediction curve ("what if..." function)
The inspiratory O
2 concentration is displayed as a
line.
The previously measured concentration is
displayed in the left-hand section (A) and the
predicted concentration in the right-hand section
(B). The predicted concentration is dependent on
the set O
2 flow and the measured patient values.
Electronically controlled gas mixer only:
During the setting procedure, a dotted line (D) is
displayed for the O
2 flow (the so-called "what if..."
function). When the value is altered with the
therapy control, the line moves and shows a
preview of the predicted concentration.
WARNING
Risk of incorrect therapy settings
The anesthetic gas prediction is based on
mathematical models and does not provide
individual patient values.
Do not make therapy decisions based solely
on the displayed anesthetic gas prediction.

WARNING
Risk due to incorrect O2 prediction
Therapy decisions should not be made solely
on the basis of a displayed O2 prediction.
