Table 9-9 Pressure values
Having the system compliance (Csys) and ΔP, Anaesthetic Workstation can calculate which
volume (ΔV) has been "consumed" by the system, or, in other words, which volume has not been
delivered to patient.
ΔV = Csys x ΔP
The Anaesthetic Workstation increases the volume to be delivered by the value ΔV.
V
T
corr = V
T
+ ΔV
The Anaesthetic Workstation repeats this procedure during each breathing phase so that the V
T
delivered to the patient gradually approaches the set V
T
. This procedure is completed as soon as
the plateau value stops changing (±0.5 cmH
2
O).The displayed flow and the resulting values (for
example, MV) are updated accordingly.
