Delivery
(measured
dose):
At the point of sampling at the
patient Y-piece the accuracy is that of
themonitoringsystemabove.
Delivery(with
respect to
set-point):
Thesystemwillservethedelivered
concentrationtotheset-pointsubjectto
theowfromtheventilator,seesection
“MaximumNODoseDelivery”belowfor
the set point range.
Once the measured dose and set point
agree then the accuracy w.r.t. the set
point is that of the monitoring system.
Until the set-point is reached then
the accuracy is that of the difference
between set-point and measured dose
plus the accuracy of the monitoring
system.
