is only intended for use with, and connection to, the specified accessories and
single-patient use disposables as detailed within this technical guide.

0 – 99.9 %
NO Delivery Range (set point)
Measuring Range
0.6 – 80 ppm (Note the system allows setting at <= 0.5
ppm, accuracy figures below are for >= 0.6 ppm, use of a
lower setting is at customer responsibility)
NO input concentrations 200, 225, 250, 300, 400, 450, 500, 800, 900 & 1000ppm
NO Delivery and Measurement resolution
0.1 ppm
Means of disconnection
Mains power supply plug
Mode of Operation: Synchronous (1.5-50 Ltr/m) or Continuous
Sample Flow Rate:
Approx. 225ml/min
Gas Concentration Detection Principle:
Sealed electrochemical sensor
Accuracy: Monitoring:

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 flow 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.
Manual Mode
Delivery (with
respect to
value advised
by the Dose
Calculator)
Dose calculator, continuous flow.
The delivered dose will be +/-30% of
the figure advised by the onscreen dose
calculator. Monitoring can be used to
determine the actual value.
Intermittent (non-continuous) ventilation.
Accuracy has only been verified with
a continuous flow use. Intermittent
flow accuracy doses values must be
determined by the customer.
