Accuracy specification of the measured CO

partial pressure is according to the
following table (This testing is done according to ISO 21647 clauses 51.101.1 and
51.101.2.).
Accuracy in the presence of interfering gases:
The accuracy specification is maintained to within 4% of the values indicated in the table
above in the presence of interfering gases according to ISO 21647 clauses 51.101.3 and
101.1. The accuracy specification is maintained to within 4% of the values indicated in the
table above in the presence of up to 80% Helium with up to 15% oxygen when tested
according to the procedures defined by ISO 21647.
Respiration Rate Accuracy:
Self Maintenance (SFM) Interval:
Self-Maintenance (SFM) is performed only during measurement mode. The module performs
one or more of the following:
• Ambient pressure measurement
• Auto zero (AZ)
• Flow test
SFM is triggered under the following conditions:
• During the first hour after entering measurement mode, periodically for durations of
typically 10 seconds at a rate which limits the total time consumed by SFMs to less
than 2% of the time in which active measurements are taken. Following the first hour

* At sea level.
** Accuracy applies for respiration rates of up to 80 RPM. For respiration rates above 80 RPM, accuracy is
4 mmHg or
±
12% of the reading, whichever is greater, for EtCO

values exceeding 18 mmHg. This is
tested according to and is compliant with ISO 21647. To achieve the specified accuracies for respiration
rates above 60 respirations/minute, the Microstream FilterLine H Set for Infant/Neonatal
(p/n 006324) must be used. Above 55 degrees C module temperature,
±
1 mmHg or
±
2.5% (whichever is
greater) has to be added to the tolerance of the accuracy specs.
