Rise time (module PN: 115-027545-00)
Measured with a DRYLINE II neonatal watertrap and a 2.5-meter neonatal sampling
line:
<330 ms@90 ml/min.
Measured with a DRYLINE II adult watertrap and a 2.5-meter adult sampling line:
<300 ms@120 ml/min
awRR measurement range 0 to 120 rpm
awRR measurement precision ±2 rpm
Apnea time 10 s, 15 s, 20 s, 25 s, 30 s, 35 s, 40 s
Note: The response time is the sum of the rise time and the delay time.

*: means an extra error should be added in case of gas interference when CO
2
measurements are performed between 0 -
40mmHg.
Inaccuracy specifications are affected by the breath rate and I:E change. The end-tidal gas reading is within specification for
breath rate below 15BPM and I:E ratio smaller than 1:1 relative to the gas readings without breath.

* Accuracy applies for respiration rate up to 80 rpm. For respiration rate above 80 rpm, the accuracy is 4 mmHg or ±12% of
the reading, whichever is greater, for EtCO
2
exceeding 18 mmHg. For respiration rate above 60 rpm, the above accuracy can
be achieved by using the CapnoLine H Set for Infant/Neonatal. In the presence of interfering gases, the above accuracy is
maintained to within 4%.
