Measure RR with respiratory simulator and I/E ratio as 1:1 according
to EN ISO 80601-2-55 fig 201.101
The EtCO measurement accuracy is affected by the respiration rate.

For Kingst CO module:
2
Sidestream: Rise time < 250 ms (t 10%-90%), total system
⚫
response time < 4 s when use a 2.4 m sampling line.
Mainstream: Rise time is approximately 70 ms (t 10%-90%),
⚫
total system response time < 1 s.
Short-term: The module works for more than 4 hours, and
⚫
the maximum drift does not exceed 0.8 mmHg.
Long-term: The module works for more than 120 hours and
⚫
still meets the specified performance standards.
The time of reaching the specified working performance after the
CO module is switched on:
2
Mainstream: Parameters can be displayed within 15 s, and
⚫
the ambient temperature is 25°C, and it takes 2 minutes to
reach the specified working performance standard.
Sidestream: Parameters can be displayed within 20 s, and
⚫
the ambient temperature is 25°C, and it takes 2 minutes to
reach the specified working performance standard.
When the sampling gas temperature is 37°C, the indoor temperature
is 23°C, and the sampling relative humidity is 100%, the maximum
time interval for the operator to intervene in the water and gas
treatment system is 120 hours.
Sidestream: 2 rpm-150 rpm
