CO2

The CO2 measurement in M3014A and M3015A complies with EN ISO 21647 (except alarm system;

alarm system complies with IEC 60601-2-49:2001)

Microstream CO2 Humidity Correction Factor

Either BTPS or STPD can be selected as the humidity correction factor for the Microstream CO2

readings. The formula for the correction calculation is:

PBTPS = (PSTPD . 0.94)

M3015A Microstream CO2 Performance Specifications

CO2Range 0 to 98mmHg (0 to 13 kPa), or 13% CO2, whichever is lower
Accuracy Up to 5 minutes during warmup: ±4 mmHg or 12%, whichever is greater
After 5 minutes warmup:
0 to 40 mmHg (0 to 5.3 kPa):±2.2 mmHg (±0.3 kPa)
Above 40 mmHg (5.3 kPa):±(5.5% + (0.08%/mmHg above 40 mmHg)) of
reading
These specifications are valid for 21% O2 and N2 balance, up to 35°C
ambient temperature, up to 60 rpm in adult mode and 100 rpm in neonatal
mode. Outside of these conditions the accuracy reaches at a minimum ±4
mmHg or ±12% of the reading, whichever is greater.
Resolution Numeric: 1.0 mmHg (0.1 kPa)
Wave: 0.1 mmHg (0.01 kPa)
Stability Included in Accuracy specifications
awRR Range 0 to 150 rpm
Accuracy 0 to 40 rpm: ±1 rpm
41 to 70 rpm: ±2 rpm
71 to 100 rpm: ±3 rpm
>100 rpm: ±5% of reading
Warm-up Time 20 minutes for full accuracy specification
Rise Time 190 ms for neonatal mode
(measured with FilterLine H for neonatal)
240 ms for adult mode
(measured with FilterLine H for adult)
Sample Flow Rate 50+15/-7.5 ml/minute
Gas Sampling Delay Time Typical:2.3 seconds
Maximum:3 seconds
Sound Pressure Acoustic noise: < 45 dBA
Total System Response Time The total system response time is the sum of the delay time and the rise time.
