RespSense II

WIDESCREEN Capnograph

The RespSense II capnograph with widescreen touch-panel display offers Nonin sidestream EtCO2 technology for intubated and non-intubated patients in a wide range of clinical settings. Portable, accurate, and cost-effective, RespSense II is suitable for use with patients in hospitals, sleep labs, and homecare.

Capnography Specifications

Respiration Range: 0 to 99 respirations/minute
Respiration Accuracy1, 2:
3 to 50 respirations/min ± 2
51 to 60 respirations/min ± 3

Test method summary: To determine the rated respiration rate, calibrated CO2 gas tanks are used as the respiration rate is changed from 3 to 60 BrPM.

EtCO2/CO2 Range: 0 to 99 mmHg (0 to 13.2 kPa)
EtCO2/CO2 Accuracy:
±0.2 kPa / ±2 mmHg, +8% of reading3
525 – 795 mmHg (700 – 1060 hPA)
(EtCO2/CO2 reading reaches its steady state accuracy within 10 minutes after power up. From maximum storage temperature, monitor reaches steady state accuracy 19 minutes after power up.)

Calculated Update Frequency: Once every breath (“NO BREATH” alarm after 30 seconds)
Sampling Rate: 4 Hz (4 times per second)
Total System Response Time: <7 seconds (includes delay time and rise time)
Drift of Measurement: Within CO2 accuracy specifications for 6 hours of continuous monitoring
Measurement: Automatic barometric pressure compensation and CO2 temperature compensation

1 There is no known adverse effect on performance due to cyclical pressure up to 10 kPa.
2 There is no degradation in EtCO2 measurement accuracy as a function of BrPM and inspiratory/expiratory (I/E) time ratio.
3 Presented concentration of CO2 and EtCO2 can be false, indicating a high presence of nitrous oxide and other interfering gases.

The table below shows the CO2 and EtCO2 concentration corrections. Only use agents listed in the table below.

Agent ConcentrationCorrection of Presented CO2 to Real Concentration
50 – 70% N2OPresented CO2 x 0.75 = Actual CO2
30 – 50% N2OPresented CO2 x 0.85 = Actual CO2
0 – 30% N2ONo correction
