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.
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)
±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.
||Correction of Presented CO2 to Real Concentration
|50 – 70% N2O
||Presented CO2 x 0.75 = Actual CO2
|30 – 50% N2O
||Presented CO2 x 0.85 = Actual CO2
|0 – 30% N2O
