WIDESCREEN™ Capnograph and Pulse Oximeter
The LifeSense II widescreen capnograph and pulse oximeter offers proven PureSAT® SpO2 and sidestream EtCO2 technologies for both intubated and non-intubated patients in a wide range of clinical settings. Easy to use, accurate, and cost-effective, LifeSense II is suitable for SpO2 and EtCO2 monitoring of patients in hospitals, sleep labs, and homecare.
Pulse Oximeter Specifications
Oxygen Saturation Display Range: 0 to 100 % SpO2
Pulse Rate Display Range: 18 to 321 beats per minute (BPM)
Infrared: 660 nanometers @ 0.8 mW max. average
Red: 910 nanometers @ 1.2 mW max. average
Accuracy – Sensors: Declared accuracy data for compatible sensors can be found in Nonin’s Sensor Accuracy document.
*This information is especially useful for clinicians performing photodynamic therapy.
Respiration Range: 0 to 99 respirations/minute
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 Accuracy1, 2:
±0.2 kPa / ±2 mmHg, +8% of reading3
540 – 795 mmHg (720 – 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 Concentration||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||No correction|
