LifeSense II

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)
Measurement Wavelengths*:

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.

Capnography Specifications

Respiration Range: 0 to 99 respirations/minute
Respiration Accuracy:
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^{1, 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
