† Presented concentration of CO2 and EtCO2 can be false, indicating a high presence of nitrous oxide and Desflurane.

Table 9 shows the CO2 and EtCO2 concentration corrections. Only use agents listed in table 9.
Table 9: CO2 and EtCO2 Concentration Corrections

Agent Concentration Correction of Presented CO2 to Real Concentration
50 – 70% N2O Presented CO2 x 0.75 = Actual CO2

What is LifeSense Vet's recommended sampling tube length for EtCO2 (sampling cannula)?

7 feet (2.1 meters)

What is the longest combination of Nonin extension cable and Nonin oximeter sensor cable specified for use with LifeSense Vet?

The recommended maximum length of extension cable plus sensor cable is 40 feet (12 meters). A nine meter Nonin extension cable may be used with a Nonin three meter sensor.

How often do I need to replace the filter in the moisture trap?

Each filter is single-use and disposable, Replace after each use or if occlusions occur.

What happens to the trending graph after four hours have been displayed?

The LifeSense Vet will continued displaying data in a “looping” fashion, replacing the oldest trend data with new data.

What kind of battery is used in the LifeSense Vet?

Rechargeable lithium ion battery pack.

How many hours of battery life can I expect?

Up to 12 hours when fully charged.

How long does it take to recharge the battery pack?

If the battery pack is completely discharged and the system is turned off, it will take approximately 17 hours. The battery pack charges while the device is plugged in to AC power.

On the touch panel display, each specific parameter is adjusted by using the “up” or “down” arrow on the display bar.

Will the system remember the users' adjusted alarm settings when turned off and turned on again?

No. The LifeSense Vet monitor will reset the alarm limits to factory settings once the monitor is turned off and turned on again.

How long will the audible alarm remain deactivated when the audible alarm pause button is pushed?

Two minutes. Visual alarms will remain.

What is the sampling flow of the LifeSense Vet?

The sampling flow is 100 ml/minute +/- 20ml/minute.

How many minutes of use remain once the "Low Battery" message is displayed?

Approximately 15 minutes.

Can I use LifeSense Vet to monitor EtCO2 on intubated animals?

Yes. Use the ET-tube adapter with sampling tube for monitoring.

Can I place LifeSense Vet in the ventilator circuit line?

Yes. LifeSense Vet can be used on ventilators with the appropriate gas outlet adapter and recommended scavenger tubing. Please note cautions and warnings in Operator’s Manual.

What is the warranty period for LifeSense Vet?

How do I turn off the "Trap full" alarm?

  1. Check the moisture trap and filter and replace if necessary.
  2. Check sampling line for kinks or occlusions and replace as needed.
  3. Press the audible alarm pause button to continue.

If LifeSense Vet was turned on without the SpO2 sensor, should it be restarted in order to use the SpO2 function?

No. Connect the sensor to the unit and it will be ready to display the SpO2 readings.

Does the oximeter require calibration?

No calibration is required.
