LifeSense VET Capnograph and Pulse Oximeter

Availability: In Stock

The LifeSense Vet is a multiparameter monitor for veterinary use that measures and displays end-tidal carbon dioxide (EtCO2) and fractional inspired CO2 (FiCO2) values, respiration, functional oxygen saturation of arterial hemoglobin (SpO2), and pulse rate of intubated animals. The widescreen display also serves as a user-friendly touch panel where all settings and adjustments are made.

† 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
30 – 50% N2O Presented CO2 x 0.85 = Actual CO2
0 – 30% N2O No correction
0 – 5% Isoflurane No correction
0 – 8% Sevoflurane No correction
