Mainstream CO2 Sensor LH900

Product Introduction
ETCO2 module is the ideal capnography solution. It is plug-in and play. The sensor features advanced technology for measuring instaneous CO2 concentration, respiration rate, end-tidal CO2 concentration, inspired CO2 concentration . It resist the vapour better with patented technology, make the measured result more accurate.

Application Field

1.Monitoring the patient's respiratory status

2.Assists in determining when to intubate or extubate

3.Verification of ET tube placement

4.Alerts if accidental extubation occurs

5.Ventilator disconnect detection

6.Verification of ventilation during transport
