LH820 is an external plug and play sidestream CO2 sensor. It does not occupy any host space and connects to host just with one eight-pin plug. LH820 features cutting-edge technology for measurement of instantaneous CO2 concentration, respiration rate, end-tidal CO2 concentration, inspired CO2 concentration, inspiration time and expiration time. It is generally used in patient monitor and anesthetic machine. With a sampling rate low to 50 mL/min, it is ideal for use on adult, pediatric and infant patients; patients ndergoing procedural sedation; and short- term monitoring of intubated patients.
