Sophisticated CO2 measurement
All Hamilton Medical ventilators provide volumetric capnography, either standard or as an optional feature. The CO2 measurement is performed using a CAPNOSTAT® 5 mainstream CO2 sensor at the patient‘s airway opening.
The CAPNOSTAT 5 sensor provides technologically advanced measurements of end-tidal carbon dioxide (PetCO2), respiratory rate, in addition to a clear, accurate capnogram at all respiratory rates up to 150 breaths per minute.
Volumetric capnogram on the display
The volumetric capnogram window on the display shows:
1) Current volumetric capnogram curve
2) Volumetric capnogram reference curve
3) Reference curve button with time and date of reference loop
4) Most relevant CO2 values, breath by breath
72-hour trend function
To allow a more comprehensive analysis of the patient condition, a 72-hour trend (or 96-hour with HAMILTON-S1/G5) is available for:
PetCO2, V‘CO2, FetCO2, VeCO2, ViCO2, VTE/Vtalv, VDaw, VD/Vt, Slope CO2
Volumetric capnography in monitoring
To make your life easier, Hamilton Medical ventilators offer an overview of all relevant CO2-related values in the Monitoring CO2 window.
