EtCO2

End tidal CO2 monitoring is vertegenwoordigd als een nummer en een grafiek op een monitor. Het nummer is wel capnometry, die is de partiële CO2 gedetecteerd eind uitademing. De golfvorm is wel capnograph en toont hoeveel CO2 is aanwezig op elke fase van de luchtwegen cyclus.

What does it mean when EtCO2 is low?

ETCO2 measures the effectiveness of ventilation, as long as the patientʼs blood flow (cardiac output) is normal. If the cardiac output falls, less CO2 is returned to the lungs and if the breathing doesnʼt change, more CO2 will be removed than what is brought to the lungs and the ETCO2 will fall.


How to use etco2 monitoring

Sidestream monitors rely on a separate monitor connected to the patient's airway by a tube. With mainstream capnography, the airway adapter is placed directly in the breathing circuit in between the ventilator “Y” and the elbow adapter. A mainstream sensor is then attached to the adapter. As the patient exhales, the CO2-rich gas passes through the airway adapter, where it is measured.
