What ETCO2 Actually Reflects
- End tidal CO2 (ETCO2) measures CO2 at end-exhalation and reflects alveolar CO2 non-invasively.
- ETCO2 reflects ventilation but is also strongly affected by cardiac output and the sampling circuit.
Choose Capnography For Full Detail
- Use quantitative capnometry for numbers and capnography for waveform morphology to gain diagnostic detail.
- Prefer capnography when you need to interpret trends, diagnose obstruction, or assess treatment response.
Protect And Configure The Sampling Circuit
- Protect CO2 sensors from fluids and ensure proper circuit order: airway → catheter mount → HME → ETCO2 sensor.
- Check for contamination or misplaced filters if CO2 readings are unexpectedly absent or low.
