What does a presence of waveform on the capnography screen and petco2 level of 8 means?

The presence of a waveform on the capnography screen indicates that there is effective ventilation and that carbon dioxide is being expelled from the lungs. However, a PETCO2 level of 8 mmHg is significantly lower than the normal range (typically 35-45 mmHg) and suggests severe hypoventilation or respiratory distress. This combination of a waveform with such a low PETCO2 level may indicate a patient who is breathing inadequately, potentially requiring urgent medical intervention.
