What is the normal range of End Tidal CO2 output measured in mmHg?

The normal range of End Tidal CO2 (EtCO2) output, typically measured in mmHg, is generally accepted to be between 35 to 45 mmHg. This measurement is significant as it indicates the adequacy of ventilation and the efficiency of gas exchange in the lungs.

An EtCO2 within this range suggests that the body's metabolic processes are functioning properly, indicating that carbon dioxide is being produced and eliminated at a balanced rate. Values lower than 35 mmHg may indicate hyperventilation or a possible respiratory disturbance, while values above 45 mmHg may suggest hypoventilation or an accumulation of carbon dioxide, which could signal respiratory failure or other critical conditions.

Understanding this range helps paramedics and healthcare providers in assessing a patient's respiratory status quickly and effectively, guiding timely interventions if necessary.
