During a pneumogram, which parameter is tracked along with respiratory movement, heart rate, and SpO2?

• A. Blood pressure
• B. End-tidal CO2
• C. Nasal air flow
• D. Respiratory rate

Answer: (C)

A pneumogram tracks breathing effort and actual airflow to judge ventilation adequacy. The key extra parameter is nasal airflow, because it provides a direct measure of air moving through the nose, revealing whether there is real airflow matching the chest/abdomen movement. This helps detect issues like airway obstruction or a mismatch between effort and ventilation. End-tidal CO2 is a capnography measure and isn't part of the classic pneumogram tracing; blood pressure isn’t a respiratory tracing parameter, and respiratory rate is usually derived from the breathing movement itself, not an independent pneumogram signal.
