capnography
Pronunciation: cap-NOG-rah-fee
Continuous monitoring of exhaled carbon dioxide concentrations, providing real-time assessment of ventilation and circulation in critically ill children.
Full Definition
Capnography is a non-invasive monitoring technique that measures and displays the concentration of carbon dioxide (CO2) in exhaled breath over time. In pediatric critical care, it serves as an essential tool for monitoring ventilation adequacy, detecting airway obstruction, and assessing circulation status. The capnogram waveform provides immediate feedback on respiratory mechanics and can alert clinicians to complications such as airway displacement, circuit disconnection, or cardiovascular compromise. It is particularly valuable in sedated or paralyzed pediatric patients where clinical assessment alone may be insufficient.
In Context
- "Continuous capnography revealed an obstructive pattern consistent with bronchospasm." — Clinical assessment note
- "The sudden loss of capnography waveform prompted immediate assessment for endotracheal tube displacement." — Critical incident report
