end-tidal capnography

end-tidal capnography

[end′tīdəl]
the process of continuously recording the level of carbon dioxide in expired air. The percentage of carbon dioxide at the end of expiration can be estimated and gives a close approximation of the alveolar carbon dioxide concentration. The process, which requires the use of infrared spectroscopy, is used to monitor critically ill patients and in pulmonary function testing. The data are typically recorded automatically on a strip of graph paper on a bedside patient monitor.

Each patient was continuously monitored with electrocardiogram, pulse oximeter, invasive blood pressure, end-tidal capnography, urinary catheter and oesophageal thermometer.
Following intubation there were high airway pressures and ventilation was unsuccessful with no expired carbon dioxide trace on end-tidal capnography.
These include endoscopy, fluoroscopy, bedside videoscopic placement, electrocardiogramguided placement, end-tidal capnography and capnometry (1,4,5.
