Continuous end-tidal carbon dioxide monitoring in pediatric intensive care units

Purpose

End-tidal carbon dioxide (ETCO₂) monitoring has a variety of clinical applications in critically ill pediatric patients. This study was designed to explore the current availability and utilization patterns for continuous ETCO₂ monitoring in pediatric intensive care units.

Methods

A Web-based survey was distributed to directors of all accredited pediatric critical care fellowship programs in the United States.

Results

Sixty-six percent of directors completed this survey. One hundred percent of directors had access to ETCO₂ monitoring for intubated patients and 57% for nonintubated patients. Eighty-three percent of respondents used ETCO₂ monitoring “always” or “often” for endotracheal tube confirmation. Fifty percent of respondents used ETCO₂ monitoring “always” or “often” for cardiopulmonary resuscitation, 38% for moderate sedation, and 5% for acid-base disturbances. All respondents who used ETCO₂ monitoring felt that it was easy to use. The most common reason for not using ETCO₂ monitoring was lack of availability (75%).

Conclusions

End-tidal carbon dioxide monitoring is widely available and used for intubated patients. However, it could be applied more frequently in other clinical situations in pediatric intensive care units.
