Transcutaneous CO2 (TC-CO2) monitors function by measuring the CO2 which diffuses out the skin. Modern TC-CO2 monitors are a highly accurate, non-invasive method for estimating paCO2.[1]
Important Points
- Initial reading requires approximately five minutes to establish.
- TC-CO2 measures paCO2 trends; it DOES NOT measure instantaneous levels. Therefore, TC-CO2 is NOT an acceptable substitute for ET-CO2 in these situations:
- Confirmation of ET-tube placement.
- Respiratory monitoring during sedation.
- Any situation where apnea is a concern.
Device
YKDRH has acquired the Sentec Digital Monitoring System.
The Sentec devices provides monitoring of:
- Instantaneous oximetry
- Instantaneous heart rate
- Trending of paCO2
Resources
- Instruction Manual
- Instructional Video
