Evaluation of a new nasal cannula based capnometry device for continuous monitoring of carbon dioxide during different breathing patterns in patients extubated after abdominal surgery: A prospective observational study.
Phase 1
- Conditions
- abdominal surgical patients
- Registration Number
- JPRN-UMIN000014062
- Lead Sponsor
- Yokohama City University Hospital Department Anesthesiology
- Brief Summary
EtCO2 measured by nasal cannula capnometry type was significantly correlated with PaCO2 by blood gas analysis. However, dissociation was widely variated. Therefore, it is difficult to predict absolute PaCO2 value with using EtCO2 value.

- Primary Outcome Measures
Name Time Method We compare EtCO2 measured by capnometry by using an nasal canulae with a carbon dioxide sampling port and partial pressure of carbon dioxide (PaCO2)
