Background: Capnography has made steady inroads in the ICU
and is increasingly used for all patients who are mechanically
ventilated. There is growing recognition that capnography is rich
in information about lung and circulatory physiology and
provides insight into many diseases and treatments. Aim and
objectives: to evaluate the Role OF Capnography in Weaning in
Mechanically Ventilated COPD Patients. Subjects and
methods: Comparative prospective single group observational
study was conducted in the Critical Care Department – Benha
University Hospitals. The study was conducted upon fifty
mechanically ventilated patients (36 males &14 females)
Results: there was a statistically significant difference between
the studied population regarding correlation coefficient between
PaCO2 and PETCO2 before and after weaning, validity of
PaCO2 and PetCO2 in prediction of successful weaning and
comparison between patients with successful and failed weaning
regarding outcome except in SOFA and APACHE score. There
was no statistically significant difference between the studied
population regarding comparison between patients with
successful and failed weaning regarding vital signs and
comparison between patients with successful and failed weaning
regarding blood gases except in PaCO2 and HCO2. Conclusion:
the present study found that PacO2 and PetCO2 are correlated to
each other before, during and after SBT. Most of the studies that
was found reported that PetCO2 is highly correlated with PaCO2
and that PetCO2 may be a rapid and reliable predictor as arterial
PaCO2 in respiratory distress. |
