Lead Sponsor:
The First Affiliated Hospital of Guangzhou Medical University
Conditions:
COPD
Eligibility:
All Genders
40-85 years
Brief Summary
Sidestream end-tidal CO2 has been found to be closely correlated to PaCO2 especially when people have the stable hemodynamics and normal lung function. PETCO2 can basically reflect the level of PaCO2,...
Detailed Description
Non-invasive positive pressure ventilation(NPPV) can significantly improve gas exchange and relieve respiratory muscle fatigue for COPD,and arterial blood gas is the gold standard to evaluate ventilat...
