BackgroundPulmonary exacerbations (PEx) lead to substantial morbidity in cystic fibrosis (CF), and guidelines recommend chronic medication including dornase alfa and inhaled tobramycin. However PEx risk and medication use vary across patients.
ObjectiveTo develop a PEx risk score among CF patients not receiving guideline‐recommended chronic respiratory medications.
MethodsA cohort of patients with...
Research on the neutral gas diffusion simulation, improved the Gaussian plume model which simulate under continuous leakage status. Add the terrain factor to the model; calculate with digital elevation model (DEM) in order to verify the idea. Using geographic information system (GIS) control technology developed chemical gas leakage simulate system, take the ammonia diffusion for instance, dynamic...
