The desulfurizers (cyclobutyl sulfone and diisopropanolamine) have poisonousness. If the sweetening solution foamed seriously that can't be used, sweetening solution's discharge will affect environment.

脱硫溶液严重发泡后将不能再使用，且脱硫溶剂环丁砜和二异丙醇胺都具有毒性，脱硫溶液的排放将会对环境安全造成严重地影响。

Among pathogens , the most common pathogens associated with VAP were Pseudomonas aeruginosa ( 3013 %), Acinetobacter baumanii (1115 %), Klebsiella pneumoniae ( 1017 %), Escherichia coli ( 716 %) and S taphylococcus aureus ( 618 %). Their multiple drug2resistance to antibiotics was serious. Drug sensitivity tests indicated that the GNB had lower drug2 resistance to such antibiotics as imipenem , amikacin , piperacillin/ tazobactam , ceftazidime , cefepime , cefoperazone/sulbactam , ciprofloxacin and ticarcillin/ clavulanate. Polymicrobial pathogens were more isolated in late2onset VAP than in early2onset VAP.
