The causative agent of lower respiratory tract infection cannot always be determined even with invasive techniques. In most clinical situations an empirical choice of antibiotics is indicated, if only for early institution of therapy. Next to the often misleading clinical picture, consideration of the epidemiological setting and specific risk of underlying diseases is of value in selecting empirical therapy.
即使采用侵入性技术，也并非总能确定下呼吸道感染的病原体。在大多数临床情况下，即使只是为了尽早开始治疗，也需要凭经验选择抗生素。除了常常具有误导性的临床表现外，在选择经验性治疗时，考虑流行病学背景和潜在疾病的特定风险也很有价值。
