The diagnostic and therapeutic utility of flexible fibreoptic bronchoscopy (FFB), coupled with its minimal morbidity and mortality, have led to its increasing use in the care of the critically ill patients. FFB allows direct inspection of the upper and lower airway, and facilitates the diagnosis and management of a variety of pulmonary disorders. Patients in the intensive care unit are predisposed to a higher risk of complications as they are usually mechanically ventilated with positive end-expiratory pressure, and have other medical conditions such as coagulopathies, thrombocytopenia, uraemia, cardiac disease, hypoxaemia, pulmonary hypertension, and immunosuppression. An awareness of the higher risks associated with certain clinical conditions, and an understanding of the pathophysiological consequences associated with FFB should alert the bronchoscopists to take the necessary precautions to prevent and deal with these problems.
可弯曲纤维支气管镜（FFB）的诊断和治疗效用，再加上其极低的发病率和死亡率，使得它在重症患者护理中的应用越来越广泛。FFB可直接检查上、下气道，并有助于诊断和管理各种肺部疾病。重症监护病房的患者更容易出现并发症，因为他们通常接受呼气末正压机械通气，并且患有其他疾病，如凝血功能障碍、血小板减少症、尿毒症、心脏病、低氧血症、肺动脉高压和免疫抑制。认识到某些临床状况相关的较高风险，以及了解与FFB相关的病理生理后果，应提醒支气管镜检查人员采取必要的预防措施来预防和处理这些问题。
