整个句子的状语还是？谢谢

Bronchoscopic information serves as a crucial step in procedural and operational planning for both interventional pulmonologists and thoracic surgeons. However, flexible bronchoscopy may be difficult and can potentially lead to accelerated respiratory failure in patients with severe tracheal stenosis and airway narrowing. First, the size of the bronchoscope may occlude an already narrowed airway, thus further impeding oxygenation and ventilation. One method to mitigate this risk is by using an ultrathin bronchoscope which has a diameter as small as 3.1 mm. Second, sedation used during bronchoscopy can cause relaxation of the respiratory muscles, which may worsen airway narrowing and lead to respiratory failure.

支气管镜检查获得的信息对介入肺科医师和胸外科医师操作和手术计划至关重要。但在严重气管/气道狭窄的患者中，柔性支气管镜检查可能困难，并且可能加速呼吸功能衰竭。首先，无论多大的支气管镜都可能堵塞已狭窄的气道，从而进一步阻碍氧合和通气。一种降低该风险的方法是使用直径小至3.1mm的超细支气管镜。其次，支气管镜检查期间使用的镇静剂可导致呼吸肌松弛，这可能会加重气道狭窄并导致呼吸衰竭
