Ex vivo bovine trachea is used as a tissue-simulating material in medical simulation training where tracheal anatomy, ring palpation, and needle puncture practice are required. Documented application: bronchoscopy-guided percutaneous dilatational tracheostomy (BG-PDT) training, in which a 20 cm segment (from below the larynx to the carina) is mounted on a PVC half-pipe cradle to support up to 6 training iterations per specimen.[1]

At a Glance

Overview

[edit source]

Ex vivo bovine trachea is the windpipe (trachea) harvested from cattle, used fresh or thawed as a biological tissue-simulating material. Like all mammalian tracheas it is a tube of firm, incomplete C-shaped cartilage rings joined by connective membrane and lined with mucosa, giving natural ring landmarks for palpation and tissue resistance to needle puncture. It is an abattoir or butcher by-product, kept refrigerated or frozen until use and discarded after a limited number of uses. In the documented application a 20 cm segment (from below the larynx to the carina) supports about 6 training iterations per specimen at roughly US$1.7 per use (Kattan et al. 2019).
