When suctioning a tracheostomy, which action best helps prevent hypoxia?

Question

Accepted Answer

B. Hyperoxygenate before and between suction passes — Suctioning removes oxygen along with secretions. Pre-oxygenation (and limiting each pass to ~10–15 seconds) reduces hypoxia. Routine saline instillation is not recommended unless specifically indicated by protocol.

Answer

C. Instill sterile saline routinely before suctioning
