Which is an indication for tracheostomy tube replacement?

• A. Hypoxia
• B. Hypotension
• C. Tachycardia
• D. Hypoglycemia

Answer: (A)

Airway patency and reliable oxygen delivery are the focus. When a tracheostomy tube isn’t providing adequate ventilation, hypoxia occurs, signaling that the tube may be obstructed, displaced, or otherwise failing to maintain the airway. Replacing the tube promptly aims to restore a secure airway and oxygenation. The other signs reflect circulation or metabolic problems rather than a direct airway device issue; hypotension and tachycardia can accompany many conditions, and hypoglycemia is a metabolic problem, not a direct indication to replace the tracheostomy tube.
