answer
Tube placed between nose and upper airway. Used to suction secretions in patients with poor cough.
question
What is an Oropharyngeal Tube?
answer
Tube placed between mouth and airway. Prevents obstruction of airway by moving tongue anteriorly and facilitates suctioning.
question
What are the two types of airways used for Mechanical Ventilation?
answer
Endotracheal Tubes (ETT) and Tracheotomy
question
What is an Endotracheal Tube?
answer
Tube inserted through mouth, into trachea, when pt is in respiratory failure. Allows air to pass in and out.
question

answer
Pt wears collar around neck to secure tracheotomy tube.
question
What are the advantages of artificial airways?
answer
Prevent airway obstruction Protect airway from aspiration Facilitate suctioning Provide closed system for mechanical ventilation.
question
What are the disadvantages of artificial airways?
answer
Cough is less effective Reduced ciliary motion (so suction instead) Interferes with communication and nutrition Bypasses respiratory defense mechanisms Tracheal stenosis
question
Is ventilation a contraindication to mobility and therapeutic intervention?
answer
NO!
question
What should you do if a tracheal tube becomes unattached?
answer
Perform manual ventilation with an ambu bag and call for help.
question
What are some important things to remember to do before, during, and after treatment of a pt with an artificial airway?
answer
They CAN participate in therapeutic interventions. Prior to treatment: ensure airway is stable, listen to breath sounds, note position of tube. During: Airway still stable? Listen to breath sounds, position of tube. After: Listen to breath sounds, position of tube.
