Transtracheal Oxygen Catheter (TTO)

Oxygen therapy

Oxygen therapy improves survial for patients with chronic lung conditions, including COPD. Additionally, oxygen can reduce symptoms of breathlessness and increase exercise tolerance. Traditional oxygen is delivered by nasal cannula; however, transtracheal oxygen bypasses the upper airways and is delivered through a catheter in the trachea.

Why is it used?

  • Using a transtracheal approach to oxygen delivery can reduce the amount of oxygen flow needed at rest and with exercise
  • It can reduce the symptoms of shortness of breath and improve patient mobility

What Makes Transtracheal Oxygen Different?

  • Unlike other oxygen therapies, it is delivered directly into the trachea via a small catheter
  • This type of delivery can improve oxygen compliance and may be more comfortable than traditional nasal delivery

Benefits of Transtracheal Oxygen Delivery

  • TTO delivery bypasses the “dead space” in the upper airways and mouth, allowing oxygen to pass directly into the trachea
  • This reduces the overall oxygen needed during rest and with exercise

Appointments & Referrals

NOTE: All referred patients will still have the option of continuing treatment with their primary care physicians after the procedure.
