Module 2: Breathing with

Tracheostomy

With a tracheostomy, respiratory support is provided through the connection of air from ventilator to a tracheomstomy cannula. A tracheostomy cannula is a plastic tube which passes through a hole in the throat and enters into the trachea. Ventilation provided by this techinique is called invasive mechanical ventilation therapy, as opposed to non-invasive therapy, e.g., mask therapy.

Indications


Why do some people need a tracheostomy (invasive treatment) and when should it be performed?

  1. Some types of respiratory failure increase the need for respiratory support. When ventilatory support is critical, mask therapy could be less safe ande even more cumbersome than invasive treatment. Choices depend on individual preferences. To some patients 24/7 nonivasive treatment is preferable, but others may prefer a tracheostomy even when ventilatory support is required for more than 16 hours during a 24-hour period. Advantages and disadvantages need to be discussed with each patient.


The upper airway muscles of some patientse may be weakened, causing problems with swallowing and keeping the airways open or free/ protected from aspiration. Mucus and residual food could enter into the trachea and lungs with the subsequent risk of breathing problems and pneumonia. Weakened upper airway muscles can also lead to airway collapse, especially when sleeping. If these problems cannot be solved in any other way and mask therapy is difficult, a tracheostomy could be a potential solution.

Some experience an increased problem with mucus in the airways, This could be caused by reduced ability to cough effectively, problems with swallowing or more proneness to mucus production due to a lung disease. If these problems cannot be solved in any other way and mask therapy is difficult, a tracheostomy could be a potential solution.

If a user has persistent hypoventilation despite optimal mask therapy, a tracheostomy could provide improved ventilation.


Advantages of a tracheostomy

  • Can be life-saving.
  • Can give a better quality of life than mask therapy in some cases.
  • No face mask is required.
  • Less problems with leakage.
  • Direct entry of air to the trachea and lungs:
    • Mucus can be removed more easily.
    • Safe and easy to ventilate patient.

Disadvantages of a tracheostomy

  • Increased risk of infection, haemorrhaging and scar tissue.
  • Natural humidification, heating and filtering of air is lost.
  • Invasive surgery is required.
  • One has to live with a ‘hole in the throat’.
  • The ability to swallow and speak may deteriorate.
  • The ability to taste and smell can change.
  • Caregivers require more training.
  • More technical equipment is needed.
