Introduction[edit | edit source]

Weaning a patient from a Ventilator occurs when the condition of the patient improves and a decision is made to remove them from the ventilator through a trial of spontaneous breathing through the endotracheal tube and eventually extubation (removal of the tube).

Procedure[edit | edit source]

The procedure is as follows:

  • Explanation of the procedure to the patient, assuring them that it is only for a trial period.
  • The ventilator support is gradually reduced (e.g. reducing pressure during pressure support).
  • Choose a better posture for the patient (e.g. sitting upright or half-sitting).
  • The airway is suctioned.
  • The patient is disconnected from the ventilator and given oxygen or mechanical assistance (CPAP).
  • The patient is encouraged to breathe spontaneously.
  • Look for signs of laboured breathing, anxiety or an increase in PaCO2.
  • Extubation should occur as soon as possible because breathing through an endotracheal tube increases the Work of breathing.
  • Encourage the patient to cough after being extubated.

Patients may be extubated when they are alert, show a stable breathing pattern and control their airway. Difficulties in weaning patients from a ventilator can occur because of:

  • Inspiratory muscle atrophy
  • Fatigue
  • Paralysis of the diaphragm
  • A fear of suffocating
