The ventilator discontinuation process is an essential component of overall ventilator management.
Undue delay leads to excess stay, iatrogenic lung injury, unnecessary sedation, and even higher
mortality. On the other hand, premature withdrawal can lead to muscle fatigue, dangerous gas
exchange impairment, loss of airway protection, and also a higher mortality. Continued ventilator
dependence can be a result of persistent illness or can be a result of poor management.
