The following modes of ventilation may be used for wearing off patients from mechanical ventilation except:
|A||Controlled mechanical ventilation (CMV)|
|B||Synchronized intermittent mandatory ventilation (SIMV)|
|C||Pressure support ventilation (PSV)|
|D||Assist-control ventilation (ACV)|
Controlled mechanical ventilation (CMV)
Controlled mode ventilation (CMV) is utilized for patients who don't have any spontaneous effort (meaning thereby that the patient cannot be weaned). In rest of all other modes there is patient's own effort.
