When patients are on the ventilators it is common to give them a sedation to keep them comforable and to give them a relief from the pain. In most instances,the sedation is not required and in a few cases,the sedation might even turn out to be harmful. Likewise, if a patient will be taking off the ventilator should be in co-operation with a pulmonologist or respiratory specialist who adjusts the setting of the ventilator or administers other treatments such as medication.
