Question

Quizplus · Accepted Answer

This patient is suffering from an increased WOB,as evidenced by the use of accessory muscles and elevated respiratory rate.Adding pressure support will decrease the patient's WOB by eliminating the airway resistance caused by the ET tube.Returning the patient to full ventilatory support before trying pressure support may add time to the patient's length of stay on the ventilator.Increasing the CPAP is not appropriate,because there is no evidence of hypoxemia.Deflating the cuff would negate the CPAP and also increase the risk of ventilator-associated pneumonia.
