(Ans- Extubate After assisting with bronchoalveolar lavage and lung biopsy on a mechanically ventilated patient, the respiratory therapist notes the activation of a high pressure alarm. Peak inspiratory pressure has increased from 32 cm H2O before the procedure to 45 cm H2O after the procedure. Possible causes for the increased pressure include 1. bronchospasm. 2. pneumothorax. 3. pulmonary hemorrhage.

The patient's heart rate is 45/min, respiratory rate is 30/min, and blood pressure is 60/40 mm Hg. What action should the therapist recommend first? (Ans- Needle aspirate into the 2nd left intercostal space All of the following strategies are likely to decrease the likelihood of damage to the tracheal mucosa EXCEPT: -maintaining cuff pressures between 20 and 25 mm Hg. - using the minimal leak technique for inflation. - using a low-residual-volume, low-compliance cuff. - monitoring intracuff pressures.
