[You would recommend placement of an artificial tracheal airway to:] enable negative pressure ventilation decrease auto-PEEP protect against pulmonary aspiration increase anatomic deadspace None . [A patient with emphysema receiving volume control A/C ventilation develops signs of air trapping (auto-PEEP). The doctor does not want to switch to SIMV. Which of the following actions would help resolve this problem?] decrease the length of time available for exhalation increase the preset frequency of breathing by 30% increase the length of time available for exhalation increase the inspiratory time by decreasing the flow None . [Assessment of an area of consolidation in the lung would most likely reveal:] Dull percussion Tracheal deviation Decreased fremitus Late inspiratory crackles None .
