36 hours following admission to the hospital, despite supplemental oxygenation the patient’s respiratory status continued to worsen. An ABG shows pH 7.3, PO2 55 mmHg, PCO2 38 mmHg. His chest x-ray is shown below. The decision for intubation and mechanical ventilation is made. What is the most important consideration when placing this patient on the ventilator?

High levels of PEEP (Positive End Expiratory Pressure)

A 55 year old Bahamian male with a long history of smoking presents to the Emergency Department in severe respiratory distress. An aterial blood gas shows a PO2 of 50 mm Hg and a PCO2 of 80 mm Hg. Your treatment of the above patient should concentrate on

Adult respiratory distress syndrome

Idiopathic interstitial pulmonary fibrosis

Adult respiratory distress syndrome

Following a vehicular accident with blood loss leading to prolonged, severe hypotension, a 30-year-old man is intubated and placed on a mechanical ventilator. He has progressively decreasing oxygen saturations despite increasing PEEP and FiO2 of 100%. He remains afebrile and dies 3 days later. The microscopic appearance of the lungs is shown. Which of the following pulmonary diseases most likely complicated his course?

Adult respiratory distress syndrome

The chest x-ray of a 56 year-old female with pancreatitis and respiratory failure shows patchy, wide spread infiltrates without evidence of heart enlargement or congestion. The decision is made to intubate and mechanically ventilate this patient. The most important ventilator setting to consider in this patient is:

High levels of positive end expiratory pressure (PEEP)

Continuous positive airway pressure (CPAP)
