Part 3

The patient underwent broncho-alveolar lavage and pneumonia was ruled out. The patient was treated with oxygen and attempts were made to extubate the patient over the next several days. However with each attempt the patient could not maintain his O2 saturations.

	Additional workup at that time revealed marked pulmonary bullous disease on CT scan.
	A Chest view composite from the CT scan also showed cardiac enlargement:

1. Look at the patient’s O2 trends to get an idea of his lung function and how treatment with intubation helped.

2. What effect does oxygenation have on the heart?
