A 59-yeаr-оld mаn with а histоry оf heart failure is suddenly awakened in the middle of the night with the feeling that he is smothering. When you arrive at the scene, you find him lying in bed with his head propped up by three pillows. He is conscious and alert but is experiencing obvious respiratory distress. His skin is pale and diaphoretic.Recalling how your patient presented (respiratory distress and hypoxemia), the primary origin of his problem was failure of:
