Dr. Kelso: All right, sports fans, we have a guest today at rounds, so let's try and be sharp. Why don't we begin with, uh, I don't know, Dr. Reid. What is the nutritional cause of high output cardiac failure?
Elliot: Wet beriberi from thiamine deficiency.
Dr. Kelso: Yes, it is. Next question. Why don't we try... Dr. Reid.
Elliot: Um, I already went, sir.
Dr. Kelso: Oh, are you done for the day?
Elliot: No.
Dr. Kelso: What is the mechanism of Cheyne-Stokes respiration in systolic dysfunction?
J.D.: [v.o.] What? Nobody knows that.
Elliot: Prolongation of circulation time from lung to brain causing diminished sensitivity of the respiratory center to arterial partial pressure of carbon dioxide?
Dr. Kelso: Yes.
