TOF: If SVR decreases, it becomes easier for blood to flow...?

into the aorta. Qs improves. More blood is shunted to the right --> left across the VSD. Qp decreases. Oxygenation worsens. Tet spell!

How do we resolve a Tet spell?

Increase SVR: knees to chest (inc. SVR), vasoconstrictors (vaso/phenyl), & sedation

TOF: Are they ductal dependent? If so, why?

Depends: Pulm atresia/ severe pulm stenosis=RVOTO, and needs PDA

In TOF: blood exiting the RV must choose between (2):

1. Pulmonary circulation (thru narrowed RVOT) or 2. Systemic circulation (across VSD into the overriding aorta)

TOF: If SVR increases (squatting, knees-to-chest, pain-induced vasoconstriction), it becomes more difficult for blood to

enter the aorta, Qs decreases while Qp increases. PBF improves.

TOF: what happens if the atrial septum is intact?

No RA -> LA decompression, no back-up mixing route. Qp/Qs becomes dependant on RVOTO & SVR. Sm. changes in preload, afterload, or PVR = desat + cardiac output
