- severe renal
CAS better for pts with:
- CHF < 30%
- CAD w/unstable angina
- abnormal stress test or MI < 1 month
- Valve disease
- Severe obesity
- Contralateral RLN injury
Aortic aneurysm least likely to cause aortic insufficiency

FGF coupled ventilators equation
3 L/min = 3000 ml/min.
I:E ratio 1:3 → 3000 x 1/3 = 1000
1000ml/10 RR = 100 ml
Vt = 450ml, so 100 ml + 450 ml = 550ml total volume to pt
TURP fluids
- 10-30 ml/min retained
- EBL 2-5 ml/min
