SHUNT CALCULATION:LEFT RIGHT shunt

*If shunt is at ventricular level the mean R.A. SO2 will be subtracted from Arterial SO2

*If shunt is at arterial level, then Mixed Venous SO2 is taken for calculation.

P.B.F. (L/min) = VO2 cc/min S.B.F. (L/min) = - O2

Art. O2 – PA O2 vol. % Art O2 - Venous O2 = x10 = 66 x 1/10 = =

= L/min = L/min.

S.B.F. (L/min) = VO2 cc/min = x1/10 Art. O2 – PA O2 vol. %

Right to left shunt = S.B.F. minus total P.B.F. = L/min.

BIDIRECTIONAL SHUNT

Effective P.B.F. (L/min) = VO2 = x10 PV O2 – mixed venous =

= L/min

(with Bidirectional shunt formula)Right Left = S.B.F. minus Eff. P.B.F. = L/min Left Right = Total P.B.F minus Eff. P.B.F. = L/min Resistance Conversion Factors: 1332 (coverts mm.Hg to dynes/cm2) : 0.06 (converts L/min to cc/sec.) : 1332 x 0.06 = 80.

T.P.V.R. = mean P.A. x 80 = dynes/sec/cm-5

Pulm. C.O.P.V.R. = mean P.A. – mean P.C. x 80 = dynes/sec/cm-5
