Assumed oxygen consumption (VO 2 ) is increasingly used as a convenient surrogate for measured VO 2 for calculation of cardiac output. This substitution is often based on empirical formulae, previously validated only in relatively young patients. To assess the inaccuracy introduced by extrapolating
An hydraulic orifice formula offering the possibility of quantifying cardiac output in conditlons of mitrai stenosis is tested uslng potentially noninvaslve portlons of catheterization data from patients evaluated for obstructive mitrai valve disease. The equation studied is V = (1/21) R A T2, where
