Pulse-contour stroke volume estimates warrant caution amid variable hemodynamics; leaves open reliability across multi-perturbation conditions.
Do pulse-contour methods accurately estimate stroke volume from central aortic pressure compared to measured stroke volume?
Pulse-contour methods for estimating stroke volume from central aortic pressure perform inadequately under varying hemodynamic conditions, limiting their clinical utility.
Starmer et al. (1973) studied this question.
