SLIDE RULE FOR HEMODYNAMIC MANAGEMENT OF ADULTS

is a simple tool for rapid hemodynamic management of adult patients. It identifies the causes (hyper- or hypovolemia, hyper- or hypoinotropy, vasoconstriction or vasodilation, hyper- or hypochronotropy) of abnormal hemodynamic state (hyper- or hypotension and/or hyper- or hypodynamic state). Therapeutic correction of the causes produces normovolemia, normoinotropy, normovasoactivity and normochronotropy, which, in return, result in normohemodynamic state (normotension & normodynamic state).

Front Side (shown):

The upper function determines the value of hemodynamically-significant Mean Arterial Pressure (MAP) from the measured values of Systolic and Diastolic pressure (the range of normotension is graphically identified).

The lower function determines the combined percentage deviation in (volume +/- inotropy) from normo(volemia +/- inotropy) [the range of normo(volemia +/- inotropy) is graphically identified]. The inputs for this determination are the MAP and SI values.

Back side:

The upper function determines the percentage deviation in vasoactivity from normovasoactivity (expressed as % of vasoconstriction or vasodilatation) (the range of normovasoactivity graphically identified). The inputs are MAP and SI values.

The lower function determines the deviation in chronotropy from normochronotropy (expressed as % hyper- or hypochronotropy). One scale provides the value for normal, resting, supine adults, the other for the adults in the immediate postoperative period (1-36 hours postoperatively). (The range of normochronotropy is identified).
