Abstract:
A method of monitoring a plurality of physiologic parameters within a living subject, comprising:continuously and tonometrically measuring blood pressure from a blood vessel of said subject without using a cuff, said act of measuring further comprising: (i) measuring a first hemodynamic parameter from a blood vessel of said subject; (ii) compressing said blood vessel; (iii) measuring a second hemodynamic parameter from said blood vessel during at least a portion of said act of compressing; (iv) identifying at least one artifact within said second hemodynamic parameter; and (v) calibrating the first hemodynamic parameter using at least said artifact; measuring a second physiologic parameter from said subject; measuring a third physiologic parameter from said subject; comparing data derived from said acts of measuring to predetermined values of said blood pressure, second, and third parameters, respectively; and identifying when at least a portion of said data bears a predetermined relationship to at least one of said predetermined values.
