Abstract
A method of estimating the reliability of cardiac output (CO) measurements obtained using an arterial waveform analysis (AWA) technique calibrated using thermodilution. During thermodilution calibration: (i) initiating inflation of a cuff that is at a location on the subject, (ii) obtaining a first cuff pressure signal comprising measurements of pressure inside the cuff during inflation, (iii) analyzing the first cuff pressure signal to derive a relationship between oscillations in arterial volume beneath the cuff and pressure in the arteries, and (iv) estimating a first arterial compliance of the arteries for a range of cuff pressures based on the determined relationship, (b) during a second time period that is after the first time period, repeating steps (i)-(iv) to estimate a second arterial compliance of the arteries, and (c) using a result of a comparison of the first arterial compliance and the second arterial compliance to determine a reliability of CO measurements.
