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.

An improved emergency response system includes a set of databases which relates to volunteer responders and patients, which is controlled by a central system computer. The system interacts with patients and volunteer responders through a wireless network to patient and volunteer communicator devices. The emergency response system calculates and provides a compensation to the volunteer responders based upon their on-duty time, proximity to enrolled patients, and optionally based upon their performance during training and cardiac rescue events.

The invention provides a controller and method for deriving a measure of arterial compliance based on an acquired arterial volume variation signal and an acquired pulse arrival time signal. An oscillometric blood pressure measurement device is used to acquire the arterial volume variation signal. Arterial volume and variation in pulse arrival time are both measured as an applied pressure to an artery are varied by the oscillometric blood pressure measurement device. The arterial volume signal is transformed into a corresponding signal representative of variation in peak-to-peak amplitude of the arterial volume.
