An arterial tonometer is introduced that can measure arterial volume and pressure. The flexible diaphragm tonometer employs volume feedback control such that the contact surface is apparently rigid. When feedback is disabled, electrical impedance plethysmography of the tonometer compartment allows simultaneous measurement of pressure and volume change in the underlying artery. Applanation pressure is varied as well, to provide volume as function of pressure. It is also shown that a calibrated single artery volume waveform can be obtained for hemodynamic studies.
