The Non Invasive Pulse Tonometer is designed to integrate with a data acquisition system for non-invasive assessment of the cardiovascular system by high-fidelity recording pulse pressure wave contours. It is a stainless steel hand-held wand probe that uses Millar Mikro-Tip technology to ensure accurate reproduction of the pulsatile waveforms even at higher frequencies. The 6 inches (152.4 mm) long and 1/4 inch (6.35 mm) outer diameter wand is connected to a 59 inches (1500 mm) long cable.
It has a Viking connector and therefore requires an appropriate Viking type interface cable:
Once connected, the device can immediately output non-invasive blood pressure waveforms from the carotid, femoral and radial arteries. Used in parallel, the signals from two separate tonometers can be used to derive pulse wave velocity as a measure of arterial stiffness to evaluate a specific patient group or cardiovascular event. The tonometer has been cited in numerous publications evaluating hypertension, arterial stiffness, the augmentation index, heart failure and the response of the central blood pressure system to various cardiovascular compounds.
