| DAT v1.0 - allows cardiology researchers, clinicans and others to record and analyze arterial blood pressure waveforms recorded from various arterial sites. Diagnostic applanation tonometry (DAT) is a system consisting of an IBM compatible PC, a Millar Applanation Tonometer, and software. It is a computerized diagnostic tool for the clinical assessment of several pulse indices in real time, eliminating the time consuming manual analysis. The DAT system is based on the acquisition of pulses from a peripheral upper body site, which can be a radial, carotid, brachial, axillary, or subclavian artery by applanation tonometry and synthesis of the corresponding ascending aortic pressure wave. The analysis of pressure waves measured invasively or non-invasively by other methods can also be analysed similarly. Synthesis of the ascending aortic wave is possible on account of constancy of transfer function for pressure wave transmission in the upper limb of humans. After synthesising the ascending aortic pulse, relevant physiological parameters are derived automatically. This information can assist the clinician to evaluate the coupling between the systemic circulation and left ventricle, and can enhance substantially the relatively limited information available from the use of a sphygmomanometer. Other features include: on-line analysis, a database for patient files, and a report function. |
