Applanation tonometry for assessing augmentation index and pulse wave velocity requires prospective validation before it can be reliably used as a clinical or research tool.
Applanation tonometry shows promise for pulse wave analysis and velocity assessment but requires further prospective validation before reliable clinical application.
The study of the pulse using the technique of applanation tonometry is undergoing a resurgence with the development of new computerized equipment. We aim here to present a critical review of the uses, potential uses, strengths and weaknesses of the technique of applanation tonometry for the assessment of augmentation index and pulse wave velocity. We will review the technique of applanation tonometry, the physiological factors affecting pulse wave velocity and pulse wave analysis, the changes in pulse wave velocity and pulse wave analysis with pharmacological interventions, and the use of the technique of applanation tonometry as a prognostic tool. We conclude that, although the technique of applanation tonometry initially seems promising, several pertinent issues need to be addressed before it can be used reliably as a clinical or research tool. Importantly, use of the technique of applanation tonometry to derive the central waveform from non-invasively acquired peripheral data needs to be validated prospectively.
Davies et al. (Sat,) conducted a review in Pulse wave analysis and pulse wave velocity. Applanation tonometry was evaluated. Applanation tonometry for assessing augmentation index and pulse wave velocity requires prospective validation before it can be reliably used as a clinical or research tool.
