NON INVASIVE FINGER BLOOD PRESSURE: PRELIMINARY STUDIES USING A MATHEMATICAL MODEL.
Date of Original Version
The specification of devices using the vascular unloading technique of blood pressure measurement until now has been based primarily on direct in-vivo testing. Here, the entire system is described mathematically as a set of finite-difference equations so that the relationship between the finger and sensor can optimized. The resulting model is a 9th-order set of nonlinear equations. The model has been validated by comparison to in-vivo measurements of intra-arterial pressure and optically measured finger vascular volume in humans. In general the theoretical predictions are in agreement with experimental results, indicating that the model will be useful in further work with such devices.
