Hypothesis-generating for sensorless flow monitoring in centrifugal pumps; human validation required before clinical consideration.
A novel flow estimation method for an implantable centrifugal blood pump was developed and tested in vitro and in vivo, offering a potentially less invasive and non-thrombogenic monitoring approach.
Wakisaka et al. (1997) studied this question. Flow estimation of an implantable centrifugal blood pump vs. Measured flow rate by electromagnetic flowmeter was evaluated on Accuracy and stability of the estimated flow. A flow estimation method for an implantable centrifugal blood pump was evaluated across 79 in vitro operating points and during a 40-day in vivo goat experiment.
