Abstract
A method of using a Doppler-tipped catheter to produce an indication of the blood flow through an artery can be used for determining shunt fractions through the ductus arteriosus of a neonatal patient. Alternately, this information can be used in the optimizing of a ventilation perfusion match for the patient. Also disclosed is a method of producing a continuous real-time display of the blood flow in an artery with the use of a computer program which can continually produce an indication of the blood flow through an artery.
