Demonstrates a novel turbine flowmeter for blood flow recording in dogs, highlighting its effective performance.
The flowmeter described is a turbine which can be driven by the bloodstream. In the turbine is a magnet which induces a recordable signal in an adjacent coil. The flowmeter records pulsating flow as well as steady flow; it is insensitive to temperature and wide variations of blood viscosity. The pressure drop is rather high. The baseline and calibration are steady over long periods of time. The flowmeter has been successfully used for continuously recording the systemic output in the dog.
