Construction of thermistor probes suitable for the estimation of cardiac output by the thermodilution method in small animals.

摘要: A method for construction of thermistor probes suitable use in small animals is described, together with some suggestions associated circuitry. The two types probe described are intended cardiac output estimations by the thermodilution method, and although these dimensionally suited to rat, there no reason why they should not be lengthened (or shortened) suit other applications. One used estimating difference between temperature animal cooler, injected indicator passed down right internal jugular vein lie its tip near atrium. recording changes aortic arch produced passage cold through left common carotid artery arch.
