Bainbridge Reflex – increased intravascular volume in normovolemic pts causes reflex tachycardia independent of increased blood pressure Baricity – density of liquid in relation with CSF Basal Metabolic Rate – minimal metabolic rate, amount of energy liberated per unit time to maintain basal

The Use of Intravenous Atropine After a Saline Infusion in ...

do not develop reflex tachycardia (7). This phenom-enon may result from blockade of cardioaccelerator sympathetic fibers at T1 to T4 and possibly the “reverse” of the Bainbridge reflex. Rapid infusion of blood or saline sometimes produces an increase in heart rate (HR) if the initial HR is slow. This effect was described by Bainbridge in ...

Modelling of Long and Short Term Blood Pressure Control ...

I, Violeta McLoone, declare that the thesis, entitled ‘Modelling of Long and Short Term Blood Pressure Control Systems’, and the work presented in the thesis are both my own, and have been generated by me as the result of my own original research. I con rm that: This work was done wholly or mainly while in candidature for a research degree
