P 253 Fluid and electrolyte disorders

Hypovolemic states
It saysecondary to decreased intravascular volume with INCREASED baroreceptor stimulation and increased ADH production.

Shouldn't it be decresed baroreceptor stimulation?

beacuse baroreceptors located at the carotid sinus and arotic arch monitors the strech of the arterial wall as the index of BP, a rise(increase ) in affarent stimulation indicates rise in BP, and loss in Afferent activity signals decrease in BP
Please clarify any one

I think you are right! It is decreased baroreceptor stimulation!
see: Kaplan Step 1 Physiology lecture notes p. 407
Stimuli arising from stretch receptors act to chronically inhibit ADH secretion. So decreased stimulation-decreased inhibition -high ADH.
