Cardiovascular responses to hypoxic stimulation of the carotid bodies.
• The characteristic cardiovascular responses to systemic hypoxia include tachycardia, hypertension, increased cardiac output, increased total peripheral resistance, venoeonstrictio.ii, and increased ventricular contractility.-'' These responses have been inferentially ascribed to stimulation of the aortic and carotid bodies." However, such a position is not entirely compatible with the observa...
متن کاملPregnancy alters hemodynamic responses to hemorrhage in conscious rabbits.
Pregnant animals are less able to maintain mean arterial pressure (MAP) during hemorrhage compared with nonpregnant animals, but the hemodynamic basis of this difference is unknown. The hypothesis that pregnancy attenuates responses of cardiac output, as well as total peripheral resistance (TPR) and femoral conductance, to hemorrhage was tested in conscious rabbits in both the pregnant and nonp...
متن کاملRole of the carotid bodies in chemosensory ventilatory responses in the anesthetized mouse.
We examined the effects of carotid body denervation on ventilatory responses to normoxia (21% O2 in N2 for 240 s), hypoxic hypoxia (10 and 15% O2 in N2 for 90 and 120 s, respectively), and hyperoxic hypercapnia (5% CO2 in O2 for 240 s) in the spontaneously breathing urethane-anesthetized mouse. Respiratory measurements were made with a whole body, single-chamber plethysmograph before and after ...
متن کاملRole of Chemoreceptor Activation in Hemodynamic Responses to Electrical Stimulation of the Carotid Sinus in Conscious Rats.
Electric carotid baroreflex activation has been used to treat patients with resistant hypertension. It is hypothesized that, in conscious rats, combined activation of carotid baro- and chemoreceptors afferences attenuates the reflex hypotension. Rats were divided into 4 groups: (1) control group, with unilateral denervation of the right carotid chemoreceptors; (2) chemoreceptor denervation grou...
