pressor response

pressor response

increase in arterial blood pressure in response to various internal or external conditions or to drugs, e.g. mental stress, sustained handgrip or other isometric exercise. A cold pressor response occurs on immersion of all or part of the body in cold water. See also static exercise.

On the other hand, methylphenidate is an inhibitor of dopamine reuptake with no affinity for TAAR1 (14) or the serotonin transporter,15 and does not induce a pressor response nor increase risk for SS when combined with MAOIs.
3] Another population-based study done on 9864 men and women aged 18-70 years and followed for 18 years also showed that pressor response to cold was higher in menopausal as compared to fertile women.
Neuronal nitric oxide synthase activity in the paraventricular nucleus buffers central endothelin-1- induced pressor response and vasopressin secretion.
Braude et al also have found no significant difference in pressor response between endotracheal intubation and laryngeal mask insertion.
Aerobic exercise continuous and interval: pressor response acute in guy with metabolic syndrome and disease ischemic - Case Study
Vasopressin levels of more than 20-30 pg/ml produce a pressor response with causing organ hypoperfusion.
Greater pressor response in older adults is attributed to age related changes in vessel wall and increased peripheral resistance response in response to exercise.
To ameliorate this pressor response, various drugs have been tried including morphine5, remifentanil6, alfentanil7, sufentanil8, fentan- yl9, tramadol10, dexmedetomedinine11, sufentanil12, nalbuphine13,14, esmolol15, clonidine16 and lignocaine17.
Previous studies have reported that heat stress attenuates the pressor response induced by an exercise (Nybo et al.
This results in (a) increased heart rate and contractility, and (b) the pressor response (increased arterial BP) from peripheral vasoconstriction and increased vascular resistance in the less active muscular and visceral vasculature.
The researchers found that almost eight percent of subjects experienced an increase in systolic blood pressure of 10 mmHg or more in response to drug treatment, (a "pressor response") and that it was possible to identify which patients were most likely to exhibit a pressor response by assessing their blood renin levels.
