Definition of pressor in English:

pressor

adjective ˈprɛsəˈpresər

Physiology

Producing an increase in blood pressure by stimulating constriction of the blood vessels.
〔生理〕（通过刺激血管收缩）加压的，升高血压的

加压反应。
Example sentencesExamples
- The pressor effects of epinephrine may be counteracted by medications such as phentolamine and phenoxybenzamine.
- Of the cardiovascular changes observed during the anaphylaxis in the pithed animals, the initial pressor response was significantly attenuated by the extract.
- Pediatric Advanced Life Support guidelines for VT / VF are consistent with the adult guidelines, except that epinephrine is the only recommended pressor agent.
- With a half-life of 10 to 35 minutes, the pressor effects after a single dose last about 30 to 60 minutes.
- L-NAME at pressor doses tends to decrease urine volume compared with control, whereas L-NAME at a subpressor dose induces diuresis.
- Teramoto et al raise the interesting point that an increase in nitric oxide is responsible for a poor or absent hypoxic pressor response as a cause of hypoxemia.
- Importantly, the doses used for antidiuresis are markedly lower than those needed for pressor support.
- There is usually no need to taper pressor drugs, antibiotics, nutrition, or most other critical care treatments.
- The patient died suddenly in less than 12 hours after presentation, in spite of supportive measures, including ventilation, antibiotic coverage, pressor therapy, and multiple transfusions of blood products.
- High erythropoietin levels can elevate blood pressure either via a polycythemia/hyperviscosity mechanism or by direct pressor effects.
- This finding suggests a direct pressor effect in patients with normal function of the posterior lobe of the pituitary gland.
- Imadojemu and coworkers studied the mechanism of the pressor response in 11 patients with obstructive sleep apnea.
- If a pressor agent must be used, a direct-acting alpha-adrenergic agonist such as norepinephrine is preferable because it acts without releasing intracellular amines.
- Later that day, he developed cardiogenic shock, requiring numerous pressor agents and the aortic balloon pump to maintain his cardiac output.
- Almost any infusate can be instilled at a rapid rate through an intraosseous line, including blood and blood products, Plasmanate, glucose, crystalloids, pressor agents including epinephrine, dopamine and dobutamine, and atropine.
- Women destined to develop HIP reportedly lose refractoriness to the pressor effects of infused angiotensin II by wk 18 of pregnancy, whereas calcium supplementation increases refractoriness to angiotensin.
- None required pressor support or steroid treatment for hypotension.
- Vascular pressor responses to hypoxia are increased in patients with obstructive sleep apnea.
- In an animal model of hepatopulmonary syndrome, NO-dependent increases in HO - 1 expression appeared to contribute to the blunted hypoxic pressor response seen in this condition.
- Such protective action on pressor response, if any, may appear as an alleviation of reduced coronary flow in isolated hearts.
