Vasospasm refers to a condition in which an arterial spasm leads to vasoconstriction. This can lead to tissue ischemia (insufficient blood flow) and tissue death ( necrosis ). Along with physical resistance, vasospasm is a main cause of ischemia.
Vasocongestion is essential for sexual procreation in mammals since this is the force that causes the hardening of a penis during an erection.The same force leads to the hardening of the clitoris and vaginal lubrication during sexual arousal. [1]
Alpha 1 blockers inhibit vasoconstriction normally initiated by the baroreceptor reflex upon postural change and the subsequent drop in pressure. [26] Other antihypertensive medications may also cause orthostatic hypotension, in addition to anticholinergics , dopaminergic drugs, opiates and psychoactive medications .
Vasoconstriction is the narrowing of the blood vessels resulting from contraction of the muscular wall of the vessels, in particular the large arteries and small arterioles. The process is the opposite of vasodilation , the widening of blood vessels.
Aortic regurgitation (AR), also known as aortic insufficiency (AI), is the leaking of the aortic valve of the heart that causes blood to flow in the reverse direction during ventricular diastole, from the aorta into the left ventricle.
The ICD-10 Procedure Coding System (ICD-10-PCS) is a US system of medical classification used for procedural coding.The Centers for Medicare and Medicaid Services, the agency responsible for maintaining the inpatient procedure code set in the U.S., contracted with 3M Health Information Systems in 1995 to design and then develop a procedure classification system to replace Volume 3 of ICD-9-CM.
Even when marked, hypocapnia is normally well tolerated. Symptoms include tingling sensation (usually in the limbs), abnormal heartbeat, painful muscle cramps, and seizures. Acute hypocapnia causes hypocapnic alkalosis, which causes cerebral vasoconstriction leading to cerebral hypoxia, and this can cause transient dizziness, fainting, and ...
The signal can be altered also by shock or hypothermia states because of the peripheral vasoconstriction or arterial spasm. Usually, for calculating the stroke volume, the methods based on pulse wave analysis need previous and periodic calibrations that must be done in the same patient, which is a drawback.
