Low Arterial Pressure
نویسنده
چکیده
Low arterial pressure* (Hypopiesis) is a term applied to low arterial pressure in general, whether physiological or pathological, temporary or permanent, congenital or acquired. Hypopiesia (primary low arterial pressure) is a clinical series of primary congenital, constitutional or familial origin, characterised by persistently lowered arterial pressure occurring as a part of a low vitality state either (a) without apparent physical abnormality, (b) with symptoms of exhaustion, or (c) in association with conditions of suboxidation dependent upon physical abnormalities, such as elongation and narrowing of thorax, aorta and heart.

متن کاملCARDIOVASCULAR RESPONSES TO HYPERCAPNIA AND VARYING LEVELS OF ARTERIAL pH IN THE ANESTHETIZED CAT
Effects of acute hypercapnia on the cardiovascular system (CYS) were studied in the anesthetized cat. After surgery the animal was exposed to a gas mixture of 12% CO2 and 25% O2 in nitrogen, and hypercapnia with low levels of arterial pH (pHa) was produced for 20 minutes. In the second run the same level of hypercapnia was induced by ventilating the same cat from the above gas mixture but ...

Background: Direct monitoring of arterial pressure using a transducer system is not affordable in most operating rooms and ICU wards in Iran. It is, however, possible to use an aneroid manometer instead, but it is not standardized yet, nor studied enough and its measurements may not be interpretable. Methods: To study the correlation of the arterial pressure readings between a manometer and a ...
متن کاملPresentation of a Non-invasive Method of Estimating Arterial Stiffness by Modeling Blood Flow and Arterial Wall Based on the Determination of Elastic Module of Arterial Wall
Introduction: Arterial stiffness is an important predictor of cardiovascular risk. Several indices have been introduced to estimate the arterial stiffness based on the changes in the brachial blood pressure. Since the substitution of the blood pressure changes in the central arteries such as carotid with the blood pressure changes in the brachial results in error in the blood...
متن کاملTHE EFFECT OF ARTERIAL O2 SATURATION AND HE ART RATE ON BLOOD PRESSURE DURING HYPOXIA
A periodic increase in blood pressure (BP) occurs during apneic episodes in patients with obstructive sleep apnea (OSA). Several factors including hypoxemia and an increase in heart rate (HR) were reported to be responsible for this increased BP. To examine the contribution of these two factors in increasing BP, 35 healthy male subjects (mean age±SD= 23.64±3.80) were studied in three experi...
متن کاملPredicting factors of serum lactate in patients under general anesthesia with propofol during spine surgery
Introduction: Increased serum lactate is seen during surgery due to tissue hypoxia. There have been reports of propofol infusion syndrome due to long-term use of this drug, especially in intensive care patients. This study was conducted to evaluate the factors affecting serum lactate levels in patients under general anesthesia with propofol in spine surgery. Methods: In a cross-sectional study...
