Effects of arterial blood gas levels on cerebral blood flow and oxygen transport
Near Infra-Red Spectroscopy (NIRS) is a non-invasive technique which can be used to investigate cerebral haemodynamics and oxygenation with high temporal resolution. When combined with measures of Cerebral Blood Flow (CBF), it has the potential to provide information about oxygen delivery, utilization and metabolism. However, the interpretation of experimental results is complex. Measured NIRS ...
متن کاملInterpretation of Arterial Blood Gas
تجزیه و تحلیل گازهای خون اطلاعات مهمی را در مورد اکسیژناسیون شریانی و تعادل اسید - باز در دست ما قرار می دهد. در ک این داده ها بخشی اساسی از مراقبت پرستاری در اکثر بیماران است. هنوز برای بسیاری از پرستاران، تفسیر نتایج گازهای خون شریانی همانند یک جدول پیچیده بوده و در مواقعی که بررسی تمام نتایج در اسرع وقت مورد نیاز باشد، این مشکل بیشتر نمایان می شود.
متن کاملEffects of extra-intracranial arterial bypass on cerebral blood flow and oxygen metabolism in humans.
Twelve patients, eleven with a carotid obstruction and one with an occlusion of the middle cerebral artery, were studied before and after a successful unilateral extra-intracranial arterial by-pass, (EIAB) using PET and the 15-0 steady-state technique to measure regional cerebral blood flow (CBF), oxygen extraction fraction and oxygen metabolic rate (CMRO2). In the whole group of patients, both...
متن کاملCerebral Blood Flow and Oxygen Consumption in
HE BLOOD FLOW AND OXYGEN METABOLISM of the human brain has been studied intensively since Kety developed the inert gas method in 1945. More than 200 clinical studies employing this method have been published so far, and now the former terra incognita is well mapped out. The information gained from all these studies will form the subject of the present review. It will also include, however, the ...
متن کامل[Cerebral blood flow, cerebral blood volume, oxygen utilization and oxygen extraction fraction: the influence of age].
OBJECTIVE To analyze the changes of cerebral blood flow (CBF), cerebral blood volume (CBV), oxygen utilization (CMRO2) and oxygen extraction fraction (OEF) with age. METHODS The PET images of 7 young (21.0-/+1 years old) and 7 aged volunteers (60.9-/+4.7 years old) were analyzed to identify the areas where CBF, CBV, CMRO2, OEF had significant differences with age. The images were anatomically...
