The meaning of PERFUSIONIST is a certified medical technician responsible for extracorporeal oxygenation of the blood during open-heart surgery and for the operation and maintenance of equipment (such as a heart-lung machine) controlling it.
Perfusion angiography, where perfusion is defined as the passage of blood through the vasculature and tissue, is a computational tool created to quantify blood flow from angiography images. Perfusion angiography is critical in areas such as stroke diagnosis, where identification of areas with low ...
How is perfusion defined and measured?灌注是如何定义与测量的? Perfusionrefers to the rate of blood flow through the capillary circulation of an organ or tissue. To account for different sized organs, perfusion is commonly normalized as bulk blood flow rate (mL/min) divided by organ mass (per ...
3, up to 70% reduction in vascular resistance of the injured compartment is required for Fshu:Finj ≥ 3 when there is no ventilation-perfusion mismatching in the noninjured-perfused lung. The required amount of vasodilation is reduced as the size of the perfusion defect increases, and ...
Significant improvement in perfusion was defined by a reduction in the volume of hypoperfused brain by 30cc on PWI using time-to-peak (TTP) maps, without enlargement of the infarct. There was a strong, statistically significant association between improved function and improved perfusion: six (75...
Minute ventilation under resting conditions is defined as the amount of air exhaled per minute (). It can be measured readily using a recording spirometer equipped with a carbon dioxide absorber. (The measured expired volume must be corrected for the amount of absorbed carbon dioxide.) Many labor...
(to convert to micromoles per liter, multiply by 17.104) on postoperative day 7; international normalized ratio of 1.6 or higher on postoperative day 7; or graft primary nonfunction within the first 7 days, defined as irreversible graft dysfunction leading to recipient death or emergency re...
Statistical significance was defined as p < 0.05. The entire python software package is published open-source and can be used freely for reproduction studies or other OCTA analysis under https://github.com/clausvdb/OpenOCTAAnalyzer. En face OCT analysis For en face OCT analysis, en face ...
Perfusion and flow extraction product as potential discriminators in untreated follicular and diffuse large B cell lymphomas using volume perfusion CT with... The purpose of this article is to measure perfusion parameters, including transit constant (K(trans)), in untreated follicular and diffuse ...
Circulatory function may be approached by measuring cardiac and respiratory physiology by invasive and noninvasive monitoring and imaging. However, the overall circulation involves tissue perfusion which may be defined as the transport of blood constitue
