Fractional flow reserve is defined as the pressure after (distal to) a stenosis relative to the pressure before the stenosis. [2] The result is an absolute number; an FFR of 0.80 means that a given stenosis causes a 20% drop in blood pressure. In other words, FFR expresses the maximal flow down a vessel in the presence of a stenosis compared to ...
IAS 16 permits two accounting models for measurement of the asset in periods subsequent to its recognition, namely the cost model and the revaluation model. [ 7 ] Under the cost model , the carrying amount of the asset is measured at cost less accumulated depreciation and eventual impairment (similar to the inventory's Lower of cost or market ...
A unit of account [1] is a standard numerical monetary unit of measurement of the market value of goods, services, and other transactions. Also known as a "measure" or "standard" of relative worth and deferred payment, a unit of account is a necessary prerequisite for the formulation of commercial agreements that involve debt.
Coronary flow reserve is used in diagnostics and treatment of patients with conditions such as coronary artery disease and syndrome X. [7] In the treatment of these conditions, vasodilators are used to allow sufficient blood to flow past a stenosis, for example, and the measurement of CFR enables the efficacy of such interventions to be measured.
The instantaneous wave-free ratio (iFR, sometimes referred to as the instant wave-free ratio or instant flow reserve) is a diagnostic tool used to assess whether a stenosis is causing a limitation of blood flow in coronary arteries with subsequent ischemia. iFR is performed during cardiac catheterisation (angiography) using invasive coronary pressure wires which are placed in the coronary ...
A full reserve system is the most obvious alternative to a fractional reserve banking system. This is where banks keep 100% of deposits in reserve, meaning that all deposits are precisely where ...
