Calculating Functional Obsolescence in Cost Approach Regarding a functional obsolescence deficiency that lacks something, the calculation is the difference between the reproduction cost with the curable item and without it, as of the date of appraisal.Note that this is reproduction cost and not replacement cost.Functional obsolescence is the excess cost of adding the item in question, such as an additional bathroom or the new kitchen, to the existing house compared to what it would have cost at the time of construction.Since it is an added item, only the cost new is utilized.unctional obsolescence is the excess cost of adding the item in question, such as an additional bathroom or the new kitchen, to the existing house compared to what it would have cost at the time of construction.

A: Blood oxygen level is measured using pulse oximetry, a noninvasive procedure designed to monitor the delivery of oxygen to peripheral tissue, says Johns Hopkins Medicine. Pulse oximetry uses hemoglobin coloration and blood flow pulsation to measure the blood oxygen level.
Oxygenated blood is blood in which oxygen is attached to the haemoglobin molecules in the red blood cells. It is bright red because the attached oxygen makes the normally blue haemoglobin molecules turn red.When blood has delivered oxygen to the cells, it is described as deoxygenated.It now looks a very dark red because so many of the haemoglobin molecules have turned blue again. The mixture of blue and red molecules looks dark red to our eyes.lood in the arteries is oxygenated. Blood in the veins is de-oxygenated. With the exception of the pulmonary arteries which carry de-oxygenated blood, and the pulmonary veins â¦ that carry oxygenated blood.
