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.
(This is the most commonly asked question) Oxygen levels are commonly measured by two techniques. The first is a blood gas in which a blood sample is taken directly from an artery. This is the most accurate assessment of oxygen. The normal oxygen level using this technique is 80-100 (mmHg). The second technique is bloodless and is called pulse oximetry. The result here is not a direct measurement of oxygen but rather represents the percentage of hemoglobin that is saturated with oxygen.
