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.
amount of gases (oxygen and carbon dioxide) that are in your blood. To get an ABG, blood is taken directly out of your artery (usually from the wrist) and can be painful. Oximetry is painless but is not as accurate as an ABG. Also, a pulse oximeter does not measure your carbon dioxide level.he blood oxygen level measured with an oximeter is called your oxygen saturation level (abbreviated O 2 sat or SaO 2). This is a percentage of how much oxygen your blood is carrying compared to the maximum it is capable of carrying. Normally, more than 89% of your red blood should be carrying oxygen.
