What is the normal NIR?

Normal values for NIRS values are between 60–75\% but physiological values of 55–60\% have been reported in some cardiac patients [7]. Therefore, trends in values are considered more important in clinical practice than the absolute values [8].

What is an NIR test?

What is a prothrombin time test with an INR (PT/INR)? A prothrombin time (PT) test measures how long it takes for a clot to form in a blood sample. An INR (international normalized ratio) is a type of calculation based on PT test results. Prothrombin is a protein made by the liver.

What do NIR mean?

NIR stands for Near Infrared Reflectance. NIR spectroscopy is the study of the interaction between a sample (e.g. cereals, seeds, oils, finished products) and infrared light that has been dispersed into individual wavelengths, usually by a prism.

How is NIR calculated?

The natural increase is calculated by subtracting the death rate from the birth rate. For example, if the birth rate is 14 per 1,000 population, and the death rate is 8 per 1000 population, then the natural increase = 14 – 8 = 6.

What is a NIRS monitor?

Near-infrared spectroscopy (NIRS) is a noninvasive technology that continuously monitors regional tissue oxygenation. Originally used for assessment of oxygen saturation of the brain, its use has now been expanded to evaluation of oxygenation of tissues other than the brain.

What is a high natural increase rate?

Meanwhile the rates of natural increase in industrialized countries are very low: the highest is approximately 1 percent, most are in the neighbourhood of several tenths of 1 percent, and some are slightly negative (that is, their populations are slowly decreasing).
