The oxygen level from a pulse oximeter is reasonably accurate. Most oximeters give a reading 2% over or 2% under what your saturation would be if obtained by an arterial blood gas. For example, if your oxygen saturation reads 92% on the pulse oximeter, it may be actually anywhere from 90 to 94%.t also provides a reading of your heart rate (pulse). To make sure the oximeter is giving you a good reading, count your pulse for one minute and compare the number you get to the pulse number on the oximeter. If they are the same, you are getting a good signal.
Agmatine Sulfate is a biogenic amine that is derived from the amino acid L-Arginine. This occurs due to a process called decarboxylation, which is the removal of a carboxylic acid group from the amino acid.
Ammonium sulfate is an ionic compound, composed of two ammonium ions ($\ce{NH_{4}^{+}}$) and one sulfate ion ($\ce{SO_{4}^{2-}}$). As such, you can neglect the sulfate entirely from your consideration of the oxidation state of the nitrogen, as well as treating each ammonium ion as a separate entity.'m trying to find the oxidation number of $ \ce N$ in $ \ce{(NH4)2SO4}$. The answer is supposed to be $-3$ but I can't figure out the logic behind this.
