Adverse physiologic effects of stored blood is negligible inside the absence of the prior compromise from the Pt's–recipient's position
Existence of electrode poisons inside the measurement medium can corrode the silver/silver-chloride reference electrode and lead to change inside the potential variation. This can be prevented by utilizing a two-chamber electrode and which minimizes the entry from the electrolyte into the reference electrode.
