A base deficit indicates an excess of acid. It refers to the amount of base needed to titrate a serum pH back to normal (healthy human-arterial blood pH varies between 7.35 and 7.45) when the contribution of respiratory factors is taken out of the equation. Base deficit is usually reported as a negative base excess.

WebOct 26, 2024 · The SID can be changed by two methods: (1) Concentration change. dehydration: concentrates the alkalinity and increases SID. overhydration: dilutes the alkaline state (dilutional acidosis) and decreases SID.
