Anion gap is

Answer 8

An increased anion gap indicates an increase
in the concentration of anions other than
chloride or bicarbonate

sat Base	excess +/-2	mEq/L if	base	excess	low	i.e.	minus	3	or	below	-> metabolic	acidosis
7.35	- 7.45 4.5	– 6.0	kPa 10	– 13	KPa
96	– 100	%

Question 17

When looking at ABG what do we look at in which order

Answer 17

First PH
PaCO2 (Respiratory component)
HCO3 (metabolic component)
