Normal PCO2 ✔️35-45 mmHg
Normal PAO2 ✔️80-100
Normal SAO2 ✔️94-100
Normal FiO2 ✔️21%
normal base excess ✔️-2 to +2

How do we eliminate Bicarb ✔️By retaining it or excreting it through our Kidneys
What PH indicates acidosis ✔️<7.35
What PH indicates alkalosis ✔️>7.45
What is the formula for Bicarb ✔️Formula 0.1 x (-BE) x kg = Bicarb needed.
, What are the critical ABG's ✔️PH of 7.2
PcO2 of >55
PaO2 of <60
What are some causes of metabolic alkalosis? ✔️Vomiting, too much suctioning, diuretics, steroids,
antacid poisoning, Diamox.
What are some causes of metabolic acidosis? ✔️*renal failure (decreased production of HCO3 as well
as decreased excretion of H+ ions)
*severe diarrhea (increased loss of HCO3)
*lactic acidosis (increased production of acids)
*asprin toxicity (AKA : ASA Toxicity)
*starvation
*anaerobic metabolism secondary to hypoxia (remember cell injury leads to lactic acid production and
accumulation)
Lab values for respiratory alkalosis ✔️PaCO2 < 35, pH >7.45
Lab values for respiratory acidosis ✔️PaCO2: >45
pH:< 7.35
For every 10 mmHg change in PaCO2, what corresponding change is expected in serum pH? ✔️0.08.
Remember the your Potassium will also be effected
Normal sodium levels Na+ ✔️135-145 mEq/L
normal potassium levels K+ ✔️3.5-5.0 mEq/L
Which is the extracellular ion ✔️Sodium
