LABS:


Albumin: ​3.5-5 g/dL of total protein. → In AKI,​ decreased levels​ could mean severe
burns, severe malnutrition, ​renal disorders.
→ In AKI, ​Increased levels ​could mean dehydration,
severe vomiting, severe diarrhea.

pH: ​7.35 - 7.45 → anything above​ 7.45 ​is a b​ ase,​ which in terms
means alkalotic​ (alkalosis)
→ anything below ​7.35​ is an​ acid,​ which in terms
means acidotic​ (acidosis)

PaCo2:​ ​35 - 45 mmHg → anything ​LESS​ than ​35​ is a ​base, ​which in terms
→ represents respiratory level means alkalotic ​(alkalosis)
→ anything ​ABOVE ​45 is an ​acid,​ which in terms
means acidotic ​(acidosis)
→ < 35 mmHg = ​Hypocapnia
→ ​> 45 mmhG = ​Hypercapnia

HCO3:​ ​24 - 28 mEq/L → anything above ​28 i​ s a​ base,​ which in terms
→ HCO3 represents metabolic means alkalotic​ (alkalosis)
→ anything below ​24​ is an ​acid,​ which in terms
means acidotic ​(acidosis)

PaO2: ​80 - 100 mmHg → < 80 mmHg = ​Hypoxemia
→ pressure of dissolved O2 in blood

SaO2: ​97 - 100% → ​Hemoglobin saturation

Base Excess: ​-3.0 to + 3.0 → indicator of buffering capacity

Blood urea nitrogen (BUN): ​5-25mg → Decreased BUN​: hypervolemia, malnutrition,
liver disease, low-protein diet, & ​dialysis.
→ Increased BUN:​ dehydration, p​ rerenal failure,
or renal failure
