  1. Body fluid distribution
    • Extracellular Fluid (ECF)
    • Intracellular Fluid (ICF)
  2. Fluid volume deficits include:
    • Hypovolemia
    • Dehydration
  3. Hypovolemia can lead to:
    Hypovolemic shock
  4. Abnormal Skin Losses include:
    • Diaphoresis
    • (Sweating)
  5. Abnormal Renal losses
    • Diuretic therapy
    • Diabetes Insipidus
    • Renal disease
    • Adrenal insufficiency
    • Osmotic diuresis
  6. GI Losses include:
    • Vomiting
    • Suctioning
    • Diarrhea
  7. Third spacing Losses include:
    • Peritonitis
    • Intestinal obstruction
    • Ascites
    • Burns
  8. Risk factors for Hypovolemia
    • GI - Vomitting
    • Skin - Diaphoresis
    • Renal - Diabtes insipidus
    • Third spacing
    • Hemmorhage
    • NPO
  9. Risk factors for Dehydration
    • Hyperventilation
    • Diabetes Ketoacidosis
    • Enteral feeding w/o sufficient water intake
  10. Expected finding for dehydation
    • Increased hemoconcentration
    • Osmolarity >300 mOsm/L
    • Protein
    • BUN
    • Glucose
    • Urine specific gravity
    • Serum sodium
  11. Expected Clinical findings of dehydration
    • Tachycardia
    • Hypotension
    • Syncope
    • Confusion
    • Weakness
    • Oliuria
  12. Expected finding of hypovolemia
    • Increased:
    • Hemoglobin (Hgb)
    • Hematocrit (Hct)
  13. Hypovolemic shock
    • Organ hypoxia/anoxia
    • Decreased O2 saturation
    • Pulse Pressure
    • Administer Oxygen
    • Fluid replacement (fluid rescusitation):
    • Colloids (plasma, blood, packed RBC)
    • Crystalloids (ringers lactate, NS)
  14. Fluid Volume Excess include:
    • Hypervolemia
    • Overhydration
  15. Causes of overhydration
    Water replacemnt w/o electrolyte replacement
  16. Causes of Hypervolemia
    • Excessive sodium intake
    • Abnormal renal function
  17. Expected finding for overhydration
    • Decreased:
    • Hgb
    • Hct
    • Osmolarity <270 mOsm/L
    • Serum sodium
  18. Expected findings for hypervolemia
    • Increased:
    • BUN
    • Creatinine
    • Electrolytes
  19. Clinical findings for FVE
    • Tachycardia
    • hypertension
    • Tachypnea
    • Confusion
    • Crackles
    • Orthopnea
    • Edema
  20. Tx for Pulmonary edema
    • Give morphine and diuretic
    • Place Pt in high fowler's
    • Prepare for intubation and mechanical ventilation
    • Signs and symptoms is crackles, dyspnea at rest
