• Metabolic Acidosis

  low pH and HCO3-

  HCO3- <22 mEq/L

  pH < 7.35
• Respiratory Alkalosis 


  CO2 is being lost at a rapid rate

  pH goes up
• Respiratory Acidosis


  CO2 is entering the system too fast

  so pH goes down
• when we lose H+ pH goes up
• When we have too much H+ pH goes down
• Too much HCO3 is

  metabolic alkalosis
• too little HCO3

  metabolic acidosis
• Too much CO2 is

  respiratory acidosis
• too little CO2 is

  respiratory alkalosis
• respiratory alkalosis equals

  hyperventilation
• K+ ECF levels drop while rises H+ during...

  acidosis
• K+ ECF levels rise while H+ drops during

  alkalosis
• Cl- follows Na everywhere
• H+ is liberated when Co2 is converted to 


  HCO3
• CO2 is a acid
