pH=7.28
CO2=72
HCO3 =26
What is Respiratory Acidosis?
Metabolic Acidosis
Headache, sluggishness, confusion, hypotension, increased respiratory rate, lethargy, N/V/D, and arrhythmias, hyperkalemia
Respiratory Alkalosis: Tachypnea, anxiety
What is a paper bag and instructing on taking slow deep breaths.
Normal CO2 level

What is Metabolic Alkalosis?
Respiratory Acidosis
Hypoventilation, hypoxia, shallow respirations, headache, confusion, hypotension, weakness, cyanosis, comatose
Respiratory Acidosis
Nursing Care
Reversal of cause, support respiratory status, pulmonary toileting,

What is Metabolic Acidosis?
Respiratory Alkalosis
Tachypnea, anxiety, tachycardia, dizziness, n/v, tingling sensation.
Metabolic Alkalosis
Fix underlying cause, monitor I&Os, replace K, electrolytes
Acid Base Balance Buffering system(s)
What are lungs and kidneys
Ph: 7.55
CO2: 27
HCO3: 25
What is Respiratory Alkalosis?
Respiratory failure, pneumonia, respiratory distress, over sedation
Metabolic acidosis
Reversal of cause, support respiratory status, watch for hypokalemia and hypocalcemia when correcting pH
Bicarb for pH less than 7.1 is indicated.
