Question | Answer |
Buffer system | prevents changes in pH of body fluids by removing hydrogen ions |
Extracelluluar buffer system | bicarbonate-carbonic acid - assessed with ABG |
kidneys | regulate the bicarbonate level |
metabolic acidosis | low pH, low bicarbonate |
metabokic alkalosis | high pH, high bicarbonate |
ABG | arterial blood gases-measure acid base balance |
pH | 7.35-7.45 normal range |
PCO2 | 35-45 mmHG normal range |
P02 | > 80 mmHG normal range |
HCO3- (bicarbonate) | 22-26 mEq/L |
Oxygen saturation | > 94% on room air |
metabolic acidosis | can cause headache, confusion, drowsiness, increased repiratory rate depth, nausea and vomiting |
metabolic acidosis | common diagnosis: loss of bicarbonate due to diarrhea, lower abdominal fistula, ureterostomies and use of diuretics |
Treatment includes adminsitering bicarbonate, serum potassium is monitored closely and treat the cause | metabolic acidosis |
metabolic alkalosis | causes are vomiting, gastric suction with loss of hydrogen and chloride ions |
gastic fluid | high acidity when vomiting you loss acid becomes alkaline |
metabolic alkalosis | loss of potassium from diuretic therapy, (Lasix) ,chronic ingestion of milk and calcium carbonate |
metabolic alkalosis | symptoms of decreased calcium tingling of the fingers, dizziness and hypertonic muscles. tachycardia can occur |
Treatment includes restore nomal fluid volume by administering sodium chloride fluids, give potassium, decrease gastric suction, | metabokic alkalosis |
respiratory acidosis | pH is low and the PaCO2 is high |
respiratory acidosis | inadequate excretion of CO2 with inadequate ventilation, increase carbonic acid |
respiratory acidosis | hypercapnea, increase pulse and respiratory rate, increase blood pressure, mental cloudiness or confusion |
COPD | respiratory acidosis |
Treatment bronchial dilators to reduce bronchospasms,antibiotics for infection, hydration, | respiratory acidosis |
respiratory alkalosis | hyperventilating, blowing off of CO2 |
respiratory alkalosis | high pH and low PaCO2 |
anxiety-have thepatient breath more slowly into a paperbag | respiratory alkalosis |
