The specimen spa
a measurement of the partial pressure of O2, CO2, pH, and HCO3 in arterial blood
What is an ABG?
It is characterized by an abundance of H+ ions in the arterial blood, with a pH of less than 7.35.
What is acidosis?
It is characterized by a decrease of H+ ions in the arterial blood, with a pH of more than 7.45.
What is alkalosis?
This condition causes excessive loss of acids through the GI tract.
What is vomiting?
Typically caused by poor alveolar ventilation, can occur due to an acute or chronic disorder
What is respiratory acidosis?
pH 7.30 on ABG
What is acidosis?
Metabolic process of excessive production or diminished removal of lactic acid as a by product of metabolization of glucose.
What is lactic acidosis?
HCO3 (bicarbonate)
What is a base?
The body blowing off excessive amounts of CO2 through rapid breathing causing respiratory alkalosis.
What is hyperventilation?
The process of which the body uses fatty acids from adipose cells when carbohydrates are unavailable leading to acidosis.
What is ketoacidosis?
pH 7.51 on ABG
What is alkalosis?
Some exit via the lungs; others are buffered and excreted via kidneys.
How are acids excreted from the body?
Supplementation with excessive amounts of these can lead to a metabolic alkalosis
What are antacids?
What is aspirin poisoning?
pH 7.32
CO2 50
HCO3 24
What is respiratory acidosis, uncompensated?
pH 7.5
CO2 50
HCO3 28
What is metabolic alkalosis, partially compensated?
pH 7.25
PAO2 40
HCO3 19
What is uncompensated metabolic acidosis?
pH 7.52
CO2 50
HCO3 17
What is partially compensated metabolic alkalosis?
This diabetic drug can produce life-threatening lactic acidosis by inhibiting functions in the liver
What is metformin?
When excessive O2 is given to a COPD patient causing suppressed stimulus for respiration.
What is reduced respiratory drive?
Patient in the hospital with kidney infection.
pH 7.36, CO2 32, HCO3 20
What is a fully compensated metabolic ABG? Note metabolic due to infection was likely causing acidosis.
pH 7.30, CO2 31, HCO3 19
What is metabolic acidosis, partially compensated?
pH 7.49, CO2 31, HCO3 20
What is partially compensated respiratory alkalosis?
The term for rapid deep respirations in diabetic ketoacidosis
What is Kussmaul Breathing?
Patient vomiting x 3 days.
pH 7.48, PCO2 35, HCO3 28
What is uncompensated metabolic alkalosis?
