What is an ABG? - ACCURATE ANSWERS✔✔ a measurement of the
partial pressure of O2, CO2, pH, and HCO3 in arterial blood
Who normally draws this bloodwork? Where is it drawn from? -
ACCURATE ANSWERS✔✔ Respiratory therapists draw for this profile
most commonly from the radial, brachial, and femoral arteries.
What is acidosis? - ACCURATE ANSWERS✔✔ It is characterized by
an abundance of H+ ions in the arterial blood, with a pH of less than
7.35.
What are the acids? - ACCURATE ANSWERS✔✔ H+, CO2, and
H2CO3 (carbonic acid)
How are acids produced? - ACCURATE ANSWERS✔✔ They are
produced during metabolic processes.
How are acids excreted from the body? - ACCURATE ANSWERS✔✔
Some exit via the lungs; others are buffered and excreted via kidneys.
What is alkalosis? - ACCURATE ANSWERS✔✔ It is characterized by
a decrease of H+ ions in the arterial blood, with a pH of more than 7.45.
, What are the bases? - ACCURATE ANSWERS✔✔ HCO3 (bicarbonate)
What is a buffer? - ACCURATE ANSWERS✔✔ A chemical substance
that reduces changes in systemic pH by either releasing or binding H+
ions. It is considered to be a moment by moment regulation.
Why is CO2 considered a "potential acid"? - ACCURATE
ANSWERS✔✔ Because it forms carbonic acid when combined with
H2O.
What are compensatory mechanisms? - ACCURATE ANSWERS✔✔
Mechanisms that try to prevent large changes in pH and/or attempt to
correct alterations in acid-base balance; compensatory mechanisms
ALWAYS alter the pH towards a normal level.
Give 2 examples of compensatory mechanisms. - ACCURATE
ANSWERS✔✔ Lungs and Kidneys
What is partial pressure? - ACCURATE ANSWERS✔✔ Pressure
exerted by a single gas.
What is the goal in the regulation of pH? - ACCURATE ANSWERS✔✔
To maintain or restore body pH to a normal level - either through buffers
or compensatory mechanisms.
