Respiratory Problem

Kidneys
How do the kidneys and lungs collaboratively work together to maintain homeostasis?
By balancing the acids.
What are the acids that the kidneys and lungs collaboratively balance?
pH (Hydrogen), paCO2 (Carbon Dioxide), HCO3 - (Bicarbonate)
ABG results:
Metabolic Acidosis=
Low pH (Under 7.35)
Normal PaCO2 (35-45 mm Hg)
Low HCO3 - (Under 21 mEq/L)
ABG results:
Metabolic Alkalosis =
High pH (Over 7.45)
Normal PaCO2 (35-45 mm Hg)
High HCO3- (Over 28 mEq/L)
ABG results:
Respiratory Acidosis =
Low pH (Under 7.35)
High PaCO2 (Over 45 mm Hg)
Normal HCO3- (21-28 mm Hg)
ABG results:
Respiratory Alkalosis =
High pH (Over 7.45)
Low PaCO2 (Under 35 mm Hg)
Normal HCO3- (21-28 mm Hg)
Step 1 of interpreting ABG’s =
Look at the pH
(Lower than 7.35, the pH is Acidotic)
(Higher than 7.45, the pH is Alkalotic)
Step 2 of interpreting ABG’s =
Look at the PaCO2 to determine the respiratory component.
If less than 35, carbonic acid is being lost, which contributes to alkalosis.
If over 45, carbonic acid is being retained, which contributes to acidosis.
Step 3 of interpreting ABG’s =
Look at the HCO3- to determine the metabolic component.
If less than 21, bicarbonate (A Base) is being lost, contributing to acidosis.
If over 28, bicarbonate (A Base) is being retained, contributing to alkalosis.
