Acid/Base Flashcards
The relationship/chemical ties btw Co2 and bicarb
H2O + Co2 H2Co3 H+ + HCO3-
Our version of HH equation to know
pH = 6.1 + log (HCO3/(pCO x .03))
Decreased pH + Increased CO2 indicates…
Respiratory Acidosis
Decreased pH + Decreased CO2 indicates…
Metabolic Acidosis
Increased pH + Increased CO2 indicates…
Metabolic Alkalosis
Increased pH + Decreased CO2 indicates…
Respiratory Alkalosis
Anion Gap Equation
Na-(HCO3-Cl)
Normal Anion Gap is…
Under 17 mmol/L
K response to pH changes
Increased in acidosis
Decreased in alkalosis
Normal levels of Co2 and HCO3
CO2 - 40
HCO3 25
Two ways kidneys can deal with acidosis
Increased HCO3 retention
Increased H+ secretion
Most common causes of acute respiratory acidosis
Oversedation, anesthetics, Head Trauma
Most common causes of chronic respiratory acidosis
Obstructive Lung disease, Extreme obesity (Pickwickian Syndrome)
Why you need to worry about treating resp. acidosis in COPD patients
Chronically elevated CO2 make O2 take over as the controller of ventillation. Too much O2 therapy may repress drive to breathe
Normal anion gap matabolic acidosis is probably caused by…
Loss of HCO3 from GI or kidney
