Term
Base
Definition
pH > 7
Term
Acid
Definition
pH < 7
Term
Acidosis
Definition
Abnormal condition in which an acid-base imbalance is characterized by a reduction in arterial blood pH
Term
Alkalemia
Definition
A pH imbalance in which the blood levels are slightly to moderately basic
Term
Alkalosis
Definition
an acid-base imbalance characterized by elevatedpH
Term
Buffers
Definition
a substance that can absorb excess acids or bases without causing a significant change in pH
Term
pH
Definition
a measure of the acidity of basicity of a certain fluid
Term
What is the normal pH for blood?
Definition
7.35-7.45
Term
The numerical value of pH is ______ proportional to the number of H ions in the solution
Definition
inversely
Term
What pH is acidosis?
Definition
<7.35
Term
What pH is alkalosis?
Definition
>7.45
Term
What are normal PaCO2 levels?
Definition

35-45 mm Hg

 

<35 alkalosis

 

>45 acidosis

Term
What are normal HCO3 (bicarbonate) levels?
Definition

22-26 mEg/L

 

<22 acidosis

 

>26 alkalosis

Term
What are normal PaO2 (Partial pressure of arterial oxygen) levels?
Definition

80-100 mmHg

 

<80 is considered Hypoxemia

Term
What is the normal SaO2 (oxygen saturation) level? 
Definition

95-100% is normal

 

 

Term
Bicarbonate buffer system
Definition

  • operates in lung and kidney
  • decreases the amount of carbonic acid by blowing off Co2 and leaving water
  • fasting acting

Term
Hemoglobin Pairing
Definition

  • primarily an intracellular buffer system
  • Hemoglobin is bound to Hydrogen and CO2 to form a weak acid

Term
Phosphate Buffering
Definition

occurs in the kidney

 

uses CO2 and H2O to make H2CO3 and secreted from the tubular cell

 

slowest effect, but most effective

 

contributes to alkalinity
