Acid Base Balance is characterized by - Hydrogen atoms too many means more acidic
too little means less acidic
pH is - how hydrogen concentration is
... [Show More] measured lower pH means higher acidity, higher
pH means lower acidity
What are the main 3 ways the body controls pH? - -Hydrogen atoms ("buffy
buffer"/chemical buffer/metabolic buffer)
-Respiratory system (carbonic acid)
-Renal system (bicarbonate)
Gastric Juice pH - 1.0 - 3.0
Urine pH - 5.0-6.0
Arterial blood pH - 7.35-7.45
Venous blood pH - 7.31-4.41
CSF pH - 7.32
Pancreatic fluid pH - 7.8-8.0
When acid base is balanced it is characterized by? - fluid containing equal number of
positive charges, ions with negative charges
Changes in acid base balance can affect - -shape of hormones and enzymes
-distribution of other electrolytes
-excitable membranes
-effectiveness of hormones and drugs
ABG (Arterial Blood Gas) measures - the acidity (pH) and the levels of oxygen and
carbon dioxide in the blood from an artery
what are 3 parts to an ABG - -pH 7.35-7.45
-Co2 35-45 (this is an acid) (higher the number more acidic)
-Hco3 22-26 (bicarb)
Respiratory issue= - renal system compensates
Metabolic issue= - lungs compensate
if pH and Co2 same side= - respiratory issueif pH and HCo3 same side= - metabolic issue
Compensated means - the pH is normal
pH#low H#high = - acidic
pH#high H#low= - alkalotic
If you kick up the pH what goes down - the acidosis
too much Co2 retained= - respiratory acidosis
too much Co2 excreted= - respiratory alkalosis
too much acid= - Metabolic acidosis
too much base= - alkalosis
Acids: - release hydrogen ions when dissolved in water
Bases: - bind with hydrogen ions in solutions
buffers: - critical in maintaining normal body fluid pH
body fluid chemistry: - -bicarbonate ions (HCO3)
-Relationship between CO2 and hydrogen ions
-Calculation of free hydrogen ion level
Acids cause: - -incomplete breakdown of glucose
-breakdown of protein and fats
-destruction of cells [Show Less]
