Test 3 Study Material Blood Chemistry Testing: PH - measures the blood hydrogen ion concentration PaO2 -is the partial pressure of Ox in blood -measures the ability of lungs to oxygenate blood -higher in arterial blood SaO2 -oxygen saturation level of the blood HCO3- -bicarbonate ion crucial in maintenance of blood PH -regulated by the Kidneys O2CT -actual amount of oxygen in blood Abnormal Values: 1) LOW PaO2 w/ low O2CT w/ low SaO2 & HIGH PaCO2 -indicates not getting enough O2 into the lungs -Causes: muscle weakness, airway obstruction, respiratory center inhibition 2) Normal PaCO2 w/ Decreased PaO2, O2CT, SaO2 - indicates insufficient oxygenation of the blood - Causes: -Pneumothorax -Internal fibrosis -AV shunt -Ductus Arteriosus -Septal Defect 3) Normal PaO2, SaO2, PaCO2 w/ LOW O2CT -indicates severe Anemia (Decreased blood volume, reduced ability of cells to carry O2)

Total Carbon Dioxide - end product of metabolism -venous blood -C02 flowing out of RBC dissolves in plasma as Carbonic Acid -Most of CO2 in plasma is in bicarbonate form Sodium -major extracellular cation -maintains osmotic pressure & acid-base balance -regulates K+ & Cl- levels ***Decrease Na+ levels = more water lost ***Increase Na+ levels = more water absorbed TOO MUCH Na+ = Hypernatremia Causes: -Dehydration -Diabetes Insipidous -Kidney failure -Vomiting or Diarrhea -primary aldosteronism TOO LOW Na+ = Hyponatremia Causes: -inadequate intake -Vomiting or Diarrhea -adrenal insufficiency -chronic kidney disease -burns Potassium -major Intracellular cation Magnesium - enzyme activation to make nucleic acids & proteins -influences PTH levels & Ca+ Phosphates -used to store & utilize energy Calcium -in blood 40% is ionized & 50% is bound

Chloride -works w/ Sodium Anion Gap -tests Na+, Cl-, & bicarbonate -Na+ is 90% cation -Cl- & Phosphate are 85% anions * Normal Gap Acidosis -Happens due to loss of bicarbonate, leads to renal absorption of Na+ & Cl- * High Gap Acidosis -measured by increase in anions, sulfates, phosphates, & lactic acids -results from renal failure Proteins and Metabolites Blood Urea Nitrogen (BUN) -end product of protein metabolism -indirect test for renal function

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
