COD N2 acid-base

QuestionAnswer
What does the abbreviation pH stand for Potential Hydrogen
The measurement of the concentration of hydrogen ions in a liquid pH
What makes the acid-base of the body balanced The lungs and kidneys help maintain a normal pH either excreting or retaining acids and bases
What is the relationship between hydrogen ions (H+) and pH The pH reflects the hydrogen ion concentration of the solution: The higher the hydrogen ion concentration, the lower the pH
What are the parameters (ranges) for pH of arterial blood 7.35-7.45
At what point does the pH of arterial become acidic 7.34
At what point does the pH of arterial become alkalotic 7.46
The pressure of the carbon dioxide in the blood-stream PCO2
Interpretation of the patient’s acid-base status involves evaluation of three components of the ABG’s pH, PCO2, & HCO3
Normal values of PO2 (the pressure exerted on the arterial wall by the oxygen gas) 80-100 mm Hg
Normal values of PCO2 (pressure of the carbon dioxide in the blood stream) 35-45 mm Hg
Normal values of HCO3 (bicarbonate) 22-26 mEq/L
Normal values of pH (acid measurement) 7.35-7.45
Normal value O2 Sat (oxygen saturation) 97-100%
Who draws ABG's Respiratory, RN's (depending on Hospital policy)
What three control systems regulate acid-base balance Buffers, Kidneys (Renal),Respiration (Lungs)
What is a buffer system prevent excessive changes in the pH by removing or releasing hydrogen ions
