Correct electrode and instrument drift
2
Q
Which of the following will shift the O2 dissociation curve to the left?
A
Alkalosis
3
Q
Which electrode on an ABG instrument measures the amount of flow between an anode and cathode?
A
pO2 electrode
4
Q
How many Ion Selective Electrodes does an ABG instrument have? Which electrode(s) is/are the ISE?
A
Two: pH electrode and pCO2 electrode
5
Q
Which of the following causes a shift to the left in an oxygen dissociation curve?
A
Hyperventilation
6
Q
A difference between the voltage of the measuring and the reference electrode is set up across a selective membrane on the measuring electrode. This describes the principle of:
