Question 11

You started Sarah, a 67 year old lady, on supplemental oxygen through a Venturi mask at 24% with 2L/min and have just now received her blood gas results.

Which of these blood gas results would warrant calling your senior to review Sarah as soon as possible?

pH 7.40 and PCO2 6.9 kPa    
pH 7.28 and PCO2 7.1 kPa     green tick
pH 7.38 and PCO2 5.7 kPa    

Well done, correct.
