Match the components of an ABG to the correct ranges (these are approximate ranges)
What does the acronym ROME stand for when interpreting ABGs?
HCO₃ over 22 mEq/L indicates metabolic acidosis, which can be caused by DKA, kidney failure, or diarrhea, OR compensation for respiratory alkalosis.
PaCO₂ __________ 35 mmHg indicates the presence of respiratory alkalosis due to hyperventilation OR the respiratory system is compensating for metabolic acidosis.
pH=7.31
PaCO2=15
HCO3=7
HCO₃ greater than 26 mEq/L indicates metabolic alkalosis, which can be caused by excess antacids, vomiting, nasogastric suctioning, OR compensation for respiratory acidosis.
pH on an ABG is a measure of how acidic or basic the blood is, which indicates whether acidosis or alkalosis is present. pH measures ___________________ concentration in the blood
On an ABG, the normal range is between 7.35 and 7.45.
pH values under 7.35 indicate _______________, while pH values over 7.45 indicate _______________ .
Separate your answers with a comma (example: one, two)
pH=7.47
PaCO2=18
HCO3=13
HCO₃ is an important buffer in the blood, regulated by the ______________.
PaCO₂ _________ 45 mmHg indicates the presence of respiratory acidosis due to hypoventilation, OR the respiratory system is compensating for metabolic alkalosis.
