ABGs Flashcards
What is the missing range?
pH = 7.35 to 7.45
PaCO2 = 4.7-6 kPA
HCO3 = 22 to 30 mmol/l
BE = -2 to +2 mmol/L
PaO2 = 10.5 to 14 kPa
What is your interpretation and likely diagnosis?
Compensated metabolic alkalosis – due to antacid abuse
What is the anion gap calculation?
What is the missing range?
pH = 7.35 to 7.45
PaO2 = 10.5 to 14 kPa
HCO3 = 22 to 30 mmol/l
BE = -2 to +2 mmol/L
PaCO2 = 4.7-6 kPA
What is your interpretation and likely diagnosis?
A partially compensated metabolic acidosis due to DKA
What is your interpretation and likely diagnosis?
Uncompensated respiratory acidosis due to a panic attack (CO2 blown off)
What is your interpretation and likely diagnosis?
Uncompensated Metabolic Acidosis though bicarb loss in the bowel
What is your interpretation and likely diagnosis?
Partially compensated Metabolic acidosis due to sepsis (Lactic acid)
What is the missing range?
PaO2 = 10.5 to 14 kPa
PaCO2 = 4.7 to 6 kPa
HCO3 = 22 to 30 mmol/l
BE = -2 to +2 mmol/L
pH = 7.35-7.45
What is your interpretation and likely diagnosis?
Uncompensated Resp acidosis due to Guillian Barre and muscle paresis of chest wall
What can cause a Metabolic acidosis with normal anion gap?
Bicarb Loss (Diarrhoea) & decreased acid excretion (renal disease)
What is the missing range?
pH = 7.35 to 7.45
PaO2 = 11 to 13 kPa
PaCO2 = 4.7 to 6 kPa
BE = -2 to +2 mmol/L
HCO3 = 22-30 mmol/l
What is your interpretation and likely diagnosis?
Respiratory acidosis with partial compensation representing an acute worsening upon chronic acidosis
Name 3 causes of Metabolic Acidosis
What is your interpretation and likely diagnosis?
Normal ABG but in context of hyperventilating asthma patient on 15/L indicates a tiring patient. VERY Dangerous sign
What is your interpretation and likely diagnosis?
Uncompensated Metabolic acidosis due to muscle breakdown releasing lactic acid and potassium
What is the missing range?
pH = 7.35 to 7.45
PaO2 = 10.5 to 14 kPa
PaCO2 = 4.7 to 6 kPa
HCO3 = 22 to 30 mmol/l
BE = -2 to +2
What is the cause of a Metabolic acidosis with raised anion gap?
Raised indicates increased acid production e.g lactic acid, DKA etc.
Name a cause of Respiratory Alkalosis
What is your interpretation and likely diagnosis?
Loss of potassium leading to shift of hydrogen ions into cells. Uncompensated Metabolic alkalosis.
