# Lab case 444 interpretation

Ph = 7.25, that is moderate acidaemia.

pCO2 = 58 mmHg, so we have respiratory acidosis.

# Lab case 444

18 year-old-girl presented to ED with reduced level of consciousness. She is known to by drugs online.

Her venous blood gases showed the following:

PH = 7.25

# Lab case 443 interpretation

PH = 6.9, that is severe acidaemia/

pCO2 = 72 mmHg. o, we have respiratory acidosis.

# Lab case 443

20 year-year-old man brought to ED after a car accident. His blood pressure was 80/41 and he was unconscious. His blood gases showed the following:

PH = 6.9

# Lab case 442 interpretation

Question 1

PH = 7.236, that is moderate acidaemia

HCO3 = 12.5 mmol/L. So we have metabolic acidosis.

Next we need to calculate the compensation and the the anion gap.

# Lab case 442

44 year old man presented to ED with fatigue and weakness. His blood gases showed the following:

PH = 7.236

PCO2 = 30 mmol/L

# Lab case 441 interpretation

PH = 7.15, that is severe acidaemia

HCO3 = 6.5 mmol/L, so we have metabolic acidosis.

Since we have metabolic acidosis, then we need to calculate compensation and anion gap.

# Lab case 441

An unconscious young girl, was brought to ED by ambulance. Apparently she ingested an unknown substance during a party. Her venous blood gases showed the following:

PH = 7.15

pCO2 = 19 mmHg

# Lab case 440 interpretation

PH = 7.396, that is within normal range, very slightly to the acidaemic side/

pCO2 = 52 mmHg, that is high. It is suggestive of the presence of respiratory acidosis

HCO3 = 31 mmol/L, that is high and suggest the presence of metabolic alkalosis.

# Lab case 440

80-year-old lady presented with confusion. Her Venous blood gases showed the following:

PH = 7.396

pCO2 = 52 mmHg
