d
Respiratory acidosis with no metabolic compensation
QuestionChoice
There is raised pH indicating alkalosis. PaCO2 is low which would suggest a respiratory cause of the alkalosis. HCO3- is normal suggesting it is not contributing to or compensating for the alkalosis. This typically occurs in conditions causing hyperventilation, such as during PEs and panic attacks.

a
Respiratory alkalosis with no metabolic compensation
QuestionChoice
There is raised pH indicating alkalosis. PaCO2 is low which would suggest a respiratory cause of the alkalosis. However, HCO3- is normal suggesting it is not contributing to or compensating for the alkalosis. If there was metabolic compensation the HCO3- would be lower than normal (<22).

b
Respiratory alkalosis with metabolic compensation
QuestionChoice
The pH is high rather than low, which is what you would expect in acidosis, making this incorrect. Additionally, if there was metabolic compensation there would be a high HCO3-.

e
Respiratory acidosis with metabolic compensation
QuestionChoice
There is raised pH indicating alkalosis. However, CO2 is low and so this indicates a respiratory cause. Additionally, HCO3- would be high if there was a metabolic cause.

You perform an arterial blood gas on a patient in ED, who presented with shortness of breath. The results are:

|      |    |         |
| -------------- | :-------: | ------------------ |
| pH               |  7.51       | 7.35 - 7.45        |
| PaO₂             | 11 kPa       | 11 - 15          |
| PaCO₂            | 2.8 kPa      | 4.6 - 6.4         |
| Lactate          | 1 mmol/L        | 0.6 - 1.4    |
| Bicarbonate      | 25 mmol/L        | 22 - 30      |

Which of the following best describes the results?
