A 55 year old smoker with known COPD presents with a 1 day history of dyspnoea, cough and wheeze.
An arterial blood gas is performed on room air.
Review the blood gas and document your interpretation below.

| PaCO2 | 7.9 kPa | 4.7 - 6.0 kPa (35.2 - 45 mmHg) |
| HCO3- | 32 mEq/L | 22 - 26 mEq/L |
| BE | +5.5 | -2 to +2 |
| Na+ | 137 mmol/L | 135 - 146 mmol/L |
| K+ | 4.6 mmol/L | 3.5 - 5.3 mmol/L |
| Cl- | 104 mmol/L | 98 - 106 mmol/L |
