MSFinals-5091

A 75-year-old man presents with seizures. He has a past medical history of dementia and severe COPD for which he uses salbutamol, ipratropium and oral theophylline. His son reports seeing his father taking a lot of pills this morning.

Given his history of COPD and possible substance toxicity, an arterial blood gas (ABG) was performed.

pH 7.21 (7.35-7.45)
pCO2 3.3kPa (4.5-6.0)
pO2 7.8 kPa (10.0 – 14.0)
HCO3- 18 mmol/L (22-26)

What is the definitive management to treat the possible toxicity?
