Question 5 of 5
A 5-year-old boy with a history of bronchial asthma was rushed to the emergency department with increasing shortness of breath, pyrexia, and a productive cough. He has difficulty communicating due to an inability to complete a sentence. Examination reveals crackles and wheezes in the lower lobes, tachycardia, and a bounding pulse. Arterial blood gas: pH 7.3, PaCO2 68 mmHg, HCO3 28 mmol/L, PaO2 60mmHg. How would you interpret this?
