Intravenous dexamethasone

You decide to give Jack intravenous dexamethasone for his breathing problems. A line is sited with some difficulty and the medication given.

You reassess him:

HR 125/min, RR 35/min, T 37.5 C, SaO₂ 91% in Oxygen.

His chest findings are unchanged – mild recession and reduced air entry on the right side.

You decide to observe him for a few hours while the steroids work. Meanwhile you arrange for a chest radiograph.

What is your next decision?
