Tom is 4 years old and seen with his father at the GP surgery. He has just collected him early from nursery as he had a fever and staff were concerned he was very quiet, drooling and had a muffled voice. There is no history of choking and dad mentioned Tom said his throat was sore this morning.

On examination his temperature is 38.4 °C, respiratory rate 25, pulse rate 140 and oxygen saturations 99% on air. Tom looks grey, is sat leaning forwards and is drooling. He has a history of tonsillitis and frequently requires oral antibiotics.

What is the next most appropriate action?
