What might be making you a tad apprehensive, but might not, as it's too soon to tell

Mr Limey had a cold all last week, gradually turning into a cough but we decided not to go see the doc on Friday. All weekend the cough and breathlessness kept getting worse and worse so I decided to take him to the ER in our little cottage hospital, and they've decided to keep him for a couple of days .
Obviously there they've got the anti-biotics (giving him them IV), oxygen if required etc., but I wasn't expecting to come home without him. What's making me uneasy is that they called in the radiographer to xray him. Straight away. On a Sunday evening.
