They said to bring O in if he started wheezing. He's had a nasty cough for a couple of days, though his other symptons describe the virus the nurse said was going around right down to the change in type of cough. I can hear him breathing now but I'm not sure if it's just b/c his nose has been runny, lots of sneezing and congestion...
Re: what does wheezing sound like?

ETA: This is an audio of wheezing. You can hear the high pitch in the breathing.
Also look at his chest, if its retracting as he takes a breath then he's working extra hard and it can be a sign of wheezing if you can't hear it. Its the first thing I look at when I'm worried about Luc's breathing.
ETA: when Luc wheezes, its not nearly as bad as the audio mrsterry posted, but thats a great example. Its the high pitch sound you hear, though luc's is a little fainter.
