7 year old poss asthma - practical tips for dust

[Danascully2]

My 7 year old possibly has asthma, is on an inhaler trial, I am attempting to get a doctor's appt for him to review but could be ages before we actually see anyone.
In the meantime I'm trying to reduce dust, especially in his bedroom, but am struggling with how to practically achieve that.
He loves Lego and dismantles it all to build into something else so his floor is permanently covered in a layer of Lego bits. He also loves his teddies and has about a million of them in his bed.
We don't have a room that could be a playroom. I've boxed up some of the Lego but it is still impossible to hoover his room without spending about 2 hours tidying first and I just can't see how I can do that regularly.
Any practical tips for managing dust without banning a 7 year old from playing with teddies and Lego which would be awful?

Yes I will try phoning first thing and see if I can get him on the list for a call back - if not I will try the urgent care centre at the hospital and see if they can do anything useful.

My ongoing tips for asthma/airborne allergies for a home with kids include coverless duvets (bung them in weekly to reduce dust mite build up), robot hoover (if you don't pick it up robot hoover will get it), you can freeze stuffies that you can't hot wash, and air purifiers. I have 1 in the living room and 1 in the room I sleep in - pricey outlay, but worth it. Also doubles up as slight air con for the summer. If it is asthma, the change from inside to outside temperatures this time of year can be brutal. Fans are terrible as they circulate the dust.

An asthma exacerbation, especially for new cases and vulnerable children/elderly, need pretty sharp medical attention. I had one earlier this year and needed a full dose of oral steroids and antibiotics to get it in check, and I already take high dose seretide inhalers. You don't need an asthma nurse for an exacerbation, you need any medical professional to help with the immediate problem before establishing long term patterns/treatments.

My asthma is pretty mild mostly (allergies less so), but I spent a lot of time waiting for ambulances outside as a child when my little brother would stop breathing.
