Just one more thing.
**ADDING THIS:
It is a good idea, to get an air purifier/filter for his room or each room of the house.
My parents got me one, when I was a child.
ALSO, when vacuuming the house... make SURE he is not in the same room. Vacuuming, REALLY kicks up the 'dust' in the room. Wait at least 1 hour, before he goes back into a room, after vacuuming. After vacuuming, the 'air quality' in the home/room, gets really full of dust/kicked up whatever in the air.
ALSO: for me, my case, anything with Sulfa or Sulfites in it, triggers my Asthma. Or alcohol. EVEN Mouth Wash... will make me wheeze....
AND also, cold weather... will make my Asthma/lungs labor.
---------------------------
I have had Asthma since childhood.
It is rare, at least in my living with it.. that I ended up in the hospital.
Once you get a definitive diagnosis, then that will discern things. And his treatment/meds/inhalers/maintenance for it, if he has Asthma.
Asthma is deadly.
Attacks can come on suddenly. Cannot predict it.
Each person being different and when/if an episode is triggered. And what triggers it.
For me, when sick, catching a cold, brings on my Asthma. When I was pregnant with my 2nd child, my Asthma was more prevalent.
When Asthma is in an active state, the oxygen levels do drop, and this is indicated by how much oxygen is in the bloodstream as well. Because a person cannot breathe. Airways are constricted. The lungs cannot expand to breathe. Capacity drops.
Thus the use of Prednisone etc., to reduce inflammation/constriction of the airways, right away. It is very necessary. And use of other inhalers. Of which there are many types. Inhalers are Bronchodilators.
Some work for some, not for others. So, if an inhaler does not improve symptoms/breathing, you must tell the Doc and get a prescription for another type.
As for me, there was only 1 time in my life, where I had to be hospitalized due to my Asthma. But of course, this may not or may be common.
Hard to say.
One thing though: with Asthma, you NEED to take the Meds. Don't think you can just go all natural with it. Because that is a shot in the dark and experimental. Each person is different. Meds are needed, because Asthma is deadly, and if you do not take the meds, you can just put your child in a very bad place, health wise. And Asthma attacks, happen. Acute or not.
Hope your son, recovers well.
All the best....
