high temp and difficulty breathing

My Grand Daughter is 3 years old, she has a number of incidents where she has a raging temp and difficulty breathing
she also sleeps a lot (more that we see as usual having raised 3 children ourselves) these bouts started around 3 months apart and now more frequent 2 weeks apart
she has been hospitalized for two days, doctors reported that her oxigen levels dropped so low one night that she would have died if she was not in the hospital, doctors THINK it is Asthma and have treated accordingly,
If continues to occur with another attack today

I haven't heard of having a fever with asthma.  has anyone done a lung scan on her? I can't say for sure but my little guy has asthma and when he gets a cold and fever he is qutie bad. when he was younger his o2 sats (oxygen levels) were low and he slept all of hte time reason, cardiac. but he had no feer with this.
Good luck and I hope she will be okay

many thanks, you mention Cardiac. This is exactly what I think the issue relates to
looking at www.wrongdiagonosis.com and searching by symptoms we got Endocarditis and in accute cases High Fever is listed along with her other symptoms

I always say go with your gut instinct. mention it to your doctor. ask them if you can be referred to a cardiologist, what harm can it do. tell them.  if they are hesitant say to satisfy your mind and best case heart little heart is fine.
I hope they can figure it out
good luck
