Can acute bronchitis/asthma trigger shortness of breathe when lying down? I have attacks after I get up from this. Is it sleep apnea?

Could be bronchitis. It could be the bronchitis or asthma that is triggering shortness of breath when lying down. With either condition you can have excess mucous which can build up when lying down and make breathing difficult. Sleep apnea does not cause shortness of breath usually. See a doctor for treatment to relieve the shortness of breath.
