What to expect?

Hi— sitting in the hospital as my husband woke up having trouble breathing. He’s been diagnosed with PE but that was at 10a. He’s had a cat scan, they have him on heparin and they’re scheduling an ultrasound.

He seems really crappy, his body is cold, he has a massive headache and he’s very weak. But they’ve already said he’ll be here a couple of days so it doesn’t seem like the symptoms are dire.

What can I expect for the next couple of days in the hospital? Anything I should look out for? What about after?
