Hi, 12/3/2015 I Could Not Breath. My Husband Rushed Me

Hi, 12/3/2015 I could not breath. My husband rushed me to the hospital, and was diagnosed with "Respiratory failure, brought on by a viral Infection". The last couple of weeks, my feet and legs have been swelling, pretty good! I refer to them as "small tree trunks". :) I'm not sure what to do about this. I am on 20mg X's 2 of lasix.
