Hi AWikipedia reference-linkmrina

It must be a very worrying time for you and your friend. A common experience is that when dealing with medical and surgical teams it is very easyto feel not in control - which is exactly right as you have to hand over the control to personnel you hardly know and hope for the best that they will do the best for your friend. These people are usually very busy so it is common for inyeractions to be short and lacking time for them to explain what they are doing and why and in a way that can make you feel you can trust their decision making.

This is over and above if they are really doing the best for your friend or not.

As you are an advocate for your friend i would advise you to engage the Drs in getting them to explain what they are doing qnd why and if you query something just be polite but assertive. It is very important that you can trust the team. If they are inpatient sometimes it helps if you just diclose your concerns and ask them if they could take the time to explain things. If you are not happy with the answer you can ask for a second opinion. Drs generally don't get too defensive about this these days

Any advice we give is necessarily general and you really need specific answers now.

BTW elevation of the limb above the heart line at least for a good period of the day is a good idea.
