Thank you Eric and Christine.
No he is not on fentanly patch any more. He is only taking Hydromorphone. Eric how many seconds should the colour return on finger test. Please advice.

I am surprised from past 3 months he was on fentanly patch and hydromorphone but his blood pressure was okay. Only this month it has been low.
Christine his blood pressure is around 88/ 48 . No he is not eating enough solids. He is more on 4-5 glasses of soup, water, juice plus 4 cans of Nutren 1.5.
He gets nauseated after 4 cans. Although he is also taking anti nausea pill.

Do people get low blood pressure generally during recovery ?

Thanks to both of you for your replies
