I think it was at least 7 days or possibly ended on the 8th day. I'll have to check, but I know that when I counted the days by each day, rather than from date to date, I came up with more days than what they reported.
But then again, I don't know my left from right hand.
Her tube was removed on a Wed. afternoon and replaced the following Tues. evening. For me that makes 6 and 1/2 days.
