Question about recovery from minimally invasive lung surgery to remove a tumor. [View all]

I had the surgery early Wednesday morning and got home Thursday afternoon. Basically doing well, although my chest feels like Sandy Koufax has been hurling fastballs at it.

One thing: I've got the little plastic incentive spirometer that I'm supposed to be using on a regular basis. Baseline number presurgery was about 2500+. Now it's around half that. Seems like an awful big loss given that a fairly small amount of tissue was taken. The good news is that I'm sleeping OK, bringing up mucus OK, and my SpO2 is around 94%.

Anyone have any experience with this?
