Thank you Sybil. It appears he did indeed puncture the lung. They are hoping it will heal itself, so the next few days will tell. We wait for their decision on surgery for the ribs, but I think it is a foregone conclusion that the surgery will happen in the next few days. Poor guy. But his family has rallied around him, so that is good to see too. To some extent they are estranged, but come bad times they are still there.
