Dr. Spear just visited Greg and told him that his cardiac output is excellent. In fact he claimed it's twice as much as his own. We aren't sure if that's quite true, but in any case it was cheering news.
Since the surgery Greg has had Swan Chest tubes in to drain blood from his upper chest cavity. Fortunately he's not really bleeding, so the tubes are coming out tomorrow.
Also he's been coughing up a lot of mucous and in a good bit of discomfort, but he's on percocet and drifting back to sleep. All in all things are going very well and we hope he'll get restful sleep tonight with his new healthy heart.
