Radiator under constant pressure?

Jeff - I would think that if you had air trapped in the cooling system you would experience a problem with overheating, which doesn't seem to be the case. Is this a "new" issue you're experiencing or has this been going on for a while? The reason I ask is because if the cooling system is working properly, there is no reason why the pressure shouldn't remain (it's a sealed system) and usually when the pressure drops it's because of a leak somewhere. The pressure is regulated by the rating on the cap, so anything above that number goes to the overflow tank. If you have a Stant (or similar) radiator tester they have a way to check the cap as well.

Hope the healing process goes quickly.
