The problem is that most of the heat transfer in an oven is radiant, so a transparent liquid in a transparent dish is going to get very little heat transfer. Though the air is transparent as well, it need much less heat to get to temperature than water does. One option is to use a non-transparent dish.
The emergency treatment of polycythemia (e.g., in hyperviscosity or thrombosis) is by venesection, the removal of blood from the circulation. Depending on the underlying cause, venesection may also be used on a regular basis to reduce the red blood cell count.
Possible complications of polycythemia vera include: 1  Blood clots. Increased blood thickness and decreased blood flow, as well as abnormalities in your platelets, increase your risk of blood clots. 2  Enlarged spleen (splenomegaly). Your spleen helps your body fight infection and filter unwanted material, such as old or damaged blood cells.
