92 y.o. bed and chair-bound male who wears diapers for incont. how 2 minimize sores on buttocks due 2 sitting all day? very limited mobility. thank u!

Rotation: Must change point of maximum wt on skin by changing patients position every 2-4 hours, easier said than done in this case however, he is lucky you care.

Stasis ulcers: Mobile people shift their weight an move constantly which changes the pinching effect weight has on the point of contact with chairs/beds/etc. Bones over this impact point press down due to weight and that pinching effect reduces blood flow through the area.That reduced blood flow eventually causes the sore. The more often you can shift his position, the less likely he is to get stasis ulcers.
