How do you deal with a category 4 pressure ulcer on the heels?

To offload the heels, you could use specialised boots or a wedge in the bed or if you have the OSKA Series2 mattress you can use this to offload the heels by using the Heel Offloader feature.  This allows you fold under the top layer of foam to create a wedge at the foot end that then helps to offload the heels.  The Series2 mattress can be used for high-risk prevention of up to Cat 2 treatment and management. If you have PUs to the heels you can use the Heel Offloader for up to Cat 4 on the heels only as this acts to offload the heel.
