What are Pressure Ulcer/Bed Sores?
Even though it is the largest organ of the human body, the skin does not receive as much attention as the other organs. This “negligence” can have severe impact on a critically ill patients admitted to the ICU. Patients bedridden for a long time face the risk of developing pressure ulcers on their skin.
- When skin is in direct contact with the mattress for longer periods of time pressure ulcers occur due to tissue ischemia (reduced blood flow) in the skin.
- It usually occurs on bony prominences due to the pressure of the bone against the hard surface.
- Blood vessels get compressed and prevents oxygen and other nutrients from reaching the skin cells.
- This leads to skin breakdown which further leads to ulcer formation.
