Decubitus ulcers, also known as pressure ulcers or bedsores, form when prolonged pressure cuts off blood supply to the skin and underlying tissues. Here’s how they develop:
1. Constant Pressure: When a person remains in one position for too long, the weight of their body presses against the skin, especially over bony areas like the hips, heels, and tailbone.
2. Reduced Blood Flow: This pressure reduces blood flow to the affected area, depriving tissues of oxygen and nutrients.
3. Tissue Damage: Without adequate blood flow, the skin and underlying tissues start to break down, leading to cell death.
4. Ulcer Formation: Over time, this can result in an open wound or ulcer.
Early stages may present as red, discolored skin that doesn’t blanch (turn white) when pressed. If untreated, the ulcer can deepen, affecting deeper layers of tissue and potentially leading to serious infections.
