Overview
Brief Summary
Pressure ulcers are common, distressing and expensive. Currently scoring systems and checks by nursing staff are carried out to assess a patient's risk of developing a pressure ulcer.
The investigators would like to see whether non-invasive measurements can be taken from patients to predict who might be at risk of pressure ulcers to allow us to intervene and reduce the risk of it happening.
Detailed Description
Pressure ulcers are common, distressing and expensive. Currently scoring systems and checks by nursing staff are carried out to assess a patient's risk of developing a pressure ulcer. The aim is to investigate whether non-invasive physiological measurements can be taken from patients to predict who might be at risk of pressure ulcers to allow us to intervene and reduce the risk.
