Infrared radiation should not be used for pressure sores (pressure damage) once they have formed. Pressure ulcers refer to pressure damage, and for patients with pressure ulcers, localized tissues become hypoxic. The purpose of infrared irradiation is to promote circulation by local heating, and if infrared irradiation is used, the metabolism of the local tissues may be enhanced while the demand for oxygen increases, which in turn leads to the paradoxical condition of local tissue hypoxia. Therefore, pressure ulcers should not be irradiated with infrared rays, which not only has no benefit to the patient’s condition, but also increases the damage of local tissue hypoxia. It is recommended that patients change their position frequently on a daily basis to reduce the pressure on one side of the skin. At the same time, under the guidance of the doctor, using the correct treatment and care measures, in order to help the disease as soon as possible treatment recovery.
