Abstract :
The purpose of this study has been to clarify an effect of ischemia on the causal mechanism in the initial phase of decubitus ulcer formation in rabbit ears. The experiment consisted of blood flow measurement during compression and during remission from compression. The compression protocol compares the single compression and repeated compression. The results showed that the blood flow rate changed in the peripheral zone of the compressed area on repeated compression. The investigations have yielded evidence to suggest the decubitus ulcers are due to the following causal factors: (1) localized ischemia in the compressed area; (2) skin surface blood flow from the rim of the compressed area to the surrounding zone
