Overview

Experimental study reveals irreversible microvascular collapse from repeated compression compared to single prolonged pressure in mice, highlighting ischemia-reperfusion injury.

Key Points

To evaluate microvascular dynamics and tissue recoverability in murine pressure ulcer models subjected to single versus repeated mechanical compression using an integrated optical imaging system.
Integrated laser speckle contrast imaging (LSCI) and intrinsic optical signal imaging (IOSI) into a multimodal platform within a unified field of view.
Compared a single prolonged compression (6 hours) against repeated compressions (1.5 hours daily for 7 days) in mice using spatiotemporal gradient processing of perfusion data.
Repeated compression led to a progressive microvascular perfusion decline by Day 4 and near-complete flow loss by Day 7, alongside severe hypoxia indicating sustained microvascular collapse.
Single prolonged compression produced transient microvascular disruption followed by steady recovery, with tissue perfusion returning near baseline levels by Day 7.
