Abstract
R134a sprays have been widely used as a method to protect the epidermis during laser therapies of hyper-vascular
lesions, such as port wine stains, due to their high heat flux and precise control of cooling duration. Recent studies
have shown that the use of vacuum cups during laser treatment can physically dilate the vasculature of interest and
improve therapeutic outcome. However, the effects of these vacuum pressures, and the corresponding changes in
