Abstract
Non-invasive measurements of blood oxygen desaturation in electrically paced sheep latissimus dorsi muscle (LDM) were made using near infrared spectroscopy (NIRS). The theory of NIRS measurements of blood oxygen desaturation and blood volume is well established (Jobsis, 1977; Elwell et al., 1994, Chance et al., 1988). Our aim was to monitor changes in muscle vascular desaturation during electrical stimulation of the muscle using burst pacing. Establishing the properties of skeletal muscle during burst pacing is important because burst pacing is used to stimulate skeletal muscle, in particular the LDM, during cardiac assist.KeywordsNear Infrared SpectroscopyContracting MuscleBlood Flow RestrictionLatissimus Dorsi MuscleBlood Oxygen SaturationThese keywords were added by machine and not by the authors.
