The heat transfer coefﬁcient of h c ‹2500 W/m 2 K was chosen to be somewhat lower than the recently determined values [20,23], to reﬂect the fact that the cryogen spray, as used in this study and related experi-ments [17], does not fully develop during a 6 msec spurt [22]. WebIn summary, at the evaluated commonly utilized cryogen pa- rameters, CSC may cause acute erythema and more rarely urtic- aria and transient hyperpigmen- tation. No evidence of cryogen- induced permanent skin dyspig- mentation or scarring was found. CSC offers a safe method of selective epidermal cooling with minimal risk of cryoinjury.
